00:01:04.290 –> 00:01:09.930
Jay Wommack: People are valuable to you. And that’s exactly what we want. That’s what you want. That’s what you people want to hear. So
7
00:01:10.440 –> 00:01:18.510
Jay Wommack: We do have all the answers. We know exactly what we’re doing with web-based training, we’ve doing this for 15 years but I have a special offer day for our prospects that show up.
8
00:01:19.110 –> 00:01:30.990
Jay Wommack: We’d like to offer you a 30-day free trial using our system completely see what it’s all about, see if you like using something like this, you know, remote training is jumped to the forefront.
9
00:01:31.440 –> 00:01:41.970
Jay Wommack: Of the world in the last 90 days, the world has shifted has changed remote training. We’re the experts we know more about remote training them virtually anybody in the entire I guess world, universe.
10
00:01:42.630 –> 00:01:53.880
Jay Wommack: So I want to offer the 30 day free trial, time offers limited. Yeah, we can’t make this go on forever, I wish we could. I’m going to even throw in a CSR Reps. Someone who is a client service rep.
11
00:01:54.390 –> 00:02:00.510
Jay Wommack: That can make this thing hum for you get user activity up on system because that’s the key. Get your people to use the system.
12
00:02:00.900 –> 00:02:08.850
Jay Wommack: I don’t care how many bells and whistles; you’ve got if they’re not going to use it. It’s not going to have an impact on your company. And at the end of the day, that’s what we’re all about.
13
00:02:09.270 –> 00:02:18.930
Jay Wommack: We want to see your top line and bottom line and improve. We want to see your safety record improved. That’s what we do. And we do that better than anybody out there.
14

15
00:02:29.850 –> 00:02:38.700
Mark Rhea: Good morning. Good morning. Good morning. Thank you as always. Jay, for your commitment to our industry and supporting our professional drivers.
16
00:02:39.960 –> 00:02:47.580
Mark Rhea: And its summertime, and we have a great webinar plan today on, Rubber Meets the Road.
17
00:02:48.360 –> 00:02:51.360
Mark Rhea: I’m sure everyone here has seen the remnants of
18
00:02:52.200 –> 00:03:11.280
Mark Rhea: Tire failures on the side of the road. Some of you might have experienced some of those and today I’m very excited to let you know we’ve got some experts, engineers and innovators in the field of tires, tire maintenance, and rapid air loss.
19
00:03:11.910 –> 00:03:14.370
Andrew McCulloch: Events from the Michelin company.
20
00:03:15.060 –> 00:03:29.850
Mark Rhea: So, let’s, let’s get going. My name is Mark Rhea most of y’all know me. I’ve been around the industry for 35 years and it’s a pleasure to represent Vertical Alliance and Infinit-I Workforce Solutions today.
21
00:03:32.400 –> 00:03:42.630
Mark Rhea: Just gives a quick introduction. We’ve got joining us today from the state of California, Mr. Andy McCullouch. Andy is the field operations engineer
22
00:03:43.350 –> 00:03:56.430
Mark Rhea: for Micheline engineering, is a member of Society of Automotive Engineers, and is a certified tire industry instructor originally a Michigander. Andy is a
23
00:03:56.460 –> 00:03:57.120
Andrew McCulloch: Graduate
24
00:03:57.210 –> 00:03:59.040
Andrew McCulloch: Of Michigan State University.
25
00:03:59.790 –> 00:04:17.100
Mark Rhea: Also joining us from the great Bluegrass State of Kentucky, Bryan Dingler. Brian is the services and solutions sales manager for Michelin, North America. And joining us from the Palmetto State of South Carolina. Mr. Charles Whatley.
26
00:04:18.600 –> 00:04:25.920
Mark Rhea: Charles has got a long title there. I’m going to say he’s the innovator for Michelin, North America. He’s got a lot of innovation.
27
00:04:26.580 –> 00:04:28.770
Andrew McCulloch: Technology things working. So, we’ve
28
00:04:28.770 –> 00:04:39.360
Mark Rhea: Got a lot of great guests today. I want to start off with one quick question for the panel. Before we dive into the formal presentation.
29
00:04:41.250 –> 00:04:41.850
Andrew McCulloch: Tires
30
00:04:41.880 –> 00:04:52.890
Mark Rhea: Tires represent a large both direct cost carriers and indirect costs to carriers, the indirect cost carriers of
31
00:04:53.970 –> 00:05:05.730
Mark Rhea: Course, your downtime. But more important in that in our, in our world here is rapid air loss can transfer into rapid vehicle control loss which can
32
00:05:06.450 –> 00:05:17.760
Mark Rhea: Turn into a rollover event or something nasty that we’re trying to prevent so the impacts of a proper tire maintenance what to do in the event.
33
00:05:17.760 –> 00:05:18.840
Andrew McCulloch: That you have
34
00:05:18.900 –> 00:05:26.220
Mark Rhea: A rapid air losses, what we’re going to cover today. So just, just to kind of
35
00:05:27.390 –> 00:05:50.550
Mark Rhea: Prepare you a little bit. We will put on your seat belts; we will be simulating a rapid air last event. And I would also ask you to grab a paper clip. Mr. Andrew McCullough will explain that is part of his presentation. So put on your seat belt. Grab a paper clip and let’s dive into this.
36
00:05:52.320 –> 00:05:53.490
Mark Rhea: Want to go to the next slide.
37
00:05:56.430 –> 00:06:02.460
Mark Rhea: So, before we get there, I was going to ask the panel about those direct costs and those indirect costs.
38
00:06:04.350 –> 00:06:14.820
Mark Rhea: Can awareness training and information exchange impact those direct costs and indirect costs related to tires.
39
00:06:19.110 –> 00:06:21.990
Andrew McCulloch: Thank you, Mark. And welcome, everybody. Thanks for attending.
40
00:06:23.010 –> 00:06:40.320
Andrew McCulloch: The short answer to that question is yes, absolutely. We can. There are certain things we can do several different things that we can do that will help to mitigate both direct and indirect losses and we’ll get into those.
41
00:06:42.240 –> 00:06:54.720
Andrew McCulloch: Let’s first try to understand what type of losses, we’re looking at and what the consequences of those losses are. So why do we care about loss of currencies, what’s important.
42
00:06:55.950 –> 00:06:57.090
Andrew McCulloch: There are multiple different
43
00:06:59.220 –> 00:07:00.090
Andrew McCulloch: Multiple different
44
00:07:00.240 –> 00:07:12.840
Andrew McCulloch: Direct and indirect costs associated with it, for instance, that the average cost of an ERS call is about $700 plus per occurrence and experience has shown us that
45
00:07:13.980 –> 00:07:22.260
Andrew McCulloch: Each vehicle a Fleet will experience an average of about one to one and a half breakdowns per year. Now the anti NHTSA
46
00:07:23.760 –> 00:07:36.360
Andrew McCulloch: Advisors that these types of losses typically result in over 75,000 accidents per year. So, there’s a serious dollar value behind
47
00:07:37.290 –> 00:07:46.560
Andrew McCulloch: You know, these rapid air losses and tire issues and they can have both direct consequences to the fleet in the form of not just
48
00:07:46.950 –> 00:07:58.800
Andrew McCulloch: Tire failures, replacing tires and damaged equipment but indirect consequences as well. Insofar as driver downtime, delays, and shipments and that sort of thing.
49
00:07:59.820 –> 00:08:01.170
Andrew McCulloch: So, we go to our next slide.
50
00:08:06.450 –> 00:08:08.010
Andrew McCulloch: Here losses are actually can be
51
00:08:09.390 –> 00:08:20.580
Andrew McCulloch: classified into two types, they can be a rapid hair loss, or they can be a gradual, but both of them are important. Both are of a concern to us and
52
00:08:21.450 –> 00:08:32.460
Andrew McCulloch: And there is a difference between the two. And if we go to the next slide will show an example here. Here we have two tires that failed for two very different reasons.
53
00:08:33.480 –> 00:08:46.200
Andrew McCulloch: If you look, the tire on the left. That was a rapid hair loss that resulted from an impact with a solid object. Now, this could be a pothole in the road. This could be a curb
54
00:08:46.710 –> 00:08:55.680
Andrew McCulloch: Number of different things. But if you look at the rupture in the side wall that tires. You’ll notice it forms a distinctive T pattern that T shape.
55
00:08:56.280 –> 00:09:08.670
Andrew McCulloch: And that is almost always indicative of an impact failure. So, we had that tire contact a sharp edge or object right at the center T of that rupture.
56
00:09:09.360 –> 00:09:22.170
Andrew McCulloch: And that impact causes the tire to rupture it cause the casing plies to fail and a rapid air loss. Now conversely if you look at the tire on the right-hand side.
57
00:09:23.250 –> 00:09:33.120
Andrew McCulloch: That is what we call a zipper rupture and that does result in a rapid hair loss, but for very different reasons. The cause is from a very different cause
58
00:09:33.600 –> 00:09:53.550
Andrew McCulloch: This is typically caused by a low air pressure scenario. So, we have a situation where a tire for whatever reason is under inflated and maybe from a slow leak. It may be a nail in the tire, the number of different things can cause it. But what happens is that the tire rolls down the road.
59
00:09:54.630 –> 00:10:04.320
Andrew McCulloch: When it comes into contact with the road surface what tends to happen is the tire flexes sidewall flexes, it’s a certain amount of the flexing that occurs
60
00:10:04.680 –> 00:10:18.360
Andrew McCulloch: in that side wall as a contact, the road surface when it leaves the road surface it flexes back to its original position and inside the tire and you can see on that picture, the number of
61
00:10:19.560 –> 00:10:24.990
Andrew McCulloch: Wires or cables, which form what’s called the casing plies. These cables run
62
00:10:25.560 –> 00:10:37.200
Andrew McCulloch: Radially hance the name radial tire from one bead right around the tire radio to the other and they actually flex as they contact the road surface. These are what support the load.
63
00:10:37.860 –> 00:10:46.860
Andrew McCulloch: It’s actually not the rubber that supports the load it’s these cables and now this is where our paperclip comes in, into play.
64
00:10:47.340 –> 00:11:06.780
Andrew McCulloch: These cables are designed to flex a certain amount. And that’s perfectly okay but what happens is when they start when you have a tire that is under inflated or overloaded, or both. The amount of deflection that occurs in those tires in those cables becomes very excessive and
65
00:11:07.980 –> 00:11:09.450
Andrew McCulloch: The tire will flex in its
66
00:11:10.590 –> 00:11:11.340
Andrew McCulloch: sidewall
67
00:11:12.540 –> 00:11:26.100
Andrew McCulloch: beyond what it’s designed to do, and that causes fatigue sidewall fatigue. It causes these cables to sort of the fatigue. So, if we take that paperclip as an analogy to what’s happening in the side of this tire.
68
00:11:26.610 –> 00:11:33.150
Andrew McCulloch: If we take that paperclip and we start bending it back and forth. The same thing happens with a coat hanger or I’m sure everybody’s done this.
69
00:11:33.720 –> 00:11:43.710
Andrew McCulloch: You start bending back and forth and two things start to happen when you feel it starting to heat up and that’s because of the metal crystallization, and the friction caused internally.
70
00:11:44.520 –> 00:11:58.350
Andrew McCulloch: And two, eventually you’ll notice what happens if it breaks and the same thing happens to these cables in the casing ply and it doesn’t matter what type of tired, is whether it’s a Michelin or or whatever brand.
71
00:11:59.220 –> 00:12:05.310
Andrew McCulloch: Any commercial tire that uses this manufacturing technology will experience the same sort of thing.
72
00:12:05.880 –> 00:12:13.710
Andrew McCulloch: So we get what we could sidewall fatigue occurring and these cables start to fatigue, they start to fray and they start to break.
73
00:12:14.340 –> 00:12:27.240
Andrew McCulloch: And over time, this leads to a situation with the condition we call the run flat condition, and it may very well result in a rapid air loss. As you can see this tire.
74
00:12:28.170 –> 00:12:39.720
Andrew McCulloch: Resulted in a rapid air loss. It was, it’s called a zipper rupture. Because what literally happens is each cable breaks and snaps and that puts additional strain and stress on the one
75
00:12:40.110 –> 00:12:54.960
Andrew McCulloch: next to it which breaks again and so on and so on, very much like the zipper unzipping. That’s why we call it a zipper rupture. So, the end, the importance of this is the reason we touch on this is the number one.
76
00:12:56.850 –> 00:13:08.850
Andrew McCulloch: Cause of tire failures tends to be under inflation and or overload and this is why it’s an important concern, it can lead to a gradual air loss.
77
00:13:09.630 –> 00:13:23.700
Andrew McCulloch: Or it can lead to a rapid hair loss. In either case, the net result is you know an air loss, a tire that has failed and results in costs, direct and indirect to the fleet.
78
00:13:24.720 –> 00:13:26.220
Andrew McCulloch: So, let’s go to our next slide please.
79
00:13:28.110 –> 00:13:29.940
Andrew McCulloch: Hopefully, everybody’s following along here.
80
00:13:32.790 –> 00:13:50.670
Andrew McCulloch: So what factors can trigger a sudden air loss what factors come into play and results in the tire failure. And there are several different factors. But the most important ones and the primary ones are under inflation or overloading, as we mentioned,
81
00:13:52.200 –> 00:13:58.890
Andrew McCulloch: And that’s something that we can mitigate. That’s something we can control in our risk management processes to help reduce.
82
00:13:59.880 –> 00:14:05.070
Andrew McCulloch: We also have road hazards and driving practices. Now these are a little bit more difficult.
83
00:14:05.610 –> 00:14:15.390
Andrew McCulloch: You can get objects enhancers in the road, ranging from potholes, to debris, all sorts of things, but we can mitigate those to a certain degree.
84
00:14:16.380 –> 00:14:25.320
Andrew McCulloch: Depending on our driving practices and other external conditions. And of course, we also have heat and tire fatigue and both of these are
85
00:14:26.040 –> 00:14:34.470
Andrew McCulloch: to some degree, are related to our number 1 point are there under inflation or overloading of the truck both Wheel heat and tire fatigue.
86
00:14:34.950 –> 00:14:51.780
Andrew McCulloch: But we’re also talking about heat entire fatigue from other external sources. For instance, the temperature of the road surface. The, conditions of the road that we’re driving over the amount of load that we’re carry different things like that.
87
00:14:53.250 –> 00:14:56.580
Andrew McCulloch: So, to go to our next slide please will expand on that a little more
88
00:15:06.360 –> 00:15:07.350
Andrew McCulloch: And at this point.
89
00:15:09.660 –> 00:15:10.860
Andrew McCulloch: It’s worth noting.
90
00:15:12.300 –> 00:15:19.050
Andrew McCulloch: That air loss occurrences increase as I’m sure everybody’s aware during the summer months.
91
00:15:19.890 –> 00:15:31.530
Andrew McCulloch: In fact, our data. Our experience shows that they increased by an average of 30 to 40% during the summer months, so that’s a fairly significant increase
92
00:15:32.130 –> 00:15:41.820
Andrew McCulloch: And the question becomes why, why did they increase by so much? What causes that increase during the summer months, versus cooler months in the winter?
93
00:15:43.830 –> 00:15:45.660
Andrew McCulloch: So, we go to the next slide.
94
00:15:48.030 –> 00:15:51.960
Andrew McCulloch: There’s several factors that cause that are the results of this.
95
00:15:53.970 –> 00:16:02.130
Andrew McCulloch: Number one is obviously in the summertime we have higher temperature, increase road surface temperature, and conditions.
96
00:16:03.180 –> 00:16:09.900
Andrew McCulloch: And this can be quite severe. Depending on the geographical area that that we’re operating in
97
00:16:10.500 –> 00:16:19.410
Andrew McCulloch: We’re operating down in South Texas in the Southern States during summer months, the road service can actually become extremely hot
98
00:16:19.980 –> 00:16:35.850
Andrew McCulloch: and again, heat and fatigue are both very detrimental to tires, old tires. So, we did increase road surface temperatures that can start to affect the tire itself and
99
00:16:37.080 –> 00:16:40.530
Andrew McCulloch: that can have a long-term effect on the tire’s performance.
100
00:16:41.550 –> 00:16:49.740
Andrew McCulloch: The other thing that we get our different driving habits and tendencies, and this is something that maybe we don’t necessarily think about
101
00:16:50.490 –> 00:17:00.450
Andrew McCulloch: Doesn’t come to mind immediately. But if you think about it’s actually a fairly important contributing factors during the summer months, we tend to be
102
00:17:00.840 –> 00:17:10.650
Andrew McCulloch: A little less cautious during the winter months, we tend to drive a little more cautiously, whether it’s snow or rain. We’re always cognizant of the fact
103
00:17:11.370 –> 00:17:22.560
Andrew McCulloch: Unconsciously that we have a slippery road surface that we have driving conditions that are maybe a little more perilous in the summertime. So, this tends to actually cause
104
00:17:22.920 –> 00:17:41.580
Andrew McCulloch: You can naturally be a little more cautious in the wintertime, and in cooler temperature driving. You tend to be more cautious to look down a little more carefully for road conditions and that type of thing. And that increased costs and level actually helps avoid
105
00:17:43.200 –> 00:17:58.980
Andrew McCulloch: Your tire issues and other issues are on the road. And finally, the last factor is loading and air pressure. Now loading in air pressure really are always a concern and always say a contributing factor to
106
00:18:00.000 –> 00:18:15.870
Andrew McCulloch: tire loss, but believe it or not, they tend to occur with a little more frequency during the summer months, and this is partly due to, you know, the volume of freight that’s moving around the country that seasonal
107
00:18:16.950 –> 00:18:31.710
Andrew McCulloch: And the number of trucks moving around and this sort of thing. I mean that that tends to hit peaks and valleys, highs and lows throughout the year in the summer months, typically tend to be their peak a period of time for this.
108
00:18:32.880 –> 00:18:33.330
Andrew McCulloch: So,
109
00:18:34.410 –> 00:18:35.850
Andrew McCulloch: We move to the next slide please.
110
00:18:39.870 –> 00:18:48.690
Andrew McCulloch: So how can we mitigate these losses. What can we do to reduce them. This goes back to the question Mark asked at the beginning of this presentation.
111
00:18:49.380 –> 00:19:06.180
Andrew McCulloch: And obviously we’re never going to eliminate all losses to some degree. Lots of us are going to occur. It’s just a natural part of life and it occurs and simple fact of life, but we can mitigate them we can practice risk management.
112
00:19:07.260 –> 00:19:13.800
Andrew McCulloch: Practices, which really will help reduce these losses and the more we can reduce them.
113
00:19:14.730 –> 00:19:21.300
Andrew McCulloch: The less we experience as far as total direct and indirect costs with respect to those losses.
114
00:19:21.810 –> 00:19:33.270
Andrew McCulloch: Most tire failures are the result of under inflation. We discussed what causes the sidewall of the tire to flex more generating heat and causing sidewall fatigue and failure.
115
00:19:33.870 –> 00:19:52.590
Andrew McCulloch: And that being the number one cause of tire failures. How can we change that? How can we help reduce those effects? And the answer is we can do that and it’s not that difficult. It requires a little bit of effort, but it’s relatively simple.
116
00:19:53.760 –> 00:19:57.540
Andrew McCulloch: So, next slide please. Will show you what can be done.
117
00:20:00.480 –> 00:20:20.940
Andrew McCulloch: Generally, a large portion of the roadside incidents or tire failures are the result of just really to two practices or two failures of practices. One is a failure to inspect the tires regularly and this is key and two is failing to maintain and replace those tires when necessary.
118
00:20:22.410 –> 00:20:36.510
Andrew McCulloch: To very simple facts, but both facts have a tremendous effect on the amount of the amount and type of roadside failures that we do experience. Next slide please.
119
00:20:39.420 –> 00:20:48.720
Andrew McCulloch: So, the first point is inspecting the tires. Well, we all know that it’s the federal requirement that the tires be inspected.
120
00:20:49.920 –> 00:21:08.220
Andrew McCulloch: As part of a pre-trip inspection. One of the things that needs to be done is inspecting the tires, checking the air pressure on those tires and I always tell. I always tell fleets, if you do nothing else with your tires, at least maintain correct air pressure, usually within inspection.
121
00:21:09.390 –> 00:21:18.990
Andrew McCulloch: Both externally and particularly internally with some of our offerings that we haven’t Michelin, there are six critical factors that you want to look for
122
00:21:19.620 –> 00:21:34.200
Andrew McCulloch: And we have them listed here in order of priority, obviously. Number one is low air pressure low air pressure condition will most likely cause tire failure, over time, but we also do want to look for high pressure scenarios.
123
00:21:35.400 –> 00:21:45.690
Andrew McCulloch: Missing valve caps are important. Why are they important because the lack of a valve cap can actually cause dirt, water contamination to get into a valid stem
124
00:21:46.140 –> 00:21:57.210
Andrew McCulloch: And effect of course ability to seal so it can actually cause residual error loss leaks, which lead back to our number one critical six factor low air pressure
125
00:21:57.960 –> 00:22:11.310
Andrew McCulloch: We also want to look for mismatched air pressure, and duels, and mismatched tread deaths, and irregular tire wear patterns which can tell us about other factors with respect to the vehicle that are affecting tire wear.
126
00:22:12.330 –> 00:22:15.000
Andrew McCulloch: Now, there are several
127
00:22:17.040 –> 00:22:25.440
Andrew McCulloch: products and services that are out there that are available. Several technologies that are available to help reduce this as well.
128
00:22:26.190 –> 00:22:38.760
Andrew McCulloch: But the most important fact is to do the inspection, to check the tires, to check the air pressures, and do you use an actual air pressure gauge
129
00:22:39.420 –> 00:22:59.370
Andrew McCulloch: Check the air pressures on the tires and make corrections and or repairs as necessary. If you find a tire that is a little low on air. And it’s the result of a of a nail or puncture or an object in the tire have it repaired have it fixed tend to it as soon as possible, obviously.
130
00:23:01.200 –> 00:23:02.160
Andrew McCulloch: Next slide please.
131
00:23:09.630 –> 00:23:22.380
Andrew McCulloch: Now what do you do if you experience a sudden loss of air pressure. And this is where we get into the NTSB, the National Highway Traffic Safety Associations.
132
00:23:25.980 –> 00:23:38.820
Andrew McCulloch: Statistic of 75,000 assets, a year. The sudden lots of air pressure, particularly in a steer tire can cause an accident and it can cause an accident, particularly if you have
133
00:23:39.480 –> 00:23:50.490
Andrew McCulloch: A driver, that’s unprepared or weather conditions that that increase the vulnerability or the instability of that vehicle on the road.
134
00:23:51.030 –> 00:24:01.380
Andrew McCulloch: But there are things that driver training that can be implemented to help reduce it when that happens, we know what’s going to happen, we can help them reduce the occurrences, but ultimately it’s
135
00:24:01.710 –> 00:24:13.170
Andrew McCulloch: A lot of severe pressure is going to happen. So, it’s important for drivers to be prepared for that and be familiar with what we need to do in the event of a sudden air loss or for
136
00:24:13.770 –> 00:24:20.700
Andrew McCulloch: A sudden air pressure loss in a tire. We have a video here a short video that actually does a very good job of explaining
137
00:24:21.510 –> 00:24:29.760
Andrew McCulloch: The behavior that’s necessary to counteract that scenario and the reasoning behind that scenario.
138
00:24:30.240 –> 00:24:40.980
Andrew McCulloch: Why does a tire lost cause an accident one tends to happen to the vehicle when air pressure loss occurs in a tire. So, if you could run that video for us.
139
00:24:41.910 –> 00:24:53.700
Andrew McCulloch: There’s one situation that many drivers dread one so varied and even some of the professional drivers believe it cannot be handled that situation while rare because the rapid loss of air in a tire. A blowout
140
00:24:58.890 –> 00:25:07.530
First, let’s take a look in slow motion exactly what happens when a tire loses air quickly because that’s all a blowout really is a tire goes flat in a hurry.
141
00:25:08.070 –> 00:25:16.920
When it does the front corner of the vehicle will drop creating a side force this side forth depends on such factors. This firewall and resistance and vehicle dynamics.
142
00:25:18.600 –> 00:25:26.160
Andrew McCulloch: Will continue to roll along the wheel and the depleted tire the driver needs to compensate for this new side force. What do you do to maintain control.
143
00:25:27.060 –> 00:25:37.620
Andrew McCulloch: The answer is under your right foot. No, not the rake in fact panic breaking is the worst possible thing you can do, taking your foot off the accelerator is the second worst
144
00:25:38.550 –> 00:25:48.930
Andrew McCulloch: The real solution is stepping on the accelerator getting power than the dry wheels mean maintaining control accelerator is your best answer, of course, pulling the rig to the side.
145
00:25:50.160 –> 00:25:58.350
OH, WAIT A MINUTE, YOU SAY, I don’t want to go faster. I want to stop right now. I’m going for the break and hard and you do that you may lose control.
146
00:26:00.150 –> 00:26:09.840
One of nature’s basic laws says an object going in one direction, such as a rig on a highway will keep moving in that direction, unless it’s acted on by a new side force in a different direction.
147
00:26:10.650 –> 00:26:26.160
In her diagram a size of the arrow represents the magnitude in the direction of these forces. The rapid or loss creates a new side force for unless the driver compensates for the side force the rig will move in a new direction by stepping on the accelerator. The driver starts to compensate
148
00:26:27.270 –> 00:26:30.690
It completes the compensation by making a small steering correction.
149
00:26:33.270 –> 00:26:40.200
If you think about it, you deal with these external side forces all the time when you drive, especially in cross winds are some high crown roads.
150
00:26:40.950 –> 00:26:47.070
All you do is step on the accelerator and correct with the steering wheel. There’s no difference when a steer tire loses air.
151
00:26:47.820 –> 00:27:03.000
When the tire goes flat, a new side force begins acting on the rig. By stepping on the accelerator, making small steering corrections and driving your lane you maintain control of your rig then choose when and where to slow down and safely pull off to the side of the road.
152
00:27:07.830 –> 00:27:08.250
Charles Whatley: Thank you.
153
00:27:10.440 –> 00:27:20.190
Andrew McCulloch: That’s, that’s an excellent video that really does a good job of explaining the type of behavior that we can implement to
154
00:27:20.670 –> 00:27:38.190
Andrew McCulloch: To reduce the chances of an accident or crash in the event of a rapid hair loss. So, we can boil that down to just three basic steps when it suddenly or loss occurs when you’re driving. Number one is do not step on the brake.
155
00:27:39.420 –> 00:27:52.260
Andrew McCulloch: Instead, just ease into the throttle a bit we say increase acceleration. That doesn’t mean you know a put the accelerator the floor, but we want to increase acceleration, just enough to
156
00:27:53.100 –> 00:28:01.950
Andrew McCulloch: Lessen the cross loader cross force that flat tire, causing on the vehicle and then maintain steering correction.
157
00:28:02.340 –> 00:28:08.910
Andrew McCulloch: So, you’re going to gradually step on the accelerator and gradually correct for that cross force to keep the vehicle in a forward.
158
00:28:09.480 –> 00:28:16.830
Andrew McCulloch: Straight line momentum position. And at that point, you then pull over. As soon as it’s safe to do so.
159
00:28:17.550 –> 00:28:32.310
Andrew McCulloch: But having gained regain control of the vehicle. Following the tire failure is key. First, and that’s why you want to slightly increase your acceleration and correct your steering at that point you can then pull over one safe to do so.
160
00:28:33.390 –> 00:28:33.510
Andrew McCulloch: It.
161
00:28:33.840 –> 00:28:35.430
Mark Rhea: Looks like yeah and the hold on.
162
00:28:35.460 –> 00:28:35.970
Andrew McCulloch: Yeah, just
163
00:28:36.030 –> 00:28:37.530
Andrew McCulloch: Just a quick comment up
164
00:28:38.130 –> 00:28:51.900
Mark Rhea: I’m looking at this and I’m thinking, this would certainly be a fantastic opportunity to have a two-way discussion with your driving staff, what, what have you observed. And what would you do
165
00:28:53.070 –> 00:28:54.450
Mark Rhea: If you
166
00:28:55.950 –> 00:29:07.620
Mark Rhea: Have a sudden air loss either the passenger side or the driver side, just as experiment I asked my neighbor yesterday, what would he do if he was driving his pickup and had a
167
00:29:08.370 –> 00:29:20.910
Mark Rhea: passenger side steering tire blow out. And his answer was to slam on the brakes and encounter steer the other way. I said, Okay, well that so that’s wrong, but
168
00:29:21.150 –> 00:29:23.130
Mark Rhea: That’s the normal answer so
169
00:29:23.310 –> 00:29:24.900
Mark Rhea: It would just appear that an
170
00:29:24.960 –> 00:29:26.280
Andrew McCulloch: Issue like this would
171
00:29:26.280 –> 00:29:27.300
Andrew McCulloch: Certainly be
172
00:29:27.300 –> 00:29:28.560
Mark Rhea: Beneficial to
173
00:29:29.130 –> 00:29:37.560
Mark Rhea: Do engage our driving staff on and have them exercise or simulate what they would do when something like this would happen.
174
00:29:40.200 –> 00:29:49.110
Andrew McCulloch: Right. That’s exactly right. I mean, it’s human nature to want to instinctively step on the brake pedal and rapidly recorrect
175
00:29:49.980 –> 00:30:01.950
Andrew McCulloch: With your steering and unfortunately that’s the worst thing you can do that is what tends to ultimately lead to a complete loss of control and an accident.
176
00:30:03.930 –> 00:30:07.020
Andrew McCulloch: So, it is although it’s your first instinct to do it.
177
00:30:08.100 –> 00:30:22.650
Andrew McCulloch: It’s really the worst thing you can do. And the best way to overcome that instinct is to practice it to practice getting used to applying the throttle slightly correcting for your
178
00:30:23.700 –> 00:30:32.850
Andrew McCulloch: Your directional instability gradually and you want to practice it enough so that when and if that ultimately does occur.
179
00:30:33.900 –> 00:30:40.680
Andrew McCulloch: It’s becoming grained in you as a driver enough that you can instinctively then
180
00:30:41.700 –> 00:30:48.240
Andrew McCulloch: make those corrective actions without having to panic or suddenly. Think about it. You understand makes sense.
181
00:30:48.720 –> 00:30:49.260
Absolutely.
182
00:30:50.580 –> 00:30:55.560
Andrew McCulloch: So have a conversation with your driver over it.
183
00:30:56.670 –> 00:31:10.380
Andrew McCulloch: But practicing for those events helps as well and can help drivers, be a lot more defensive and prepared when it comes to dealing with a rapid air loss situation.
184
00:31:11.520 –> 00:31:26.370
Andrew McCulloch: So, by doing this we ultimately help reduce the number of accidents on the road which ultimately reduces direct and indirect costs of a tire failure as well.
185
00:31:29.280 –> 00:31:32.880
Andrew McCulloch: And we do have quickly go to the next slide.
186
00:31:37.440 –> 00:31:44.430
Andrew McCulloch: Important thing to remember is, you know, many drivers will try to limp home on
187
00:31:45.540 –> 00:31:49.800
Andrew McCulloch: On a flat and that you don’t want to do
188
00:31:51.030 –> 00:31:57.420
Andrew McCulloch: For several different reasons. Well, number one, it’s a federal violation of CSA regulations to drive on a flat tire.
189
00:31:58.770 –> 00:32:04.140
Andrew McCulloch: But more importantly, you want to pull off the road as soon as it’s safely possible.
190
00:32:05.010 –> 00:32:17.220
Andrew McCulloch: That’s key. The other thing is, you know, if you have a failure in the tire. Let’s see, in your drive. Position your trailer position where you have a dual tire together and you have a failure on one tire.
191
00:32:18.390 –> 00:32:23.220
Andrew McCulloch: That vehicle may very well still be able to roll down the road at a lower speed.
192
00:32:23.880 –> 00:32:32.730
Andrew McCulloch: But you don’t want to do that because ultimately with the failure of one tire in a dual position you’re putting additional load on that one surviving tire.
193
00:32:33.330 –> 00:32:40.170
Andrew McCulloch: And as you if you recall, we go back to our number one cause of ultimate tire failures.
194
00:32:40.920 –> 00:32:49.860
Andrew McCulloch: On your inflation and overloading. So, once you have a failure on a dual see an outside dual fails, you’re overloading the inner
195
00:32:50.400 –> 00:32:57.540
Andrew McCulloch: Half of that dual tire application. So again, that’s another reason that you don’t want to try and continue driving on it.
196
00:32:58.140 –> 00:33:14.400
Andrew McCulloch: The important thing is to get off the road as soon as safely possible. And that’s what we stress, make sure it’s as soon as it’s safe to do so not just for the driver, but for other drivers and around and others involved on in in the traffic flow that the vehicle is in.
197
00:33:15.600 –> 00:33:15.900
Andrew McCulloch: So,
198
00:33:17.190 –> 00:33:26.400
Andrew McCulloch: To that end, there are several technologies out there that can help us monitor or tires monitor our air pressures.
199
00:33:27.420 –> 00:33:37.530
Andrew McCulloch: Can help with the inspection process when it comes to inspecting tires looking for issues with them and checking the air pressure as well.
200
00:33:38.340 –> 00:33:51.480
Andrew McCulloch: And we do have a couple of a couples of individuals with us today, as you mentioned, from Michelin who are we’re a little more involved with those technologies than, than I am myself but
201
00:33:53.520 –> 00:33:59.700
Andrew McCulloch: They can, they can expand on some of those technologies. Some of them are Michelin specific, others are not.
202
00:34:00.450 –> 00:34:11.910
Andrew McCulloch: But the important thing is to do the inspection and maintain your air pressure and remember air pressure is critical, based on the load and conditions. You’re driving in so
203
00:34:12.450 –> 00:34:20.880
Andrew McCulloch: I you know I get many people that asked me many fleets last me well what air pressure should I be running on my trucks. What’s the ideal air pressure for me to run
204
00:34:21.510 –> 00:34:37.470
Andrew McCulloch: And that’s an excellent question and the answer is it depends. So, the real factor that determines the air pressure that you’re going to run is the load that you’re carrying the maximum load. Wait. Now obviously 80,000 pounds is the max. We can legally carry
205
00:34:39.120 –> 00:34:59.520
Andrew McCulloch: But each tire and each application has a different air pressure that’s recommended for the load that is carried on. And if you look at air pressure charts for whatever brand of tires that you’re carrying they will generally tell you what air pressure that tire needs to run
206
00:35:00.660 –> 00:35:03.000
Andrew McCulloch: For instance, of drive tire carrying
207
00:35:04.260 –> 00:35:12.930
Andrew McCulloch: A fully loaded. Typically, if you’re fully loaded. Most of the time that drive tire may recommend an air pressure of saying 105 psi.
208
00:35:14.160 –> 00:35:31.380
Andrew McCulloch: See your tires different again trailer tires also different. So, fleets will generally set up an air pressure standard for themselves. Typically, let’s say 105 for the steers 100 for the drives, they will maintain those air pressures as a fleet standard
209
00:35:32.880 –> 00:35:46.770
Andrew McCulloch: When does it become a concern. Well, ultimately an under inflated tire can be defined as a tire that has lost enough air pressure to the point where it’s only at 80% of the air pressure typically
210
00:35:47.790 –> 00:36:02.220
Andrew McCulloch: Run by the fleet. So, if our drive tires are normally the fleet standard of 100 psi for our drive tires. Once we get down to 80 psi that’s now considered a flat tire and that’s what we want to look for.
211
00:36:03.240 –> 00:36:13.950
Andrew McCulloch: That’s how we determine is the tire flat. Is it under inflated to the point where it’s going to start causing an issue. So, something for fleets to consider.
212
00:36:15.000 –> 00:36:22.290
Andrew McCulloch: You know what, what’s going to be their standard air pressure for steer tires, for drive tires, for trailer tires, and
213
00:36:23.850 –> 00:36:40.230
Andrew McCulloch: those are generally again determined by the load or the weight that the trucks will be carrying their maximum load, their maximum weight, and these can be found in the air pressure guidelines, and tables that are published by all tire manufacturers.
214
00:36:41.340 –> 00:36:47.160
Andrew McCulloch: You can talk to your tire manufacturer rep, you can talk to your engineering reps.
215
00:36:48.090 –> 00:37:03.240
Andrew McCulloch: internally within the fleet, it’s important to come up with a standardized air pressure for your tires and stick to that and use it as a guideline for determining whether tires are under inflated or whether they’re acceptably inflated.
216
00:37:05.340 –> 00:37:07.410
Andrew McCulloch: And I hope all this is making sense for everybody.
217
00:37:10.020 –> 00:37:26.910
Andrew McCulloch: That it’s a lot of it is, it’s just simple risk management maintenance looking after your tires, checking your pressures, being cognizant of road hazards, and issues on the road that can lead to tire failures.
218
00:37:28.680 –> 00:37:35.220
Andrew McCulloch: It’s really very simple but it’s surprising how often it tends to slip through our fingers so
219
00:37:37.140 –> 00:37:37.920
Andrew McCulloch: Typically
220
00:37:39.840 –> 00:37:40.320
Andrew McCulloch: Typically
221
00:37:41.040 –> 00:37:41.700
Andrew McCulloch: Sorry, go ahead.
222
00:37:42.090 –> 00:37:47.040
Mark Rhea: Well, I was just going to ask Bryan I know Bryan’s the services and solutions manager, if he
223
00:37:47.040 –> 00:37:54.870
Mark Rhea: Had any input on here, Charles on some technology innovations or things that are in the works out there.
224
00:37:55.440 –> 00:37:57.570
Bryan Dingler: I know Mark, I appreciate that. Some of the things, Andrew, thank you for going through the details here causing these failures.
225
00:37:57.840 –> 00:37:58.500
Bryan Dingler: And what he was saying is the inspection.
226
00:37:59.220 –> 00:38:21.000
Bryan Dingler: Most of the time your inspection is either being done on the trust of, you know, servicing dealer is easy to be done, just, you know, trust factor or it’s done by pen and paper or may
227
00:38:21.030 –> 00:38:22.080
Be done on your yard.
228
00:38:23.160 –> 00:38:26.790
Bryan Dingler: And again, it’s only as good as the information that’s good. It gets put in
229
00:38:27.240 –> 00:38:38.700
Bryan Dingler: And one of the things that Michelin has done over the last several years is really tried to become more of a solutions-based company. And part of that is trying to figure out where our fleets end up with, you know, some of the biggest headaches.
230
00:38:39.570 –> 00:38:48.930
Bryan Dingler: Namely, things like blow outs and roadside events. And so one of the things that we’ve noticed, especially with Michelin’s on call emergency roadside service, we started doing some research.
231
00:38:49.470 –> 00:38:58.050
Bryan Dingler: And realize that, you know, majority of our blow outs or tire failures were occurring within 50 to 75 miles of the yard.
232
00:38:59.310 –> 00:39:02.010
Bryan Dingler: To what that tells us is that tire’s flat when it left
233
00:39:03.240 –> 00:39:16.200
Bryan Dingler: And so, when you start going back and trying to follow up. It’s okay. Well, tell me about your maintenance program. Tell me about your air program. Tell me about higher inspections that are done. And a lot of times they’ll go back into a filing cabinet, and they’ll pull out a list of, you know,
234
00:39:17.100 –> 00:39:20.130
Bryan Dingler: You know, grease-stained inspection papers and
235
00:39:21.000 –> 00:39:33.030
Bryan Dingler: Being done with, you know, a tire gauge that may have not been calibrated since you know 1987 or we even have some of the old, you know, the old tried and true baseball bats.
236
00:39:33.300 –> 00:39:33.660
Andrew McCulloch: At do
237
00:39:33.750 –> 00:39:34.770
Andrew McCulloch: To check air pressures.
238
00:39:35.220 –> 00:39:39.630
Bryan Dingler: And so what we’ve developed is a digital
239
00:39:40.020 –> 00:39:41.520
Andrew McCulloch: Inspection platform.
240
00:39:41.850 –> 00:39:45.090
Bryan Dingler: This offer is called Tire Care, and we utilize it through.
241
00:39:46.410 –> 00:39:54.930
Bryan Dingler: Our Michelin dealers are. This is something that you guys can do on site at your own facilities, but basically what it does uses in digital tread def gauge,
242
00:39:55.410 –> 00:40:03.300
Bryan Dingler: A digital air pressure gauge, and a smart device Whether it’s something that you know an iPhone or an iPad or Android either one.
243
00:40:04.380 –> 00:40:18.180
Bryan Dingler: And you can do a full inspection on a tractor and or trailer in less than five minutes and it’s a very accurate and detailed inspection and if it’s something that’s remote. If you have a remote yard. This is something that you’re
244
00:40:19.380 –> 00:40:23.610
Bryan Dingler: Servicing dealer can provide for you and the reports are automatically generated
245
00:40:23.640 –> 00:40:24.840
Bryan Dingler: So, if you end up
246
00:40:25.920 –> 00:40:26.670
Bryan Dingler: Inspecting
247
00:40:26.730 –> 00:40:28.650
Bryan Dingler: Let’s say you have 30 vehicles on the yard.
248
00:40:29.730 –> 00:40:30.960
Bryan Dingler: This report will actually
249
00:40:31.470 –> 00:40:31.860
Andrew McCulloch: time
250
00:40:31.980 –> 00:40:32.700
Those critical
251
00:40:33.750 –> 00:40:52.230
Bryan Dingler: issues that Andrew was talking about and send that out to the servicing dealer and or to home base so they can be corrected. This information is invaluable because one, it helps prevent downtime. It also helps prevent blow outs and the information is actually stored for
252
00:40:53.430 –> 00:40:59.400
Bryan Dingler: almost indefinitely, but a very extended long period of time. So, you actually have track of your, of your inspections.
253
00:40:59.760 –> 00:41:09.690
Bryan Dingler: If you guys do happen to have an accident because of a blow out, you have some records recourse to say here’s our inspection process. And it’s a very, it’s a digital
254
00:41:11.130 –> 00:41:16.290
Bryan Dingler: Form that goes in shows the accuracy. So, you actually not going to get blamed for
255
00:41:16.320 –> 00:41:18.180
Andrew McCulloch: You know,
256
00:41:18.360 –> 00:41:26.460
Bryan Dingler: malpractices the wrong word but getting blamed for not inspecting or properly maintaining your vehicles. So this is a very
257
00:41:27.180 –> 00:41:36.570
Bryan Dingler: Popular offer that we’ve had for several years, but to tie into that Michelin has taken another step forward to try to help mitigate events that have been
258
00:41:37.110 –> 00:41:42.780
Bryan Dingler: On the road if you’re inspecting Andrew was talking about earlier, you know,
259
00:41:43.440 –> 00:41:48.330
Bryan Dingler: Many of these events occur because the tire was in properly maintained before you left.
260
00:41:48.570 –> 00:42:00.690
Bryan Dingler: Now, there’s a lot of this can actually happen on the road you pick up a nail, you end up having a valve cap or valve steam that is started to leak and there’s a lot of technology and Micheline has
261
00:42:00.900 –> 00:42:02.160
Andrew McCulloch: Started to develop
262
00:42:02.370 –> 00:42:08.700
Bryan Dingler: That will help alert the driver and the shop for home base wherever you guys are located.
263
00:42:09.840 –> 00:42:11.430
Bryan Dingler: Before the blow out actually
264
00:42:11.430 –> 00:42:11.910
Andrew McCulloch: Occurs.
265
00:42:12.180 –> 00:42:13.950
Bryan Dingler: I was going to let Charles kind of speak to this because
266
00:42:13.950 –> 00:42:21.540
Bryan Dingler: This is some of the newer technology that we put out and Charles that are connected mobility team and give us a little bit more information about how those work.
267
00:42:23.190 –> 00:42:24.330
Charles Whatley: Yep. Can everybody hear me okay
268
00:42:26.160 –> 00:42:26.730
Mark Rhea: Yes, sir.
269
00:42:27.270 –> 00:42:27.870
Charles Whatley: Okay, great.
270
00:42:28.920 –> 00:42:30.990
Charles Whatley: Yeah. And then, and then cut me off if I
271
00:42:30.990 –> 00:42:31.800
talk too much.
272
00:42:33.330 –> 00:42:45.660
Charles Whatley: You know, as you said, nothing can beat a good inspection and I love to use this, the simple example because there’s some things you know you are going to hit something on the road and depending on which segment. You’re in.
273
00:42:45.960 –> 00:42:46.200
Andrew McCulloch: That
274
00:42:46.470 –> 00:42:53.010
Charles Whatley: can’t be stopped. You’re going to hit that object in the road or you’re going to be on the case of your refuge or
275
00:42:53.310 –> 00:42:55.470
Charles Whatley: You’re going to the dump the landfill and you’re
276
00:42:55.980 –> 00:42:57.930
Charles Whatley: You know, being exposed to rhubarb and
277
00:42:58.800 –> 00:43:00.030
Charles Whatley: Chunks of bricks and things
278
00:43:00.840 –> 00:43:03.120
Charles Whatley: So, there is with every segment. There’s a
279
00:43:03.600 –> 00:43:07.680
Charles Whatley: Different. Different percentage of how often something is there that’s unavoidable.
280
00:43:08.370 –> 00:43:27.390
Charles Whatley: That still runs in the two to 3% range. The rest of them can be avoided with proper tire care and a really simple little example if we got there measure your tires right now and take a measurement and come back a year later and measure again there. The odds are there’s something wrong.
281
00:43:28.440 –> 00:43:40.080
Charles Whatley: If we do that in six months, we just doubled our chance of catching an error. We did that once a quarter and we just doubled it again. It says, as we found the
282
00:43:40.800 –> 00:43:49.410
Charles Whatley: The average time between inspections, a shorter, you get that the better your chances are the tires can be fine. If we go out there, measure your tires right now.
283
00:43:50.160 –> 00:43:55.290
Charles Whatley: Come in here. Have a sip of coffee, go back out, measure them again, chances are they’re going to be right where they were.
284
00:43:55.860 –> 00:44:04.890
Charles Whatley: And that’s what we want to say, the more you inspect the more you increase your chances of having that tire correctly inflated and catching any instances.
285
00:44:05.400 –> 00:44:17.490
Charles Whatley: So, inspections manual inspections are great, especially if they’re done by a trained professional with good digital tools, but the reaches a point where we’re doing them once quarter, we’re doing once a month we’re doing once a week.
286
00:44:18.420 –> 00:44:20.430
Andrew McCulloch: Once a day, twice a day that starts to get
287
00:44:20.520 –> 00:44:27.300
Charles Whatley: Very expensive and maybe not even possible to have someone doing manually. So, we have technology we have a sensor and
288
00:44:27.900 –> 00:44:34.680
Charles Whatley: There’s two types of sensors. The sensor that can go inside the tire, which is the one we really like, you know, we’re a bunch of scientists and engineers.
289
00:44:35.130 –> 00:44:44.970
Charles Whatley: And when we stick that sensor inside the tire. We’re capturing the temperature inside that tire. So, we are allowed to adjust the temperature, the pressure reading
290
00:44:45.480 –> 00:44:58.980
Charles Whatley: To a normalized reading with the temperature. What that allows me to do is, even though you get a little extra load on here your tires got hot because you’ve been driving all day. I can still look at that temperature adjusted to the normalized pressure
291
00:44:59.790 –> 00:45:02.040
Charles Whatley: And I can tell you if you’re losing air.
292
00:45:02.820 –> 00:45:09.060
Charles Whatley: Over any period of time, so we’re able to catch with the internal sensor we’re reading
293
00:45:09.120 –> 00:45:10.590
Charles Whatley: That thing every two minutes.
294
00:45:10.890 –> 00:45:20.700
Charles Whatley: And we are adjusting for temperature, and we can detect a leak long before you’d ever see it, especially the slow leaks and
295
00:45:21.750 –> 00:45:34.980
Charles Whatley: With the technology we actually put a display in the cabs, so you know you notify the driver. If, as soon as it starts to see that before it hits any you know 10% down 15% down 20% down, we tell the driver that
296
00:45:35.310 –> 00:45:36.690
Charles Whatley: You’re losing air in this tire.
297
00:45:37.410 –> 00:45:45.960
Charles Whatley: And allows them to take a preventative action with when they do get down to 10% off and we can start sending notices off to
298
00:45:46.860 –> 00:45:47.640
Charles Whatley: Text messages.
299
00:45:47.670 –> 00:45:48.720
Charles Whatley: Emails and such.
300
00:45:49.620 –> 00:45:51.510
Andrew McCulloch: There are so
301
00:45:51.540 –> 00:45:54.690
Charles Whatley: You know that the cream of the crop is sensor inside the tire.
302
00:45:55.290 –> 00:45:56.130
Andrew McCulloch: Display
303
00:45:56.790 –> 00:46:00.120
Charles Whatley: In the cab, and we have a
304
00:46:01.080 –> 00:46:02.280
Charles Whatley: SIM card in your truck.
305
00:46:02.520 –> 00:46:06.900
Charles Whatley: Which is constantly sending data to the cloud. And we’re keeping up all the data.
306
00:46:08.070 –> 00:46:16.170
Charles Whatley: Um, you know, you can back off that a little bit. And we have sensing stations which measure your tires. Every time we go by the sensors are in the tires.
307
00:46:16.710 –> 00:46:26.370
Charles Whatley: Every time you come home every time you fill up at that the gas pumps. We put sensing stations in. And so now we’re looking at measuring your, your tires, you know, a couple times a day.
308
00:46:27.060 –> 00:46:28.590
Andrew McCulloch: So, there’s, there’s the
309
00:46:28.680 –> 00:46:44.430
Charles Whatley: Technology and technology is getting better and better. These are battery operated and they run for three to five years. And so that the technology is there and we’re seeing some very, very positive results from the fleets that are running these
310
00:46:46.590 –> 00:46:47.700
Charles Whatley: And
311
00:46:48.030 –> 00:46:50.280
Mark Rhea: That’s, uh, that’s, that’s something you know the
312
00:46:50.340 –> 00:46:50.820
Andrew McCulloch: The
313
00:46:50.940 –> 00:46:52.260
Mark Rhea: The reality is when it’s
314
00:46:52.260 –> 00:47:02.400
Mark Rhea: 110 degrees, it’s pretty easy to talk yourself out of going out and manually checking tire pressures, so this this tip center is certainly some
315
00:47:03.090 –> 00:47:10.740
Mark Rhea: breakthrough technology. We’re going to have to keep rolling here. I don’t. I know we’ve got a lot of people that have some heartbreaks can go the next slide please.
316
00:47:14.340 –> 00:47:18.330
Mark Rhea: Okay, we do, I would like to make sure
317
00:47:19.470 –> 00:47:30.360
Mark Rhea: That that we are offering it free demonstration. A 30-minute demonstration for our online platform that can
318
00:47:31.710 –> 00:47:45.060
Mark Rhea: Assign these types of videos to your drivers to prepare them for the summer to make sure they understand what the reaction is the proper reaction in the event of a rapid air loss.
319
00:47:45.420 –> 00:48:03.420
Mark Rhea: As well as just familiarize themselves and make them aware of the reality of, you know, air loss problems and how to prevent those from experts that we’ve had on this panel from the Michelin company. So, next slide please.
320
00:48:05.220 –> 00:48:07.020
Mark Rhea: Here’s my contact
321
00:48:08.460 –> 00:48:24.750
Mark Rhea: Andy McCullough, and Brian, we couldn’t get Charles in there. I’m sure that that if they’re interested in some of that information that you offered, they can there’s a next slide is the poll question, if I’m not mistaken. Next slide.
322
00:48:26.280 –> 00:48:26.670
Mark Rhea: Yeah.
323
00:48:27.720 –> 00:48:33.180
Mark Rhea: If you’d like information about the Infinit-I Workforce Solutions.
324
00:48:33.450 –> 00:48:34.380
Andrew McCulloch: Just,
325
00:48:35.190 –> 00:48:35.760
Mark Rhea: Plop in
326
00:48:36.090 –> 00:48:40.710
Mark Rhea: A Yes. And we will contact you on the free demo offer if you’d like.
327
00:48:41.010 –> 00:48:42.930
Mark Rhea: A representative for Michelin to
328
00:48:42.930 –> 00:48:46.080
Mark Rhea: Contact you on some of the problems.
329
00:48:46.140 –> 00:48:47.970
Mark Rhea: You’re experiencing in the field.
330
00:48:48.360 –> 00:48:50.550
Mark Rhea: Some of the technology that’s out there.
331
00:48:51.720 –> 00:49:05.310
Mark Rhea: Are just some good old-fashioned advice on how to improve the bottom line for both direct and indirect costs. Just click the yes and a representative from Michelin will contact you accordingly.
332
00:49:05.820 –> 00:49:26.220
Mark Rhea: So again, the first question is, if you want to participate in the free demo for Infinit-I Workforce, which of course we have 1500 clients we do over 350,000 assignments per month. And if you want to include some specifics on air.
333
00:49:27.630 –> 00:49:28.230
Mark Rhea: Lost
334
00:49:28.260 –> 00:49:30.690
Mark Rhea: Problems and rapid air loss.
335
00:49:30.750 –> 00:49:32.580
Mark Rhea: Hit the rest will follow up with that.
336
00:49:32.670 –> 00:49:40.650
Mark Rhea: We do have a couple of questions on out of time. Let me see if there’s a question or two. Is there a recommended
337
00:49:41.160 –> 00:49:49.590
Mark Rhea: maintenance schedule for checking air pressure in tires. Charles you answered that, which is
338
00:49:50.250 –> 00:50:08.310
Mark Rhea: If you do it once a year, you’re going to have problems and you exponentially improve that by the frequency that you actually do a manual or a remote or use of the technology is that correct
339
00:50:09.330 –> 00:50:11.100
Charles Whatley: Absolutely very well stated
340
00:50:14.700 –> 00:50:28.290
Mark Rhea: It, we are out of time. I don’t want to impact anything else we’ve got some great questions. One of the comments was after regaining control on a steer tire blow out
341
00:50:28.770 –> 00:50:40.680
Mark Rhea: I use the trailer trolley valve to decrease my speed doing this. I did not damage the wheel or real and maintained control and stop safely. What are your thoughts.
342
00:50:42.840 –> 00:50:43.170
Mark Rhea: Any
343
00:50:43.620 –> 00:50:44.100
You could
344
00:50:45.990 –> 00:50:49.410
Andrew McCulloch: You could certainly you can certainly do that. But
345
00:50:51.090 –> 00:50:57.330
Andrew McCulloch: The real recommendation is to try and maintain your steering control and
346
00:50:58.620 –> 00:51:06.780
Andrew McCulloch: And slow the vehicle down gradually once you regain control to pull off the road at a safe location.
347
00:51:07.440 –> 00:51:17.460
Andrew McCulloch: So, and each circumstance is different, you know, tire failures occur for different reasons a occur on different wheel positions.
348
00:51:18.000 –> 00:51:34.470
Andrew McCulloch: And what maybe works in one wheel position failure may not be as effective in another, but the steps that we laid out are universal, that, will allow you to regain control of the vehicle, regardless of which we’ll position.
349
00:51:35.490 –> 00:51:46.320
Andrew McCulloch: Suffers of a rapid air loss in the tire, so that’s important thing to keep in mind. Those are generally universal steps that regardless of conditions or
350
00:51:47.310 –> 00:51:54.990
Andrew McCulloch: Application or wheel position that’s failed will be effective and regaining control the vehicle and allow you to pull over and stop.
351
00:51:56.310 –> 00:52:11.580
Mark Rhea: Fantastic apologize for the questions that we couldn’t get to about five minutes six minutes beyond. So we’re going to have to shut it off again. If you’d like some information or our want to talk about
352
00:52:12.600 –> 00:52:13.500
Mark Rhea: Some of yours.
353
00:52:13.620 –> 00:52:15.840
Mark Rhea: Speed how to speed impact.
354
00:52:16.080 –> 00:52:20.940
Mark Rhea: Your tire program hit yes or somebody permission and will contact you.
355
00:52:21.240 –> 00:52:23.130
Mark Rhea: If you’d like to take us up on Jays
356
00:52:23.160 –> 00:52:40.350
Mark Rhea: Offer for the for the free demonstration on Infinit-I online training to get this information out to the field for your drivers to avoid that rapid air loss that can transfer into a rapid vehicle loss of control, which we obviously
357
00:52:42.930 –> 00:52:52.740
Mark Rhea: Got to stay away from. So, I’m going to shut her down and wish everybody a happy journey. Thank you for all the people that participated
358
00:52:53.160 –> 00:52:58.350
Mark Rhea: And we’ll talk to you on break check later this month.
359
00:52:58.380 –> 00:52:58.950
Mark Rhea: We’ve got
360
00:52:59.040 –> 00:53:01.710
Mark Rhea: the CVSA promotion
361
00:53:01.770 –> 00:53:09.240
Mark Rhea: on safety on breaks coming up later this month. So, thank you very much. And we’ll talk to you next time. Thank you very much.
