Beautiful Sky Country

[redbaron]

Weather is beautiful, We are safe, God is good.

We had a blowout of the tag tire in the worst part of the road, but within 5 minutes we had a random tire company stop to help . They have MDOT blocking the lane for us and things are being handled.

I heard the pop and moved over as soon as I could . TPMs went to zero 2 minutes afterwards.

Wowza, glad all are okay. Gorgeous picture though

I'm sure all will ask, guessing no indication of something about to happen, it just happened.

glad your safe

I was talking on the phone (Bluetooth hands free) and heard a pop. I knew it was a tire. Was climbing the pass and tried to get over. I thought it was steer tire but turns out it was tag. Once I got as far over as guard rail would allow I saw the tire in mirror. I drove about 100 ft at 3mph and saw tire working itself off rim. Called it quits.

I had a 2 minute thought process to mentally come up with a plan and then TPMs went off….so much for that system.

I called my road side assistance and tire warranty (campers edge) and after about 10 minutes explaining why I don’t have a spare and they need to bring me a tire, I saw a road side truck repair pull in front of me.

We are 2 hrs into waiting for a tire to be brought and then should be good. I will update once this saga is over.

I also note that it was a Michelin! I just put six on ours. Can you tell what caused it?

I have had a terrible vibration. Thought it was steer tires. Had them road force balanced and tested and said no problems. I am now wondering if this tire was the problem. I am going to be doing a better check of the tire once it’s not in the traffic lane.

Tire dates are 18th week of 2021, so in the range to replace, but early imho to fail.

 

[Neemer]

It appears no damage to coach.

So the question is when you get new. Michelin or Toyo? I’ve lost faith in Michelin RV tires. Love them for cars. Not RV.

@redbaron , I know you enjoy moving along at relatively high speeds. Mind sharing what your speed was when it failed? Also had you noticed a higher temperature for that tire prior to the incident?

Ok, I thought we replaced tires not to maintain a schedule, but because they might give way.

At the time of the incident, I was doing 54mph. This was a 5% uphill grade, with outside temps of 80F and a total distance traveled from cold of 15 miles.

I heard the explosion and thought it was my front tire and was thinking how amazing the retrobands are. I was passing a semi on the uphill climb and had to let off gas to move over. As I moved lanes I could visually see the tag tire wobble and I allowed my speed to continue to drop naturally as I eased to the shoulder. I then drove about 100 ft, trying to get to the most visible spot when I noticed the tire working off the rim. I stopped there.

I mentioned earlier about a wobble. This started last year leaving Texas for glacier. At that time it was only at 68-70 and not below or above. On the return trip last year it became more pronounced below 60, but 62-68 was fine and that’s where I kept it.

I always assumed it was steer tires as it was felt in the steering, mirrors etc.

This winter I rotated the steering tires and checked them visually while off the coach. They looked great.

we left for Montana this year and noticed a terrible shimmy starting at 25 and staying strong until 62. It was so bad we couldn’t see out the mirrors or keep anything on the table without it bouncing off.

I took the coach to southern tire mart and had them test steering wheel balance. It was off and the rebalanced and did a road force test for runout. Told me tires are now perfect. The shimmy never left and I figured I had a hub, bad tire, or combination. 64 was tolerable.

After this blowout, the coach drives like a Mercedes. No wobble at all at any speed.

Lesson learned: you can’t tell which tire is bad by the feel. Any shimmy or speed related vibrations are potentially a tire giving up.

I will be putting 6 toyos on the rear before I return home.

Good to see you are ok and no damage to the coach. Be
Annoying shimmies - we had a soft shimmy and had tires inspected - all fine.
Finally decided to replace tires due to age and had all road balanced.
Learned something - road force balancing can show an issue that doesn’t appear on just a simple spin.
They showed me the spin balance on an inside 2 rear axle and it all looked good. Than they applied the road force and the shimmy became visible. We had a slightly bent wheel.
I am now a big believer in road force balancing, not just for the front wheels but all positions. Realizing that even if I think I know which wheel position it is coming from - I can be wrong, very wrong.

You mentioned TPMS going to zero 2 minutes after the fact, was this the integrated dash TPMS?

 

[redbaron]

Yes the gen 1 TPMs with the external sensors.

Not very happy with that result.
