Lucky With A Tire

[SanMarMor]

I got luck with my tire. Just as I was pulling into the campground yesterday, I got a low pressure alarm on my tire monitors. After we parked and sat around a while, I looked over and the tire was completely flat. It wouldn't hold air either. This morning I took it off and found this on the backside. The outer rubber layer had separated and split, showing the cloth layer below. I'm glad I wasn't driving with it like this.

We have no idea how many curbs/holes in the road the transport driver has gone over on his delivery run.

Sounds like the door side tires wearing like you say have a bent axle or axle stub issues. A big rig trailer repair shop can fix you up with a alignment/new suspension pins and bushings if needed.

Wear patterns on a trailer will be different than our tow vehicles.

I looked at my tire more. There is definitely an impact spot right at the split. There is abrasions right where the split is. If it was the outside of the tire, I would have expected I got a curb or something, but on the inside, it would be a lot harder for something to hit the tire like that. Something must have though.

The tire that went flat was worn more than the others too, with feathering that would indicate alignment issues. So I checked the other end of that axle, and it doesn't show feathering. The front tire on the side of the flat (door side) is also worn more than both driver side tires. Both driver side tires look pretty good, much better than both door side. But the door side only has a small slide, and the driver side has a large slide plus the bedroom slide. The wear pattern is confusing to me.

Any thoughts?

This makes sense, I had a little low pressure before I left that morning, and topped it off before leaving. It was at the end of a two hour trip that it alarmed again.

New tires as soon as I get back, before our next trip.

This is the results of tubeless inner-liner failure.
The failure normally is caused by a hard shock to that area; debris left on the road, etc. The hard shock causes the tubeless liner to split slightly and the inner air pressure leaks out thru the other layers of rubber but doesn't get thru the outer sidewall layer.
This situation normally progresses very slowly, and is another good reason to check tires before and during each trip. The bubble starts very small, gets larder and larger, and will eventually pop, exposing carcass ply(ies).

That likely started out as a bubble due to Air getting through the inner liner of the tire but not the outer layer. It probably had a bubble like this one I had on inside but fortunately noticed while parked while doing my pretrip inspection. When I got home and dismounted the tire off the rim I was surprised to see the bubble remained in till I poked it with a pin!

6 year old Triangle. I was just about to replace them, I've been researching. This was the rear tire on the door side. The split was on the inside. Makes me leery about my two hour trip home.
