Tire spin on rim

Mike Fender · 05-11-2013, 06:33 PM

2012 Avalanche 37'. Looking for possible cause why tire spun on the rim. While inspecting the tires I found small shreds of rubber around both sides of the rim. This is only tire I have balanced and if it wasn't for the metal tabs that hold the weights on the rim I never would of spotted the shredded rubbber. I had abt 75 lbs in all tires.

I'm guessing the bead was over-lubed when mounted and it slipped when hitting the brakes. In this case, the tire would need to be unmounted so you could clean the rim and bead, then try again.

I have never seen this happen. The wheel is the correct dia. for the tire? I wouldn't think it could be the amount of air - even a badly under inflated tire will stay on the bead until you push it sideways while backing or turning. Years ago, when the 16.5" 'camper special' wheels came out, people ran into trouble trying to mount 16.5" tires on 16" wheels. They would mount up and take air - but would pop off the rim when cornering under load. The previous poster mention too much lube on the bead - won't disagree, but it would have to be really lubed. JMHO-FWIW

Thanks. What I didn't mention was, that the tire is new. It was replaced/installed at Jacksonville Fla. From there driven to Pensacola, Fla. with no problem, then on to downtown New Orleans where I first saw the rubber shreds. Is it possible the trailer brake setting was set a little to high and being in downtown traffic using the brakes A LOT could have caused the tire to slip? thanks.

The tire should never slip, regardless of your brake setting.

Is it possible that the tire shop failed to put tire soap (lube) on the bead and their machine somehow shredded some rubber off of the bead when they mounted the tire? Just thinking out loud

I think jsmith has the right answer. if the tire size and wheel rim are the correct diameter you would not have this problem. if you think the brakes are causing this. I don't think that is true also. one the tries would skid first. or your trailer weights as much as a 747

but a sure way to check is mark the rim and side wall with some chalk hen go stomp on the brakes. If by some chance they move take that tire back it has aproblem with a broken bead!! good luck

You need to have the tire unmounted and inspected ASAP. That should never happen if indeed it did. BTW, who did the tire mounting in Jax?

Mike Fender, Howdy;

Ya need to cut down on the burn-outs

Sounds like the inside tire diameter is to great.

Update on tire... The point of purchase is American Tire. Prior to leaving New Orleans I inflated all tires to 80psi., and reduced the trailer brake setting by half a point. Since leaving New Orleans and driving to San Antonio, Texas there hasn't been any problem. Thanks for the advice and concern.

I'll tell you what happened - when I was younger I worked at a tire store. The kid who installed your tire on your wheel didn't use enough lube on the bead and the machine took a small chunk out from your bead. I've done it. Not a huge deal unless it leaks...

The theory of the machine grinding some of the rubber sounds good…unless the shavings the OP found weren't there before. OP didn't specify.

Good thought about tire shreds. I mounted the wheel on the trailer after having the tire mounted and I didn't see any rubber shavings on the tire. When I was pulling into the Rv park at New Orleans is when I smelled rubber cooking. After parking the rig that is when I found the rubber shreds on the tire. seeing and smelling prompted the thought that the tire slipped on the rim. Thanks.
