I've lost two XZA3 steer tire, shoulder came off separating a strip

Hi there,

My tire is getting cut in the inside shoulder.

I've lost two steer-passenger side exactly same way n 1 year, they both were Michelins XZA3; 1st time the interior shoulder would start to separate from the tread, took while until it blown.

2nd time, is this one in the pictures. It had like 50k miles on it, plenty of ribs. Same thing, same pattern happened twice, same tire model, same position. But this time we lost a big chunk of the tire shoulder...

What would be causing this ? Tire failure? Twice? Same thing same position? I've had the front end aligned and inspected with Josam in Orlando, FL a month before. Everybody that looks the tire can swear that we've hit something really sharp, but it affects just the inner shoulder. Happening twice is too much to be coincidence isn't?

What would causing this?

Thanks,

Update

Thanks Matt, no as far as we remember, I didn't hit anything, nor the driver had driving into a shop with oil change pit...On the top of that, I consider Travel Centers of America personnel, most of them, clueless, I wouldn't consider their opinion. But they said we hit something. I don't think so.

here is the pics

Yes exactly a split rib cut with knife; for some reason the pics that I uploaded never show-up. When it happened it was my driver in the truck and he said he didn't hit anything; Funny thing is in the same position, same tire size-model I had the same thing. I'm starting to believe it's a tire failure.

Truck was loaded and the closest repair was a TA, of course they refused to install my spare for obviously reasons and I had to install a brand new Bridgestone 280; driver is bringing the damaged tire back. I would take it to Michelin shop here and see what they say.

Thanks guys!

Please let us know what you found. Being the second tire, same problem makes me thing it maybe a turn stop out of adjustment, could be rubbing on something, frame, bolt, leaf spring etc when turning to lock rt or left.

Nothing was found and the alignment shop manager saw it and said he thinks it was nothing related with the front end. Coincidences or not not I've a Bridgestone in that position and lets see how what happens next.

A steer tire with a lower decoupler groove would help if this is the 2nd time it's happened. Heavy loads+heat and hard turns will do that to a steer tire.

If it is on the inside and people that have looked at it think you hit something, I would guess they are right. Do you ever go into a shop with a oil change pit in the floor? Is there any time you remember hitting anything?

Thanks for getting the pictures up. I have had the same thing happen with the same tire. I had it on the outside of my left steer after rubbing and jumping a curb at a parallel angle. I can't see any sidewall scuff marks in the pictures, and would find this much harder to do on the inside of the tire.

Please post what your locale Michelin says after looking at them.

Is it a split like rib to bead like it was cut with a knife?

had to xza 3's that did this took it in when I noticed it starting with less then 50% wear got the xza3+ paid a little over $500 out the door for both steer tires haven't seen any problems with new tire's.

I wasn't given any reason, but guessing it was a defect because there wasn't any argument from anyone.

Mike or Kevin Beckett would be your best source for a good answer on this. To me i'm leaning towards running over something to cut the rib off but I am guessing. Call md alignment and see if you could e-mail the pictures to them. If there have been issues with those tires they may know of them.

I just changed 2 xza3 steer tires cause of same thing. It wasn't as bad but I don't know if thy will warranty them cause a Michelin has to look at them first so I might have to fight them on this but I will have to pay 1111.14 well the company will pay then take it from me an I just don't think thy will warranty them but we will c. I would put up pic but don't c how to do it frm iPhone

I would also consider the possibility of changing lanes where road construction is taking place and you have one lane higher than the other. When you make this lane transition it pulls on that relief groove. I've never had this type of failure but have noticed cracks down in this same type groove on my Bridgestones. ''italic text''

They are recapped tires... check the date code and who did you buy them from...

Who ever put them on should have their shop shut down for good by DOT.
