Cupping on steer tires

In this order

Tire pressure
Shocks
Alignment
Bearings
Steering joints
Kingpins

Right side tends to wear a bit more due to road crown, proper rotation should solve that problem.

 

Every set of michelins ive driven always wears like that. No matter the truck. I just had that happen on this 2025 kw.. after 135k the passanger side started wearing like that.. shop put an alignment on and some proper bridgestones rather than crappy michelins.. your shop shoukd be doing the same. They need to change both tires as well after an alignment.. dont cut corners with steer tires it may cost you your life.

 

Yes it is legal, but that tire will continue to wear like that no matter what. An alignment wont fix it if they dont change the tires. Because it is out of balance now.. as a new driver i know it is hard to feel like anybody listens to you or cares about your opinion but i would really push the shop to put new tires on.. legal or not. Tell em to save those tires to throw on a trailer somewhere and or at the very least just get them off your steer axle... I really hate trucking companies that are cheap ##### and dont care about stuff like that. Typical bean counting mentality... Just do the best u can bro, we've all been there

 

I wouldn't even waste the time putting it on my trailer.

OP, that tire won't be legal long, and it's gonna drive like hell and get worse . I doubt it has 2 weeks before it has a flat spot across the tread.

 

That is exactly what happened to mine. I noticed it when walking around the truck while getting loaded one afternoon. Kept my eye on it. Not 2 weeks later the entire outer tread was gone. Another couple days wouldve had cords showing

 

I've never run anything but Michelin on my steer, and I've never seen a tire wear out like that on my truck.

I do start getting wear at the decoupler groove around 120-130k, but always figured it was due to the roads I run.

 

Along with the steer tire blow out how about everyone bunched up following to close, imagine if it was a passenger side blow out. Multiple fatalities most likely. Idiots

 

Rear axle shocks, not steer axle shocks.
