Tire cupping

I know this runs all over the map but just pulled my Michelin steers and replaced em with bridgestones ...Wel see what happens ....the michelins just plain wore out .
I won't buy anything Chinese or firestone tho.

 

What kind of “cupping” is it? A river wear (looks like a river along 1 or more ribs) is usually low tire pressure. A chop across multiple ribs is usually a loose suspension component. If just half of the diameter of the tire is wore off, then it’s possibly a bent rib or the bead of the tires weren’t set properly, tire seating issues are commonly caused by rust or corrosion around the bead seating area. Wheel bearing torque is a huge factor and can play a part in all of these patterns.
Keeping the tire balanced and rotated through out its life is a big factor. And your running conditions will set that.
In my case, we retorque our wheel bearings, check shock absorbers, and use a stud/rim alignment tool (hub pilot hubs/rims) at every tire change. We run a balance bead pack in every steer tire, make sure the air used is very dry, and we run them at the maximum tire pressure allowed for the tire. If we see odd wear or we have a driver handling complaint, we raise the axle and spin it to check for bent rim, or a loose or bent suspension component.

One thing is for sure, once a tire wear is started, it won’t go away. The only thing you can hope for is to find the problem before it gets the next set also.....

 

I’m with you on Chinese tires. But....
You won’t buy Firestones but put Bridgestones on?

 

Yeah
Firestone is to Bridgestone like Michelin is to BFG

 

I had a Volvo with Michelin XZA’s start cupping on the outside, “River Wear” as was mentioned before. It’s typical of an open shoulder tire and the only cure is to run it out. That tire lasted 196k. Replaced them with Bridgestone 283 Ecopia and they lasted 120k before they started doing the same thing. I am currently in a 2015 Cascadia with Bridgestone 283s and the right steer is showing signs of “River Wear”.

It happens on a lot of our trucks, new or old. Seems to be the right tire too, regardless of how new the shocks are, and the trucks always get aligned with new steers. I check tire pressure weekly and maintain a minimum 105 on the steers.

 

They were cheap ! Lol
Ill see how they do and if results arnt good ill cough up the cash for Michelins again .

 

I might get flamed but we have always ran name brand steers. But I got talked into a set of Ironman steer tires about 3 months ago for one of our trucks.So far it's been one of the best steer tires I've had,drives great and balanced out perfect.
