I am getting some tire cupping or scaling (not sure of the correct term) on the front right tire. What could cause this? I just had an alignment done and it was good for a bit then it goes back to this. i want to fix it before I put new tires on the front and waste money. I am thinking a toe problem but what could cause this on one side.

I didn't know shocks could cause cupping thanks.

My buddy has BFG AT's on his truck and they cup like terrible. He assumed it was the tires but perhaps its the shocks.

Mine on the '02 are cupped badly, from being run under-inflated.

The shocks are less than a year old I thought that too but it did it before and after the new ones. Maybe it is underinflated. Are there any mechanical things I can look at??

Brake drag or driveline engagement, jack up the front and see if both tires spin freely. Spin the front driveshaft and hope the tires don't turn.

Aketay,
I went out and checked what you said and I can turn the front drive shaft and the tires do not rotate. Could it be a pitman or idler arm bad??

I had a bad case of cupping on the inside of both front wheels. Installed the cognito stabilizer kit to my stock idler and pitman arms and installed new tires--Seems to have solved the problem. THe stock parts are a piece of junk and i can't understand why they put these on. I believe that when these parts go bad, which they will surely do, the front tires toe in on braking which over time cause them to cup.
