On my 01 I have some 33" BFG All Terrains and I was noticing some wear on the top portion of the sidewall. What could this possibly be from?

 

both inside and outside? ----> could be low tire pressure
one or the other -----> toe could be off

 

sounds like low pressure. how much psi you running ?

 

Is it on the inner tire surface?
33's in a stock truck might be rubbing on the inside.

 

The truck has a 2" level kit in front and if I go over speed bumps while turning or at full lock I think the outer portion of the tire rubs. I was running 26 psi in them because my tire guy calculated that and said it was the lowest I can go. So now the tires are back up to 42 psi but should they be raised? I haven't checked the back side of the tires but I am hoping it isn't bc of a bad alignment since I have had the truck aligned and everything was good.

The wear seems to just be on the top edge of the sidewall not on the outer edge of the rop of the tire

 

Does it get curbed often? Sounds like a rub somewhere to me, too...

 

That's what I was thinking too

 

so you were driving around with 26psi in them? i think you found your problem.

 

I was just checking to make sure that wear was because of that reason

 

Haha thats a good PSI for sand!
