I have a slightly modifed 2010 2 door with Rubicon Muds. My front passenger tire is wearing funny. I have never seen anything like it. The nobbies (tread) are wearing at different hights, one up one down, one up one down in all four rows?? The tire is even accross. Just every other tread is up and down. My brothe rin law had the same issue?? Any thoughts??

 

is it cupping?

No just the nobbies are wearing funny. each tread on the tire are at different hights, like every other one. All other tires are fine! All four rows of tread are doing this???

 

After looking at your pic I think it is, all the way accross the tire?? Shock or Spring. Jeep seems to ride fine!

 

That happened to my dads goodyear wranglers on his TJ rubi. He never rotated the tires for 13000 miles and every other lug was worn down about 1cm more than the next. It made the tires obnoxiously loud. We never figured out exactly what caused it but its always good to rotate the tires to even things out.

 

Sounds exactly the same ecept it is just the one tire, and it is about a cm diffrence between each lug....

 

front or rear tire? Once they begin to wear unevenly they never correct.. If they are front check ball joints.. My fronts started to do it.. My lower ball joints were shot. My tops were still within reason. just a thought..

 

An alignment might not hurt? I would take it to the stealership and have them take a look under warranty.

 

Like the others have stated I would start with the easy stuff and check the alignment. Since it is only on one tire I would also look at the balance weights, sometimes those can come off and just that tire would be out of balance. If you catch it soon enough you may be able to rotate that tire to the rear and it won't cause as much noise and may wear better than it would in the front, but as stated, once its worn funny it probably won't ever wear 100% proper.

 

There have been several posts on this in the past. My own rubicon tires did this.

This particular tire wears weird unless you are religious about rotating them EVERY 3,000 miles.
