Thanks for the info. I'll go out right now and get a close up of the tires. Be right back!

 

Here are the pics. The tread lugs in back are higher than the ones in front making it choppy and roughy... Hope this helps a bit more.

 

Have you rotated them at all over the 8,000 miles?

 

I got them with 4k on them. Then I have put about 3-4k on them since I installed them.... I have had them for about 2.5 months...

 

I have the same problem with fronts only on stock Rubicon tires, except it's reversed, on 1 lug the front is higher than the rear. Went to Death Valley a lot last year, I'm guessing 500+ miles of washboard beat up the shocks pretty good. Probably buy some 5100s when my tires wear out.
