I rotated my tires today and as usual I did my inspection. My tires have about 20K on them now and have been wearing down perfectly even. Today I noticed my passenger side rear tire tread was uneven. It wore obviously more on the out side then it did on the inside. The inside nobs were visually much higher. Any ideas on what would cause that to happen? I rotate my tries every 6k I just move the front to the back no crisscrossing. When I moved it back there it was all even so I'm lost now at what could cause this in the rear. I do know my shock wasn't seated properly for some time but can't see how that caused it. Any ideas would be great I told the wife I might need the adjustable track bar now LOL
