Tire wear question

[Sal-XK]

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

That's a strange one man... so within 6k miles the outer edge of the RR tire wore more than the inner edge?

Honestly, unless your having some other symptoms, i'd say it was just due to offroading.

Thats probably it I was spinning my tires a lot on those rocks. It should just wear back down without causing problems I'm guessing?

[Matt]

Yeah you should be good.

I would start doing a cross rotation though:
Backs straight to the front
Fronts cross to the rear

Check your alignment. Sounds like the camber may be off

Theres no camber adjustment on the rear tires.

If it was the front tire, the 100% alignment.... but:

I didn't notice anything unusual when I rotated the tire to the rear. I thought the tire rotation for all wheel drive was just front to rear? So your saying I was suppose to be crisscrossing just the front to the rear and move the rear straight up?

[Matt]

Yeah, you should be crossing the fronts when you bring them to the rear. The front tires get feathered from taking the loads while turning whereas the rear tires are just "following" the fronts. When you cross them to the rear it smooths out any feathering caused from being on the front.

[Sal-XK]

Ok I'll give that a try in about 6k miles

I agree with Matt. Try the crossing thing and see how that goes. Can't hurt that's for sure.

You speak of the track bar to bring the rear axle back to center. I know mine is off about an inch maybe??? I wonder if the rear axle being off caused the tire to wear like so because of weight distribution? I know you carry a lot of stuff in the back so could the weight have more pressure on the inside part of the tire b/c the rear axle was shifted to one side some? Probably not....IDK.
