Tire wear question

[Matt]

I personally recommend the rearward cross for lifted 4x4 vehicles, especially ones like ours that are hard to keep the alignment within spec due to the types of lifts we run.

The rearward cross is the best at mitigating tire wear associated with alignments that are at the edge of their spec range by putting each tire at every point on the vehicle. So say your right-front camber is a bit off, well with the rearward cross a tire will only see that position 25% of the time whereas if you go with the x-pattern it will be there 50% of the time.

I used the tire wear as an excuse to say I needed the track bar LOL

I missed that it was rear tire, but if you cross, you put the inside sidewall on the outside.
If you have blackwall tires, may not be an issue. If one side is whitewall you will look funny......

lol... brain fart?

The outside tread is always the outside tread regardless of where you mount the tire on the vehicle.

The only way to change this is to dismount the tire and flip it over on the wheel

Edit: think about it.. does that mean if you cross the tires then you'll see the back of the wheel instead of the front?

It's not beyond possible man. Not from a load standpoint as much as a crab-walk standpoint. If the axle is being pulled too far to the driver side then the rear will try shifting back to the passenger side as you're driving to following the front (basically the vehicle always tries to "square" itself). Did the driver side tire wear more on the inner tread? (that would indicate the axle is trying to shift right while driving)

... i just don't see that being enough of an issue on these vehicles to cause noticeable wear after only 6k miles. Spinning the main drive tire (RR) on rocks while offroading seems a lot more probable to me.

BUT.. it's better safe than sorry, so i recommend you get that adjustable track bar *wink wink*

Nope all three other tires looked great as usual. Like I said these tires have been wearing perfectly even the entire time. So I'll go with off road damage on this one but the track bar is needed to fix the problem LOL

[Matt]

The track bar being too short limits proper flex and accelerates the offroad wear... (sounds good! order up that fix)

[Sal-XK]

It's rough country that makes the track bar?

Our Rear track bar for the WK Grand Cherokee (2005 and newer) gives you fine tune adjustability for your rear axle on lift at or over 2.5".

Ive always done the rearward cross every 6K and they are wearing wonderfully. Id say its from spinning em while wheeling. There is no camber adjustment in the rear and you say you didnt see the problem when it was moved from the front. Cross em up and see if it changes next time.
