So I bought this this jeep used about 4 months ago. Its an 09 JKUR, of course the dealer didn't know much about it as it came from Idaho. Anyway what I do know. It came with a spacer lift and its sitting on 33in Kelly Safari TSRs. I started to notice a shake around 45-60ish mph, not death wobble mind you just a shake. So I'm looking at my front tires and they are worn REALLY strange. The rears are wearing even just the fronts. Well anyway, I had them rotated today and the shake is gone but I am wondering what caused the uneven wearing and what I can do to prevent it. I took some pictures to see if the pros on here could figure it out. They will be on the post below. Thanks for your time

 

As you can see on this lug it's worn down quite a bit. The next one is different. Sorry about the numerous posts. My phone won't let me post multiple at a time

 

Here is another... The wear is less. It's like this in the middle of the tire as well... Any thoughts?

 

Also I have put wheel spacers on it.

 

Have you had the alignment checked? Not paying for an alignment, just thrown on the rack for a 'before' printout. If so, post the numbers.

You could also run through Planmans DW/shimmy diagnosis (stuck to the top of the Writeups area) to check for loose/worn components.

 

Thanks I will check it out! I was trying to take a picture of the whole tread to show how uneven it is but you can't really tell in the picture.

 

I noticed the wear the day I met you in the parking lot. sometimes a bad shock can cause that, maybe bad ball joints. It could also just be the tires are prone to uneven wear. I found proalign is the best place to get checked out and then Les schwabb on Brooks, followed by Les schwabb on broadway..

 

Awesome thanks J! I will check them out. Figured I would see who j&k customs used but I prefer recommendations from people I know. How was the trip?

 

If those are Goodyear MTR/K then I had the same bizzare wearing issues with that tire, along with many other issues like out of round, never balancing well, etc. I went from 35" MTR/K that needed to be rebalanced every year to Toyo 37" MT's that have had none of these issues. They have 25k miles on them never been rebalanced and smooth as silk.

Some tires are just bad tires, lol

 

Does it look like every other block is worn more? Looks like cupping to me. I had the same issue when got bigger tires with stock suspension and it disappeared when I got new suspension. It is easily corrected with tire rotation tires wear back to an even wear or having your shocks checked.
