Uneven tire wear?

Okay, so I did a spacer lift. Put in new shocks. Got an alignment. Now I am noticing uneven wear on my front tires. PSI is dead on.

But they are wearing like I am running them too high. (Losing tread in the center.) Caught it early and rotated them, same thing again.

I have talked to tire guys, but they may have been the same ones that did Ron White's van. SO, I thought why not ask the real experts at JeepForum.com?

What have I over looked? Feel free to state the obvious, I won't take offense.

You have too much psi in the tire causing the center to be higher than the side. The psi is max pressure for the tire, jeeps are lighter than many vehicles needing less psi.

Thanks, but that isn't it. I wasn't clear when I said the PSI is correct. I meant, I am running them light to compensate the weight.

Anyway, that would cause constant problems wouldn't it. Or at least cause the rear to wear that way as it is lighter than the front? Maybe not, but seems logical to me.

Thanks, but that can't be it. Only the front is wearing badly.

Do the chalk test on your tires. By that I mean mark across the tread with chalk and drive several feet. If the chalk is gone in the center of the tread, you have too much air. If the chalk is gone from the edges of the tire your pressure is too low.

I have 31's on my TJ and did the test to determine the right air pressure. I started at 35 psi and went down. I'm now riding with 30 psi in all tires and get excellent wear. And the ride aint bad either.

What else could it be? If they both have the same wear problem I wouldn't think both tires are defective. If the bad wear is even around the tire and in the center only I don't think it is suspension.

If the edges wear faster its under inflation, it the center wears faster its over inflation. Thats my thoughts anyway.

If the center is wearing out and the center alone.. you need to drop the pressure regardless of what you had it set at before. Lifting it changes steering angles, and caster measurements. Basically just chalk it up and lower the pressure till you have even wear

i agree, people are telling you what the probelm is and you keep ignoring it, just try it.

Exactly what tire pressure is in those tires? I hope it's not the same as the tire pressure that is molded onto the sidewall.
