How is it uneven? When you had it aligned did they adjst the camber/cast? Did you get a print out sheet with the tolerances and stuff?

over/under inflation? can lead to some pretty nasy wear.

no i never got a print out sheet it happened to the last pair of tires i had to it has the wires showing on the inside and almost perfect tread on the outside ait says it is to have 50 pounds in the tires so i put 50

Whoaaaaa 50psi? That sounds crazy high IIRC. I think mine are 30 psi. IIRC the spare in a J (donut) is 60 PSI. And if the inner tread is wearing before the outter your def. overinflating those bad boys.

What tires are you talking about? Are they low profile tires or just the regular tires on there?

A regular car tire only needs around 35 lbs of air. If these are low profile tires, I would run around 32 pounds or so. You will notice a softer ride too, although with 50 lbs. or air the middle of the tire should have wore down alot faster. Could be wrong though.

I would have the alignment checked, and ask to see a printout of the rear with the tolerances or something. I believe something might be off. But, the rear of a J is pretty hard to align as well from my understanding, given the setup that it has back there. It may not even be possible to set the camber at all. I could be completely wrong, I'm no expert but I have assisted with quite a few alignments.

your right. wild weasel had a good post about this awhile back about what wears on the tire mean. if you had it over inflated that means the middle of the tire would have more contact causing the middle to wear out much quicker. 50psi is alot for a tire. my 17s and 18s i only ran 35 tops. well my steelies only take up to 42psi max

i have lows and it did it to them they had 38 psi in them adn my steelies ahve 35psi in them and it is startign to do it to

juss because the number on the side of the tire says 50, that's the MAX pressure, you're tire pressure should be around 35psi FRONT AND REAR. and if you think that you're rear shocks are bad, it could be possible, but to check, do a JOUNCE & REBOUND test, which basically is, push down on your rear quarter panels above the shocks, and if your car jounces n rebounds more than 3 times, then you're shocks need to be replaced, check the fronts as well also. only reason i know this is because im goin to an automotive school and this is the stuff i've already learned. good luck man.

You are running too much air in your low-pros. Run about 32 in them. And just like the guy above me said, the tire inflation pressure on the sidewall of the tire is the MAXIMUM the tire can hold, not what you should run. If anyone ever has any questions as to what tire pressure to run, PM me or ask your local tire shop and they will even adjust the pressures accordingly for free.

have u had your tires rotated? because if they were in the front and wearing on the inside, and you got the car alligned then rotated them to ther rear, even though you rotated them and fixed the problem, they will keep wearing on the inside.

j- bodies have a natural camber out on the rear anyways. depending on the wear ( the same type and amount on both sides and it isnt excessive) im going to bank on the tires not being rotated enough.

i have found that on most j-bodies the fronts tend to wear on the outside shoulder and the rears on the inside shoulders. also, out the correct tire pressure in your tires. tell me what size you are running example 205/55R16 or P205/55R16. i'll try and find the correct pressure for you.

i will check the tire pressures on the inflation charts when im either at my house next or when im at work next (which will be tomorrow evening).

well i finally remembered to post up the tire pressure you should be running. it should be 36 PSI.

after talking about ur problem some more with my boss (who read all the posts), he told me that even the correct tire pressure is not your problem and that your alignment is just that far out of whack.

Here's one for ya since we're talking about abnormal tire wear... I have intentional negative camber up front (toe and caster in spec) but the outer edges are wearing... Should be inside with negative camber. Been that way since I got the car. Doesn't bother me any, but made the only guy I trust at the tire shop scratch his head.

I don't have an answer for that one right now, but I am on lunch and will be going back soon.. when I get off work I'll let you know what the guy at work says about that, that's freaking weird.. I was scratching my head as well.

Camber doesn't wear out tires, toe does. I run 2 degress of camber all summer long and never have inside wear because I run 0 to 1/16th of toe and rotate them every 6K miles roughly. Also I run 37psi in my fronts and 35 in the rear on 215/45R17 due to my inclination to hard turns to compensate for rollover. This is the hot(after driving for a while) pressure, I'd reccomend 35 in the front 32 in the rear when cold.

Only way you'll get inside wear in the rear is if allignment is off (both camber and toe) in the front and the tires are moved to the rear. J's don't have near enough toe or camber in the rear naturally to wear out tires.

I think the whole lot of you must be driving on roads with a big bow up in the middle.
