Uneven tire wear, where to take it?
My right rear tire is showing uneven wear on it. Is this a job for the dealer or is a good tire/alignment shop the best place to look into the problem?

Uneven wear alone is not enough information. Is it wearing only on on the outside, inside or down the middle.
I'll bet a dollar to a hole in a donut that your answer will be that it is wearing down the middle. If this is so, your problem is under inflation. You need to run 35PSI in the rear tires. If you are running even a litlle less than that, this is your problem. I've driven these cars close to a million miles including almost 100,000 in a 210 car and have experienced this. Believe me, run 35PSI in the rear and about 32 in the front. Good luck, |

Larry - I have always been under the impression that if it wears down the middle it is over inflated and if it wears on the outer edges it is under inflated.

Thanks for the response.
The wear is on the inside of the right rear tire. The wear is consistant, no stair stepping or anything. The outside of that tire has a little more wear than the others, but the inside is down to the wear marks. All the other tires are fine. I think the toe adjustment is out on that wheel. I run 32 Lbs (cold) at all corners. Larry. Why do you run the extra lbs in the rear? Shouldn't the extra lbs be on the axle with the most weight? Also wouldn't lower pressure on the front cause a little understeer at the limit? I don't mean to challenge, I have viewed a lot of your posts and respect your knowledge. |

Inside tire wear means that the wheel is toed out.
It should show up and be correctable through alignment. A good tech will xpect an answer and find it. Camber and/or bushing problems can confuse the simple toe measurement and are the answer if toe isn't the direct cause.

First check tire pressure. If the tire is underinflated then a inside wear will slowly compound to a devastating tread separation. If you have about 25 psi then it is probably your alignment unless it has been unerflated for quite a long time. But if you check the pressure and it only has about 20 psi then just fill it up with more air.
