The inside tread of both front tires has worn prematurely on every set of tires I have owned. The rest of the tread wears evenly. I don't think it's an alignment problem since I keep my suspension aligned, and the car tracks straight with hands off the steering wheel. The car has 187,000 miles on it and is still all OEM; absolutely nothing has been replaced. The original Michelins were replaced at 35,000 miles due to this problem and I don't think the suspension components were worn out then. Still the problem persists and I want to get more miles out of my recently replace tires. I wonder if the stock alignment setting calls for negative camber which might explain the problem. Has anyone experienced this?

 

It is an alignment problem, more specifically, out-of-spec toe-in. Just because it tracks straight doesn't mean that the alignment isn't out of whack. Negative camber doesn't affect tire wear. Do you have spec sheets from your last alignment?

 

I believe is the toe as well...I just had an alignment on Monday and that was my problem...The camber angle was negative on mine...He said unless I get the adjustable cambers that come with the ball joint, he could not adjust the camber angle...The front and rear cambers will be coming soon...The total would have been around $80US...Take it in for a look...

 

Camber should be slightly negative in both the front and rear. The spec for the front is -10 minutes +/- 1 degree and the rear is -45 minutes, +/- 45 minutes.

 

Can't find the specs on my last alignment. Since the camber is not a factor, what are the specs for the toe?

 

Toe should be as close to 0 as possible. The spec is +/- 1/32".

 

Check for worn bushings on your control arms as well as setting the correct tire pressure. I would get an alignment done every time you replace tires or do any kind of suspension work.

 

I run the factory specs of 35 psi front, 33 psi rear. How do tell if the bushings are worn?
