Who has had their front tires wear on the inside edges and at what mileage?

I have seen quite a few C5's with this problem. I am wondering if the cars are misaligned in the factroy.

My tires are like this too. I just bought the car from my uncle one year ago with 16K miles. The tires have been doing this for some time. GM has come out with new alignment specs. The old specs made the front tires wear a certain way to get the effect of tire rotation(since we can't rotate our tires). GM has rethought the idea and come out with different specs. I don't know if this is the reason for our tire wear or not.

That's normal for the C5.

You must consider the fact that you are driving a performance car, and in order to get the high negative G-force numbers during cornering this performance car generates, it takes negative camber. Negative camber will wear tires on the inside edges during normal street and highway driving, especially runflats with their hard sidewalls. You can have it aligned so it won't wear the tires like what you describe, like I have, and still be within GM specs., although you will give up a little cornering ability.

Too bad you can't have the best of both worlds all in one alignment setting, but it jst doesn't work that way.

Typically the alignment from the factory leaves a little to be desired. While the inside edges are wearing on yours others are having the outside edges of the rear tires wearing. Mine were gone in 4K miles (no tread on the outer half of the tire with almost full tread on the inside). The dealer realigned the car and replaced both rear tires under warranty.

My first set was toast at 16K. Wearing on the inside.

The inside edges of my front tires started to cup at about 9,000 miles. I had the wheels aligned about 1,500 miles ago. After the alignment, the car seemed totally diffetent.

Tom:

Does "totally different" mean better or worse ?? :confused:

The factory specs will probably give everyone the best "street" tire ware, which means, point the tires straight ahead ( Zero toe in) and almost no camber ( less that -0.02 degrees) :D

For more agressive handeling, but more street tire ware you can go to at least -1.0 to -1.2 degrees at all 4 corners, but you can expect a lot more inside tire ware. :cool:

Thanks for all of your replies.

The front negative camber on my car was close to the max spec as delivered, and the inside of my front tires was showing more wear after about 15,000 miles. I had it realigned to get more into the middle of the spec range, and the fronts (replaced) are wearing more evenly, although not perfect. In theory, I gave up a little grip at the front end. In practice, I can't tell the difference.
If you go to non-runflat tires, the wear will be more even for any given degree of camber, because the sidewalls can flex more. I stayed with runflats because they are a bit safer, especially if you get a flat/blowout at speed. Your choice.

my C 6 wore out the first pair of front tires at 15000 miles and only on the inside edge of both tires. The second pair is about gone at 14000 miles and again, no wear except the the inside edge of both tires. Is there a cure. The dealer says it is not alignment, I wonder,wheel bearing allowing the tires to tow out at speed?
