YET........Another Tire Wear Question
I tried to string this on two other forum tire wear threads, but got no answers hence a new thread.
I have a Y2K car that has both the front tires wearing on the INSIDE. The tires are oem Goodyear runflats and the car has Not been lowered. I run 30psi of air in the tires. It has 21K miles on it and is driven in a conservative mode without roadracing the on/off ramps of the interstates.
I am in the process of replacing the front tires and plan to correct the problem before the tires are replaced. I am not a tire front end type of guy, but I would like to know how to correct this problem from recurring when I replace the tires. Probably a setting away from the factory specs.......more negative camber??
I know a lot of these C5 cars have front end tire wear. I want to correct the problem before I end up with tires wearing to the cord on the inside. Others have had the problem. What has fixed them???
As far as those who badmouth the runflat tires, I'll say this. I saw
A-L-O-T of Corvettes at Carlisle this past weekend, and a quick glance thru the C5's showed the big majority of these cars all shod with Goodyear RUNFLAT tires. Yeah, they may ride a little rough but the flat insurance of being stranded is worth it. If I want a cushy ride, I'll move to the Caddy.

Good question. I just replaced all four GY Run Flats on my Y2K Coupe, and I had the same thing......excessive tire wear on the inside of both front tires. I understand that this is probably due to excessive negative camber settings, so I plan to have front end alignment done, and ask that camber be set to -1/8. Does that sound right to the forum front end experts?

The toe will also effect tire wear on the inside (or outside) as well. As most Vettes have very little toe-in the tendency is for the inside edges to wear.
When you find an alignment shop that is Vette friendly and competent, have them set the camber slightly more positive than recommended and the toe slightly more in as well.
Recognize when you do this you will slow down the Vette's response to steering inputs, and overall turning capability will be reduced (also known as the "no free lunch" syndrome).
Finally, there is one other thing you can do. Have a tire store "flip" the tires. This will put the worn tread on the outer edge and you can still run the tires in the same direction. The wheels will actually change sides though (i.e. flipped left front gets put on right front and vice versa). That way you get to keep the handling characteristics and maximize your tire wear at the same time.
HTH, and have a good one,
