I have a 95SE and still happen to have my 15" stock 6-spoke aluminum wheels on it. The tires are 50 series.

Interestingly enough, my front comes in at 5-1/8" and the rear at 6-1/8". And I double-checked my measurements.

I only measured on the driver side. I didn't really think to check the other side. The tires were the same pressure at 34psi

I love my Contour to death, but my 'vette is still my #1 baby.
There's money to be made in racing. I should know. I put a lot of it there.
You can make a small fortune in racing. Start with a large one.
How fast do you want to go...how much money do you have?
You can fix a lot of things, but you can't fix stupid!
