I need new tires for my 1999 cavi with 195/65/r15 tires and stock rims. I would like to go to a little wider tire,but don't want it to look ridiculous and stick out past the fenders. What is the widest that can fit on stock rims but still not look bad? I want the same height that the tires are now if possible. thanks!!

Ben, take a look at this tire calculator and plug a few sizes in...

If you have the 6" wide alloy wheels (like the convertible or LS models), try plugging in sizes like 205/60/15 and 225/50/15. Those still say they'll work on a 6" rim and they're close to the same diameter. The 215/55/15 comes out a bit taller. There are several people here that run 225/50/16 tires on the 16" Z24 coupe wheels, but I've not heard of what people use on the 15's. Based on the calculator, I'd look at the 205/60/15 or the 225/55/15 with the latter being very close to stock diameter. That being said, the 225 is a lot of tire for a 6" rim, but it still falls within manufacturer guidelines.

sorry,forgot to mention the rims are 15" and are stock steel wheels.
