How do and where do I go to fix my wheels

none right now :(
The tire size for an 18" wheel would be different... you are looking at a smaller sidewall (the second number) tire sizes break down like this (width)/(sidewall)/(rim size) On an 18" wheel, a 50 sidewall would be like a truck tire... you need to look for a 40 sidewall (or a bit less, say as low as a 30) You will find many options of tires then... on a 9.5 inch wheel, you can go to 285/40 easily, the most common size would be 275/40. 255/45 or 255/50 would be for a smaller wheel, say 8.5 inches wide, and the 50 series tire would be more popular on a 16 inch wheel, 45 series on a 17 inch... The later C4's have (mostly) 17" x 8.5 up front, and 17 x 9.5 in the rear, with 255/45/17 and 285/40/17 tires respectively.... Z51 cars and C4's from 88-92 with the 17" wheel had 275/40's on 17 x 9.5 wheels front and back. The 18" wheel on the rear of the C5 has 275/40/18 tires

Nono They make the C5 rims like this

17 x 9.5 with 56mm Offset (All Four)

They have a Chrome finish and will fit without adapters

They come out to 329$ Each (Us dollar)

Im going to stick with the 255/50 R17 route for now so Im able to rotate. But if the sidewall looks huge I'll reduce it without difficulty as (Your right) it is fairly easy to purchase tires in the 17" size with a lower profile.

(Of course this is when I run into some money again)

Again these are from Corvette America
