The OEM Camaro tires are way too tall, but as posted above, a 245/45-18 tire is about spot on for looks, and within a half-inch of the OEM G-body diameter. [I found a matched set of 235/45-18 on Craigslist - these are almost an exact match to the 26.1" OEM diameter.] The 18" rims (steel and aluminum) are only 7-1/2" wide, but that may be about right to avoid body or frame mods. Locally, I've seen sets of the steelies go for $200 and aluminums for $300 - $500. The main benefit is that you can get into a 13" Corvette rotor no problem (others will tell us if 14" will fit).
By the way, have you seen the selection and availability of 14" and 15" tires lately?
