help with tire number game !!!!

ok i have a 2008 z06 with 345/30/19 invos mounted on the stock wheels. i just got a killer deal on a ser of rear 18 inch wheels from a c5 z06 and im wanting to find a radial to mount as track tires. they have a set of 315/30/18 radials mounted now and everything clears fine. i am wanting to fit a taller tire that is closer to the height i am running now to give me more sidewall. i know everyone runs the front 17 inch wheel but these were dirt cheap and have to do better with a radial than the invos im running now.... and help here will b greatly appreciated.

This should help you find a tire with similar tire diameter quickly....from there, go see who makes tires in that size and find the manufacturer listed diameter. I say this because a 315/30-18 tire from two different tire manufacturers will have different diameters.
