My cousin has a 78 Corvette and wants to go with bigger wheels & tires, question whats the biggest he could go with??

THANKS

He could probably go up to a 20" wheel if he wanted to. 17"s would probably be enough though.

Tell him to look for thing 17x8 with a 0mm offset 5x120.65. (call the wheel manufacturer to make sure they will clear the brakes) wrap them with some 255/45R18's for a wider footprint.

thank you for the help will have him call you when hes ready.

Sounds Good :)

Hello all, I am new to the forum as a member, have visited many times to get information.
I have a 2007 C6 Corvette convertible with a Lingenfelter SC package running around 600HP with about 500RWHP. I am currently running Michelin PSII's but am not very satisfied with performance below 60 degrees. This may just be the nature of the beast, but, if anyone has suggestions of something that might bite better in cooler weather I would love to hear the suggests. Thank you, I look forward to joining in the many discussions going on here.

Hello, I was also wondering what the max offset and size of rim and tire I can run on a 2004 C5 Coupe? I dont want it to stick out and there is no body kit.

Thanks!
