im getting 18s for my 06, and was wondering what size tire to run. im not looken for the tinny low pros, but somethen with some rubber so i can have fun.

 

18's with a lot of rubber are probably going to rub.

 

You are going to want the same roll out or total diameter so that your speedo is still right so in other words you will have to be lower profile than your stockers. Plus like Forty04 is right they will more than likely rub and could be pretty hard. PS what tire size do you have, I will give you the preferable size rubber to put on the 18" wheels. Good luck.
