Of course their DOT, they wouldn't sell them if they weren't! I have SumoTumo HTR+ Summer Performance Tires 315/35/17. Maybe if they magically made an 18" Grand Sport ZR1 replica I would sell you my rear tires.
Kasey I do have tire rub when I have passengers in the back on the 315's but I didnt have fitment issues. The tire rub is practically non existant if it is just me in the car, and thats usually the way it is.
The tire rub noises Im hearing is something new with the stock wheels, I have no idea whats up yet. I'll work on the car on sunday most likely.
