I am going to buy a set of rear wheels and tires tomorrow. They are 15x9 rims with Hoosier 9.0-30.0-15 tires on them. I understand that these are some tall tires but I'm getting the set for $150. I just want to know if you guys think they will hurt my car a lot? I've never ran slicks. What would be a better size tire.My car is a 5 speed with 4.10 gears and I'm hoping to dyno around 320-350 range.
