Well I was going to get some nittos at xmas but i noticed my tires are dangerously slick right now and I have a nail in a tire so..I'm going to get a new set today or tomorrow whichever. I want whatever is best for performance and street to replace my stock tires. What is the best one I can get for the money and what size can I go up to? I just left a place that had a Kelly tire that is v rated 245/40/17. I think it's "40". He said it is just a little wider than what I have on right now. $100 a piece. What do you guys think of that?
