I have been running RE-11's have used up 7 sets, now what to get? tire rack has Firestone Tire for $500 a set of 4 with a descent looking tread pattern. Has anyone tried them? if not these, what should I get? Looking for maximum summer grip, don't care about cost, don't care about rain grip, or road noise, just want the strongest grip available at any price that is DOT that can be rated to run up to 165mph.
