This very interesting as I didn't notice a treadwear number difference between the fronts and rears, I thought they were both 220. While I was at Discount Tire I had my buddy Ken look up tires for the Crossfire and as of right now, I could get a set of Hankooks for about $950 OTD or a set of BFG KDW2's for about $1100 and change, but like I said, that was as of right now and I say this because he told me the price is going to drop as time goes by, we shall see about that. I guess when it comes time to change out my tires I too will go with longer life rather than perf because by that time I will have already hit the Dragon with the car to see what its about it and will not need as much perf. Who knows, maybe I'll keep the car when the lease is up and stick with perf tires, probably BFG KWD2's, those are sweeeeeeeeeeeeeeet tires!
