now there's the reason right there...hot dogger...yep, cause my front tire have twice the tread left as my back tires...but all wore very even, which impresses me...I have new F1 's to break in on the Dragon next week, but they are a summer tire, so it may get interesting if I can't keep them heated up...driving style, air pressure, are the 2 biggies...I'd say the contis are a 35k-40K tire under normal driving habits, but whats normal in an SRT....
