I got almost 30K on those piece of crap SR-As. I roll on Bridgestone Dueler H/Ls now and I'm lovin' them! (04' SE KC) Plus the Badyears do not have a mileage warranty on them and the Bridgestones have 65K warranty on them. The ride is much smoother and much quiter. All you can hear now is the so-called "too much built-in engine noise".
