10k miles seems very low. do you see any excessive wear on the inner parts of the tire? i have 21" mpss when i got the car at 8900 miles. i recently changed it at ~16k miles as one of the front tires was showing inner wear, perhaps from being lowered with H&R springs. with my new set of tires, i'm hoping to at least get 15k miles as well. i also noticed that the fronts seem to wear more then the rears, perhaps too much aggressive driving style
