I have been riding bikes for 30 years and I have never had this happen before. I have 10500 miles on my bike and the front tire is slick. The back tire is almost gone too. I have always wore out two fronts to one back.I know some of you took off the stock tires and replaced them, but for the ones who wore out there stock tires, did this happen to you and what kind of miles did you get out of the set?
