What would you do? I have a brand new set of Diablos sitting in my garage, my rear PP is toast on the bike BUT the front PP looks great. Should I pop for a rear PP now...then the existing mounted front and replacement rear PP's will probably wear out together? A racer told me once that "I always change both tires"....that's making me hesitate, is that BS? Thanks you guys....Doyle (Raydog)
