Road surface, lean angle, type of riding. I've never
ever done a burnout (stupid), check psi and also have FOBO to monitor tires. I get 4,000/tire and change them 3X/year. My tires wear evenly from edge to edge, not just in the middle. We are equally puzzled how someone can get 10,000 + miles from a tire on such a fast and heavy
performance machine.
