I have a 2008 WR250r with Dunlop 606s on it. Today on a unusual for me 70 mile black top ride i noticed when i got home that the front/leading edge of the front tire has little shavings like of rubber hanging off of it. I dropped my air pressure from 18lbs to 15 lbs the day before, would that do it? If it is just the 'nature of the beast' with these tires, i'll be ok with that, just don't want to further accelerate wear, un-even/cupped type wear, just because of air pressure. The tires have about 700-ish miles on them. Thank you very much for any advice. Mike.
