Hi Jon, the Pirelli's are way stickier than these Dunlop's. Since it is so hot it is hard to give a good guess on the life. I have been getting about 6 - 8 months depending on how much I ride.
William, told me the Pirelli's were Laser straight, and the Dunlops were good as well but hard to compare a tire like a Pirelii with a Dunlop only because the Supermax is a dual compound tire. Most likely will go back to Pirelli....
I am not doing track days at all, but I am sure there guys in your area that do...wouldn't trust a take off from #-bay, but maybe check Craigslist ?
