So far these tires have met all my expectations. They do seem to be wearing a lot longer and better than the Kumho's they replaced. That's considering they went through two intense days at Road America for a HPDE. Speaking of which, the tires communicated well, and provided huge grip for a street tire. Short of a dedicated R-compound or DOT legal slick, these tires are the top for dry grip; better yet these tires can also handle real wet days. My car is a fairly heavy, rear drive V8 and they griped the road with authority. I know they cost twice what several other brands cost in the Max performance category, but it seems like I'm getting twice the wear out of them for a car that does street and track. If you're a drifter looking for some tires to smoke up in an event, save your money and get something else cheap. If you're looking for a street tire that can handle its own at the racetrack, this is it.
