I've had these tire on for about 25k and they almost look new still. They are not the best tires on the market, but they are not the most expensive either. I'm sure there are better tires out there but not for the price. I had Firestone's on before these and they were ok on dry pavement, but lousy on wet. These Kumho's stick like glue on dry corners, and are pretty good in the wet. When they do break loose, they are very predictable. I wouldn't hesitate to put another set on when these wear out.
