I am looking for good tires for mountain riding on a XR400. I ride mostly off-road on technical rocky terrain. Durability is high priority as I don't want flats and would like reasonable wear on rocks. I ride occasionally on-road so DOT would be nice, but not if I have to sacrifice off-road performance for it. I have been looking at the Kenda K760 Trakmaster II as it seems like an aggressive DOT tire. Any Views?
