I put this tire on a recently revived 2003 XR250R that had been sitting for a couple years or so. I've taken several rides with it on terrain that varies from hard pack to sandstone to sand. This tire does well on all those surfaces (haven't tried mud yet), and seems to do especially well in sand. It is a uni-directional tire, and the center lugs are formed to almost act like paddles. I can go up a sandy hill from a dead stop with no problem, too bad the SX1 I bought for the front doesn't perform like this tire. Haven't seen how well it will wear, but I definitely recommend it so far to anyone that needs a knobby rear and is on a budget.
