I ride on the rode a bit. From my house to some trails. I also did the Paiute Trail in Utah, about 200 miles or more. also I have done many trail rides. I would estimate about 400-500 miles of trail riding on these and they have barely worn down past the top part of the tread. about 1/4 inch. Mind you that this part of the tread has much less surface area. There is still a ton of tread left

 

If I were racing GNCC I would go with the holeshots they grip like crazy they slide great and they are lighter but I ride trails coal pits and roads and I still race some so I went with the Razr IIs. They are a much meatier tire and they last a considerable amount longer than any Holeshot. Def worth the exta money cause they will last you forever espically if you dont ride on too much pavement.
