To all you duro power grip enthusiast I believe your right with this tire for an excellent off road tire. I have not ridden on the street with it but off road its just bites and keeps going where I know the stocker would of left me stranded or the need for speed might of compensated but its more fun being a tractor. Installing this tire is pure Hell! I got the feeling I was actually going to end up using this tire on the dock for a boat bumper. 2 tire shops and no luck...I finally did what I didnt want to do and I skimmed the bead area with a dremel like tool on my drill. Barely took any rubber off but enough that when I went back to the tire guy it popped on with a loud bang and brought dirt down from the rafters. I definatly didnt compromise the tire in any way doing this as I was very light on the removal of rubber and made sure I went slow and even. Fits the bike excellent, looks excellent..just need a bigger rear sprocket as it is a taller tire so my gearing is taller. With a 50 tooth sprocket its way to high geared now. Going down a steep hill I had to ride the brakes where as before I could of used 1st gear with no brakes. Thinking going for a 60 tooth, as I am not looking for highway speeds. Had a chance to ride it in the snow and it grips excellent. Definatly got a few looks and had one person snap a picture of it!.So just thought I would share this review, hope it helps.
