First aftermarket tire for me but I tried to do a lot of research before I purchased and it definately paid off. All the holes I got stuck in before I plow right through with these tires. they suck in the sand but I didn't buy them for that. the XTR's ride smooth at low speeds and handle perfect with the stiff sidewalls. To be honest I really think the bike steers easier with these tires than with stock.
Well worth the money when you're tired of getting stuck.
