I have the Grabber AT2's. They look AWESOME and seem to have really nice grip. My only worry is when airing them down to 20-25 lbs for off-roading. Man, they look so flat that I always wonder if they are going to "roll off" they wheel if give them too much stress. It may be a complete, newbie, irrational worry, but it still concerns me when I see others air down to 15-20 lbs and their tires (especially the Nittos) don't look any different due to the stiffer sidewalls.
