The Grabber is not an MT, it was actually designed for desert races. The lugs are actually quite deep. I've seen a few sets in person on an XJ and a Chevy truck. They look mean, but from what I've been reading, they are not that great.
Be careful they may charge you an arm and a leg for shipping plus you still need to pay to get them mounted and balanced. I would try giving town fair tire a call because they can pretty much get anything. I just picked up a set of 35x12.5x15 general grapper AT2s (slightly cheaper version of BFG ATs) from them for my trailer. The red label grabbers are their top of the line MT tire. For that price I would look into a set of Goodyear MTRs with kevlar. I have them on my rig now and they put to shame everything else thay i have run before including maxxis bighorns that I loved and BFG ATs.
