Ultra-rugged Sledgehammer tires provides extreme traction and control for a variety of off-road terrain.

The tires' open block tread design clears mud and debris for unmatched traction in loose surfaces. Sledgehammer tires come pre-mounted to massive matte black XRT^™ wheels with an ultra-tough 8s-rated glue bead for the most extreme high-speed off-road action. Sold as a left and right pair. Fits 24 mm splined hex, front or rear.
