The Sledgehammer's increased overall diameter provides additional ground clearance, while the open block tread design clears mud and debris for unmatched traction in loose surfaces. The tires are TSM^®-rated for high-speed and come pre-mounted with foam inserts and glued to 2.8″ dual-profile black Maxx^® wheels with a black beadlock-style ring. Fits 17 mm splined hex, front or rear.
