Belted Sledgehammer^® tires deliver game-changing stability and control whether you’re slinging mud or setting speed records. The wide, open-block tread design won’t clog up with dirt or debris and the lightweight belting maintains the tire’s shape for a larger contact patch, more grip, and responsive handling at any speed. At 8.4″ tall, the Sledgehammer’s increased diameter gives your X-Truck^™ a more powerful stance with even higher ground clearance. Sledgehammer tires come pre-mounted to massive 6-spoke black chrome X-Maxx wheels with an ultra-tough 8s-rated glue bead for the most extreme high-speed off-road action. Fits 24 mm splined hex, front or rear.
