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. The Sledgehammer's large diameter gives your Maxx a powerful stance with tall ground clearance. Sledgehammer tires come pre-mounted to black wheels with an ultra-tough glue bead for the most extreme high-speed off-road action. Fits 17 mm splined hex, front or rear.
