Belted Gravix^™ low-profile 7.4″ x 4.0″ tires deliver game-changing performance on the track or in the wild. The directional tread pattern provides excellent traction and runs quieter than typical off-road tires. Lightweight belting in the carcass maintains the tire's shape for a larger contact patch, more grip, and responsive handling at any speed.. Gravix tires come pre-mounted to black chrome XRT^® wheels with an ultra-tough 8s-rated glue bead for the most extreme high-speed action. Sold as a left and right pair. Fits 24 mm splined hex, front or rear.
