Low-profile 7.4" x 4.0" Gravix race tires are built to run hard at the track or in the wild. The directional tread pattern runs quieter than traditional off-road tires with excellent traction and a thick center carcass to prevent ballooning at high speed. The tires come pre-assembled and glued to matte black XRT wheels with foam inserts. Sold as a left and right pair. Fits 24 mm splined hex, front or rear.
