Set of two (2) Sand Buster front rib tires for the HPI Baja 5b. Now you can take your Baja 5B to the dunes and throw huge roosts of sand just like the real sand rails. Molded in HPIs exclusive M Compound, Sand Busters Rib fronts have a rib down the center of the tire to cut through the sand for stable steering.
