Rock Bumps are pin-style tires for 1.9 Sporty Mini competition, and this set of two is in the 4.25 size. The name recalls the Goose Bumps, a dirt and all-terrain tire in the JConcepts line. The large pin surface, along with horizontal and vertical connector bars, forms walls of grip that flex, pivot and conform to most terrain. The 4.25 overall diameter gives ample ground clearance. The narrow 1.5 carcass and contact patch concentrate pressure on each pin for strong traction. A large center lug starts the heavy lifting, and relief edges clear the nearest pins. Angular traction bars on the edges begin the sidewall transition to an open shield feature. The narrow carcass has continuous contour and major flex, so it conforms well to rocks, holes and bumps. Radial ribs and extra sidewall bars add support. Fits: Axial AX-10 Scorpion Crawler Axial SCX-10 II Axial SCX-10 II Deadbolt Axial SCX-10 II RTR Axial SCX-10 Scale Truck Axial Wraith 1.9
