Response Pro tires are the ultimate in off-road racing performance. A taller profile increases side bite and offers better bump handling, while the ultra-soft compound sticks to the track surface. The outside row of spikes are contoured to provide just the right amount of side bite for smooth, predictable turn-in. Response Pro racing tires come pre-mounted and glued to 3.8″ dish wheels with race-tuned foam inserts. Wheels require 17 mm wheels hubs and nuts.
