SSR SP1 Trail wheels adapt the iconic 5-spoke geometry of the legendary Professor SP1 for rugged off-road trucks and SUVs. Built as a heavy-duty 1-piece wheel, it reinforces the classic SP1 design with strengthened spoke connections engineered to withstand severe trail impacts and heavy load demands. This wheel fuses decades of JDM motorsport heritage with an aggressive, all-terrain stance, allowing overland and truck enthusiasts to conquer harsh environments without compromising on style.
