The Italian manufacturer GRP has created ROAR-approved belted pre-mounted tyres for 1/8 class racing, speed runs and high-speed bashers. The belted carcass helps prevent tyre expansion under high RPM conditions and offers an engineered tread pattern with great traction and stability under heavy load. The wheels mount on a standard 17mm hex and are ready to run out of the bag.
