Now available from HPI Racing are direct replacement tires for the Super Nitro RS4 kits. These tires provide good grip combined with extended life, and will fit any of our new "Super-size" Super Star Wheels, as well as the narrow "Super-size" wheels from Kyosho and other aftermarket companies. They will fit any Super Nitro RS4 kit and the Kyosho Super Ten. Racers will find that using these tires on the front of their cars with slightly softer tires in the rear will help their driving on slick surfaces.
