High Grip Moosgummireifen 42° Graupner 96350.42R The newly developed high-grip foam rubber tyres from GM-Racing have already been employed successfully at various races in 2005. At the Friedrichshafen Fair, held at the end of the 2005 season, seven of the top ten finalists - including the winner - placed their faith in the performance of the new GM-Racing foam rubber tyres. Particularly in"low-grip" conditions, the high-quality rubber offers a crucial advantage in terms of adhesion, combined with reduced rates of wear. The tyres are supplied already mounted on the familiar, proven "yellow" wheels, and are ground for accurate true-running. All wheels feature the standard commercial hexagon driver, and can therefore be used on any suitably equipped vehicle. The rear tyres are 30 mm wide, the frontones 26 mm wide. The 20° and 25° Shore types are the special indoor tyres with a unique ultra-soft rubber.
