New for the up and coming GT8 class are the foam tyres from Contact RC. From the collaboration with some shops and very active drivers in the GT8 category, are born the new GT8 foam tyres. They are also suitable for running on standard 1/8th Off Roaders on tarmac/asphalt. The tyres have a diameter of 103 mm and are mounted on Schumacher rim with industry standard 17mm hex, resistant to hard impacts. Two hardnesses, one for the front the 35sh and one for the rear the 25sh.
