No person shall move on any public way any metal-tired vehicle or equipment having on the periphery of any wheel a block stud, flange, cleat, or spike or any other protuberance of any metal other than rubber which projects beyond the tread of the traction surface of the tire; provided, however, it shall be permissible to use tire chains of reasonable proportions upon any vehicle when required for safety because of snow, ice, mud or other conditions tending to cause a vehicle to skid.
