The P31 from Heidenau is a snow tire for classic cars, offering modern technical performance but with a mischievous retro look to equip small and light vehicles, micro-cars or "vintage" trailers. The tread pattern is “all-terrain” with large interlocking blocks and notched shoulders; grip is ensured on all types of roads including snow and mud. The angle and outer notches provide excellent grip in corners. The sidewalls are reinforced for optimal protection against shocks and scratches.
