K58 Snowtex The K58 Snowtex is characterized by its excellent properties on cold and wet roads. Due to the high-quality materials used in this winter tire, it is adapted to the weather conditions in winter and allows use over a wide temperature range. Its tread consists of a high-quality silica rubber compound, which is combined with special textile fibers to maximize road grip in cold and wet weather. The Heidenau winter tires have a roughened surface from the factory and can therefore be driven immediately without break-in time.
