The Arctrac was developed for extreme winter conditions and various types of snow and ice. The angular 3D shoulder contours and stepped inner surface of the groove provide additional diagonal grip and stability, especially in snow. The intelligent tread construction means spike loss is reduced, ensuring their effectiveness. Tapered diagonal grooves give the best possible self-cleaning performance. Even in the coldest weather, the Arctrac guarantees excellent handling, a short braking path and fast acceleration.
