The angled lateral grooves and zigzag sipe placement provide better traction, even in dry, wet, and snowy surfaces. This is achieved with the higher number of biting edges generated by the passengers. Stronger compound materials keep the tire flexible even in freezing temperatures. Hydro- and slush-planing is avoided, as the lateral grooves evacuate water and slush from the footprint. These improvements earned the tire its three mountain-peak and snowflake symbol, indicating its severe winter weather durability.
