Their combination ensures a secure dry, wet and winter weather road gripping ability. The compound keeps its rubber flexibility all year round, from the heat of summer, to the cold winter weather temperatures. The tread elements, with the optimized siping detail, improve the gripping capability throughout the year. Furthermore, the tire is pinned for studs which can be added to the tire to improve its ice and snow gripping capability. The wide grooves and open shoulders avoid hydroplaning. They disperse water and slush from beneath the footprint to maintain the tire's constant contact with the road surface, offering an excellent year round driving safety.
