The tight arrangement of the sipes gives many biting edges to find a strong grip on ice- and snow-covered roads. The optimized grooves and the directional tread design clear slush and water from the footprint, improving traction. The tread area is pinned for studs. The main rib and many tread blocks deliver good surface contact, for a secure and reliable winter drive. The compound keeps the rubber flexible in cold temperatures, improving the overall performance.
