This tread pattern can maintain close surface contact in winter, while the special compound keeps the rubber flexible in harsh and freezing temperatures. These elements work together to boost traction on ice- and snow-covered roads. At the same time, the tread and the winter compound improve the tire's performance in severe winter conditions. The optimized grooves prevent hydroplaning, by dispersing water and slush from the footprint. These grooves protect the tire from slipping on wet roads.
