- horizontal tread elements on the inside of the tread are optimized for winter traction. - vertical elements, including 4 circumferential grooves, evacuate water for better traction. - two rows of side blocks work together under lateral force providing high rigidity for better dry performance. - Silica compound fights rolling resistance for longer mileage UTQG rating of 700 is among the highest in its class. - 3 dimensional sipes add tread block rigidity when new, and increased wet and snow traction over time.
