The tread design and the all season tire compound improve the tire's dry, wet and winter weather road gripping ability. The compound keeps its rubber flexibility, while the tread elements firmly grip the road surface throughout the year. The wide circumferential grooves prevent hydroplaning. They disperse water and slush from below the tire's footprint, enhancing the wet weather traction. As a result, the tire received its M+S rating, noting its capability to perform year round.
