The model is M+S rated for its superb dry, wet and winter weather performing capability. The tread pattern and the special tire compound work together to ensure a safer year round road gripping ability and performance. The high void ratio effectively disperses water and slush from below the tire footprint, preventing hydroplaning in the process. The tire's self-cleaning tread design also cleans out snow from between the tread elements to avoid the tread being blocked from its contact with the road surface.
