The asymmetric ribbed tread design and the all season compound work together to upgrade the dry, wet and winter weather grip on the road surface. The tread design's optimal pattern enhances the number of biting edges gripping the road throughout the tire's performance, while the compound keeps the rubber flexibility in various weather conditions. The tread's circumferential grooves prevent hydroplaning. They disperse water and slush from below the footprint, avoiding hydroplaning and further improving the wet and winter weather performing safety.
