The stronger all season compound and the symmetric ribbed tread design improve the dry, wet and winter weather grip on the road surface. This combination enhances the year round grip on the road surface. In other words, the ribbed pattern and the rib edge sipes generate additional biting edges which firmly grip the road surface at all times. The all season compound optimizes the rubber flexibility in versatile temperatures, enhancing the versatile weather performing safety. The wider, circumferential grooves prevent hydroplaning by dispersing water and slush from the footprint, resulting in a secure wet weather performance.
