The optimal tread with the stabilized center blocks and the solid shoulder ribs, along with the ideal siping placement, enhances the grip on dry, wet and winter weather surface conditions with additional biting edges. The stronger year round compound keeps the rubber flexibility in different temperatures, from warm summer to colder winter situations. The four groove placement enhances the hydroplaning resistance by eliminating water and slush from below the footprint, which further improves the wet and winter driving safety levels.
