The Optimo 727 tires by Hankook are designed for all-season performance on passenger cars. They feature a ribbed tread pattern with a continuous center rib that improves stability and provides consistent surface contact. Four circumferential grooves channel water away from the footprint to prevent hydroplaning. The specially formulated sidewall compound improves the durability of these tires by withstanding oxidization, abrasion, and aging. To absorb road shocks, these tires are fitted with coated, extra-wide, high tensile steel belts.
