MEDALLION ACP1 – All season PCR Tire:The best-of-the-best in every condition. The Medallion All-Season truly lives up to its name, providing the best possible grip in both summer and winter. Due to its V-shaped lateral grooves and two-wavy longitudinal grooves, it’s able to disperse water easily but also offer maximum grip in snow. The 3D-sipes in the tread enhance stiffness and maintains handling.
