Product Description: Developed from the popular A50 Macadam with re-engineered tread design. Increased tread depth in center of tire extends mileage approximately 30 percent. Tapered tread grooves more evenly distribute stress on the tread blocks to resist cupping. Wider transverse grooves evacuate water from the contact patch. Large; stable tread blocks minimize tread ``squirm`` for razor-sharp handling and precise steering. Reinforced casing adds stability. Advanced tread compound offers ideal balance of wet traction and rability. Tubeless or tube type. H or V rated.
