Potenza is Bridgestone`s most technically advanced high performance tyre, engineered for the ultimate driving experience. Factory installed by the world`s most prestigious auto manufacturers, including Ferrari, Aston-Martin, Porsche, BMW and Audi. The New Dimension of Perfectly Balanced Wet and Dry Performance Inheriting the technology used in the Potenza RE050, the tyre chosen for high performance cars the world over, takes the driving experience to a new level of wet and dry performance. Reducing the Potenza RE050`s four main grooves down to three enables a larger block on the tyre`s outside edge. This, combined with the new "Multi-Performance Block" and "60� Slant Lug", enables improved handling and braking performance in both wet and dry conditions Semi Slick-Centre Rib - Slick-style centre rib improves the handling response of the steering center GUTT II Simulation Straight Grooves - With GUTT II Simulation the alignment, thickness and configuration of the straight rooves significantly reduce the rick of hydroplaning 60 angle Slanted Sipe - Block sipes are positioned at a 60 angle, with the same effect as the nose of an F1 racing car. Block rigidity has been optimised, improving both traction and braking performance Block and Click Combination - Lateral grooves improve traction and braking. This combined with slick area, reduces wear on the inside edge and guards against becoming unbalanced with the outside edge Multi-Performance Block - The outside block, which takes most of the load when cornering, has been enlarged and reinforced to improve both wet and dry handling
