Bridgestone Potenza S001 R Run Flat Car Tire - 255/40R18

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.

60º Slanted Lug

Block sipes are positioned at a 60º angle, with the same effect as the nose of an F1 racing car. Block rigidity has been optimized, improving both traction and braking performance.

GUTT II Simulation Straight Grooves

With GUTT II Simulation the alignment, thickness and configuration of the straight grooves significantly reduce the risk of hydroplaning.

SEMI-Slick Center Rib

Slick-style center rib improves the handling response of the steering center.

Block & Slick Combination

Lateral grooves improve traction and braking. The combined with slick areas reduces wear on the inside edge and guards against becoming unbalanced with the outside edge. Straight grooves positioned toward the inside edge, ensures water evacuation and improved wet performance, such as anti-hydroplaning. The position of the enlarged block ensures rigidity, and improves dry performance, such as dry handling.
