POTENZA S001 RFT tyres feature an asymmetric design combining a large outboard shoulder, interlocking tread blocks and a central circumferential rib to enhance dry road steering response, high-speed stability and cornering precision. Bridgestone Run Flat Technology Tyres initially began as a social activity to enable vehicles for the physically disabled to be driven even after a loss of air pressure. Bridgestone aims for a safer and environment-friendly car society. With this goal in mind, Bridgestone will continue to improve its Run Flat Technology Tyres.<br /><br />Dry &amp; Wet Performance<br />Similar to POTENZA S001 (normal tyre), POTENZA S001 RFT provides excellent dry &amp; wet performance by an inner pattern with high wet performance and an outer pattern with high dry performance<br /><strong>Semi-Slick Center Rib</strong> The slick center rib enhances handling response of the center steering area<br /><strong>60&deg; Slant Sag</strong> Stereoscopic blocks in the F1 nose are distributed at60&deg;. Block rigidity is optimised, and both traction and brake performance were established<br /><strong>Combination of Block &amp; Slick</strong> Traction and brake performance are enhanced by grooves etched in a cross direction pattern. Furthermore, by adding slick regions, partial wear which tend to occur on inner sides is inhibited, thereby suppressing difference in wear between the inner and outer sides.<br /><strong>GUTT II Simulation / Straight Grooves</strong> To further enhance dry performance, three main grooves are included to create large blocks on the outer sides. Distribution, width, and shape of straight grooves are determined by simulation to ensure high hydroplaning performance<br /><strong>Multi-Performance Block</strong> Large blocks are created on the outer sides, which experience load during cornering, in order to increase rigidity. This improves handling under both dry and wet conditions<br /><strong>For Wet Performance </strong>Straight grooves are set in the inner side to ensure good drainage, promoting wet performance such as anti-hydroplaning.<br /><strong>For Dry Performance </strong>Block rigidity is ensured by distributing large blocks, promoting dry performance such as improved dry handling.
