LAUNCHING THE NEXTGENERATION RUN FLAT TECHNOLOGY TYRETHAT KEEPS YOU SAFE ALL THE TIME<br />Bridgestone recognises the importance of helping to raise the level of safety for motorists around the world and so has pursued ways to overcome the risks associated with punctures. These efforts have resulted in the revolutionary tyre technology known as Run Flat Technology (RFT). RFT tyres are specially constructed so that even without air, it can still maintain its shape and also the strength to support the weight of the vehicle, therefore continuing to work safely.<br />Even when a tyre suddenly loses air, the car can be safely driven without losing control<br /><br />Heat Control Technology<br />Drive in comfort even with tyre air loss<br />When tyres puncture, the sidewalls can suddenly warp and generate greater heat. The biggest challenge to maintaining or increasing Run Flat Technology tyre durability (after air pressure is lost) and enhancing riding comfort, is coping with heat generation. Bridgestone&rsquo;s heat control technology resolves this problem.<br />MORE COMFORTABLE RIDE<br />Performance in riding comfort comparable to normal tyre could be achieved<br />Test Conditions]Normal tyre (POTENZA S001): 245/40R18 97Y XLPrevious Runflat Technology tyre (POTENZA RE050 RFT): 245/40RF18 93WPOTENZA S001 RFT: 245/40RF18 93WTest load: 4.71kN Air pressure: 240kPa Testing method: Static load characteristics testingTestsite: Facilities located at Bridgestone Technical Center<br /><br />New Sidewall-Reinforced Rubber<br />Reduces friction occurring between carbon molecules when the tyre is loaded, thereby reducing heat generation.Compared with sidewall-reinforced rubber of previous Run Flat Technology tyres, NanoPro-TechTMcan reduce heat generation that occurs due to the deformation of tyre sidewalls during run-flat driving (when driving on tyres that have lost air pressure) by 50%<br />COOLING FINT<br />Cooling sidewall heat generated when driving on tyres that have lost air pressure.COOLING FINTM technology features protrusions, which face toward the center of the wheel on the surface of tyre sidewalls in order to create disturbances in the airflow and thereby cooling the tyre.
