Bridgestone Potenza S007A RFT. FEATURES AND BENEFITS: Run flat tire model; Summer weather traction; Enhanced controllability; High speed performance; . OVERVIEW: The Bridgestone Potenza S007A RFT is a high performance, summer tire manufactured for passenger vehicles and SUVs.This model was made with Bridgestone's run flat technology. This technology reinforces the tire against the driving pressure, enabling the tire to withstand the weight of the vehicle and its passengers for a limited, temporary performance after air pressure loss. When air pressure leaves the tire due to a puncture or some other damage, the tire can still be driven on for 50 miles up to the speed of 50 mph. This prevents the vehicle from being stranded on the side of the road. Instead, it can safely arrive at a nearby location where the damaged tire can be taken care of. Run flat tires should not be mounted on the same vehicle with regular tire models.Summer weather traction is ensured with this model. The asymmetric, ribbed tread design and the durable summer compound work together to increase the dry and wet weather grip on the road surface. The optimal tread design's stabilized elements allow the tire to boost the surface grip. The summer compound keeps the rubber flexibility and prevents heat build-up in higher temperatures. The tread design features four circumferential grooves which disperse water from the footprint, optimizing the tire's surface contact. This promotes a stronger summer traction.The tire utilizes its optimized tread elements to improve its controllability. The notched center ribs closely follow the road surface, enhancing the steering responsiveness and the driving stability. As a result, the tire enhances the driver's control over the vehicle, improving the steering response time and accuracy. The stronger structure stabilizes the tire, boosting the tire's overall driving stability. The notched and siped footprint allows the tire to ensure a better braking capability. These tread elements generate friction at the moment of braking, significantly shortening the overall braking distance.The Potenza S007A RFT guarantees a safer high speed durability. The tire combines the structural stability and the heat-resistant compound to enable the tire's greatest high speed performance. The steel belt structure maintains the ideal tire shape under the high speed pressure, while the compound effectively prevents heat build-up across the tread area. This combination significantly increases the tire's high speed driving safety. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
