Dunlop SP Sport FastResponse DSST. FEATURES AND BENEFITS: Summer weather traction; Run flat tire model; High speed controllability; Quiet driving experience; . OVERVIEW: The Dunlop SP Sport FastResponse DSST (OE) is a high performance, summer tire made for passenger vehicles. This model is the original equipment tire of select vehicles.This tire model was manufactured with a run flat technology. The strengthened internal structure allows the tire to withstand the weight of the vehicle and its passengers, in case of air pressure loss. This enables the tire to securely perform for 50 miles up to 50 mph, once air pressure leaves the tire. In other words, the tire can still be driven on for limited temporary performance. The tire prevents the vehicle from being stand on the side of the road, allowing the tire to improve driving safety levels. At the same time, run flat tires should not be mounted on the same vehicle as regular ones.The asymmetric tread pattern and the durable rubber compound improve the tire's controllability. This tread pattern manages to firmly grip the road surface with extra biting edges. It increases the tire's road contact, boosting steering responsiveness and driving stability. The wide shoulder blocks and the special siping details help the tire have better cornering and braking throughout the performance. On the other hand, the strengthened structure keeps the ideal tire shape under the driving pressure affecting it, while the silica compound prevents heat build-up on the tread area. These elements significantly increase the tire's high speed performance, while the driver has full control over the vehicle.Excellent summer traction is promoted with this tire. The asymmetric tread pattern and the summer compound boost the tire's traction in dry and wet conditions. In other words, the optimized tread elements maintain close road contact, while the silica compound prevents heat accumulation along the tread area in warmer temperatures. Circumferential grooves help the tire prevent hydroplaning, by eliminating water and slush from the footprint.The Dunlop SP Sport FastResponse DSST (OE) offers a quiet and comfortable driving experience. The ideal tread design and the durable rubber compound enable the tire to keep close road contact, which reduces the tire's road and tread noise levels heard in the vehicle's cabin. This footprint channels airwaves through the footprint, preventing them from coming into contact with the tread elements and generating noise. As a result, the passengers can easily enjoy a quiet and comfortable performance.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.
