Dunlop SP Winter Sport 3D DSST ROF. FEATURES AND BENEFITS: Winter weather traction; Run flat tire model; Vibration free drive; Precise steering responsiveness; Shorter braking distance; Rim protectors; . OVERVIEW: The Dunlop SP Winter Sport 3D DSST ROF is a performance and high performance, winter tire manufactured for passenger vehicles and SUVs.This model was made with Dunlop's Self-Supporting Technology which reinforces the tire's structure against the driving pressure. This enables the tire to maintain its ideal shape and to withstand the weight of the vehicle and its passengers after air pressure loss. In this manner, the tire can be driven on for 50 miles up to the speed of 50 mph once air pressure leaves the tire due to a puncture or other damage. This guarantees the tire's excellent performance as it will not leave the vehicle stranded on the side of the road once a damage occurs. These tires should not be mounted on the same vehicle together with regular tires, due to their heavier construction.The tire has excellent winter weather traction thanks to the three different siping details used in its design and the silica-based tire compound. The shoulder 3D sipes and the Active traction sipes enhance the road gripping ability, while the pulling sipes located on the center tread area improve the handling. As a result, the tire has received the three mountain peak and snowflake symbol that notes the tire's excellent performing and road gripping ability in severe winter weather. The directional tread pattern prevents hydroplaning situations by eliminating water from below the tire footprint. The better winter weather traction and hydroplaning resistance ensure a safer winter time driving experience.The model also offers excellent comfort levels. The internal structure's reinforced Jointless Band Technology places a spirally wrapped nylon cord on top of the steel belts to ensure exceptional durability. The tire does not deform under the driving pressure affecting it, as the internal structure maintains the optimal tire shape at all times. This allows the tire to closely follow the road surface, which lowers the road vibrations felt in the vehicle's cabin. The maintained tire shape also evenly spreads the driving pressure out across the tread area, which enhances the tread life and tire usability.The intermediate block sipes and the shoulder's interlocking 3D siping design, along with the specific bead seat system, boost the tire's handling. In other words, the tread design's road gripping ability and the tire's superb link between the tire and the rim ensures quick and precise steering responsiveness, excellent road feedback and maintained driving stability. The special Active Traction siping detail and the center tread's pulling sipes ensure a quick and safe braking ability. The tread pattern creates friction at the moment of braking, which shortens the braking distance significantly. The combination of these guarantees that the tire is effortless to control and remarkable braking in all weather, making it safer to drive in all winter conditions.The SP Winter Sport 3D DSST ROF is made with a specific sidewall design that protects the rims from accidental curb and other similar damages, by guarding the wheels at all times with the Max Flange Shield. 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.
