Dunlop SP Winter Sport 3D DSST (Dunlop Self-Supporting Technology) tires are self-supporting run-flat Performance Winter / Snow tires developed for sports cars, coupes and sedans that come from the factory equipped with low profile tires mounted on large diameter alloy wheels. SP Winter Sport 3D DSST tires offer temporary extended mobility in the event a puncture allows complete pressure loss. They are designed to provide dry, wet and snow-covered road competence by delivering traction throughout winter's cold temperatures.
The SP Winter Sport 3D DSST utilizes Dunlop's reactive silica mixing process to enable its tread compound to provide high elasticity at low temperatures resulting in dependable grip in winter driving conditions. This compound is molded into a directional tread design that reduces the chances of hydroplaning and helps maintain good traction on wet and slush-covered roads. Three different types of high-density sipes define three distinct traction zones in one tire. The central tread blocks feature "pulling" sipes to provide traction while accelerating and braking, especially on ice and in snow. The intermediate blocks use high-amplitude sipes to enhance lateral stability and control in wet and slushy conditions. And finally, the 3D sipes in the shoulder blocks interlock to increase dry road stability and handling while continuing to offer the flexibility necessary to grip snow and ice. The SP Winter Sport 3D DSST tire's structure includes twin steel belts reinforced by Dunlop's JointLess Band (JLB) of nylon to optimize the contact patch and minimize tire growth at high speeds. DSST tires incorporate special sidewall reinforcements that support the weight of the vehicle even after sustaining air pressure losses that would render conventional tires unusable. Designed to be run on while flat for up to 50 miles at speeds up to 55 mph, DSST tires provide drivers temporary extended mobility and the opportunity to drive away from stormy weather and dangerous situations.
NOTE: DSST tires are only recommended for vehicles originally equipped with self-supporting run-flat tires and a tire pressure monitoring system.
The Dunlop SP Winter Sport 3D DSST winter / snow radials meet the industry's severe snow service requirements and are branded with the snowflake-on-the-mountain-symbol.
Install Dunlop SP Winter Sport 3D DSST tires in sets of four only.
Do not mix radial winter / snow tires with tires of other construction, size, ply rating or pattern type. Dunlop highly recommends fitment of four winter / snow tires of the same type and rating for optimum mud and snow traction as well as maintenance of vehicle handling characteristics.
El neumático SP Winter Sport 3D DSST (con tecnología Dunlop Self-Supporting Technology) de Dunlop pertenece a la categoría: Rendimiento Para Invierno y puede soportar el peso del vehículo sin la necesidad de aire. Fue desarrollado para autos deportivos, cupé y sedán, equipados con neumáticos de bajo perfil de fabrica y son montados en rines de aleación con diámetros grandes. El SP Winter Sport 3D DSST ofrece movilidad extendida temporal en caso de un pinchazo que permita la perdida de presión de aire. Han sido diseñadas para proporcionar tracción durante las temperaturas frías de invierno y sobre carreteras secas, mojadas y cubiertas con nieve.
Para un agarre de confianza en las condiciones de manejo presentes durante el invierno, el SP Winter Sport 3D DSST de Dunlop, utiliza un proceso de mezcla reactivo de sílice, que permite que la banda de rodamiento permanezca flexible a temperaturas bajas. Esta mezcla es moldeada en una banda de rodamiento con diseño direccional, que reduce el deslizamiento sobre agua (hydroplaning) y ayuda a mantener tracción en carreteras mojadas y con aguanieve. Tres tipos diferentes de pequeñas ranuras sobre los bloques o tacos, definen tres zonas distintivas de tracción del neumático. El segmento central de bloques posee pequeñas ranuras pulling que proporcionan tracción al acelerar o frenar, especialmente sobre hielo o nieve. El segmento intermedio de bloques utiliza pequeñas ranuras de gran amplitud, para aumentar la estabilidad lateral y control sobre carreteras mojadas o con aguanieve. Finalmente, las pequeñas ranuras 3D sobre los bloques en los hombros se cierran conjuntamente, para mejorar la maniobrabilidad y estabilidad sobre carreteras secas, a la vez de, continuar ofreciendo la flexibilidad necesaria para una tracción sobre hielo y nieve eficiente.
La estructura interna del SP Winter Sport 3D DSST incluye correas gemelas de acero reforzadas por capas de nilón sin juntas y con la tecnología de Dunlop JLB (JointLess Band, esta, optimiza el área de contacto, al disminuir su crecimiento a velocidades elevadas. Los neumáticos DSST incorporan refuerzos especiales en las paredes o flancos, que permiten que el neumático soporte el peso del vehículo, sin presión de aire luego de un pinchazo, situación que deja los neumáticos convencionales completamente inservibles. Han sido diseñados para permitir movilidad temporal extendida, dando la oportunidad de alejarse de climas tormentosos o situaciones peligrosas; pueden andar hasta 50 millas a una velocidad , no mayor de 55 mph.
NOTA: Los neumáticos DSST son recomendados solamente para vehículos equipados originalmente, con neumáticos rueda flat (soportan el peso del vehículo sin necesidad de aire) y sistemas de control de presión de aire.
El SP Winter Sport 3D DSST satisface los requisitos severos de la industria en relación a la nieve, y por eso, posee el símbolo “montaña/copo de nieve” (mountain/snowflake).
Instale el SP Winter Sport 3D DSST en grupo de cuatro solamente.
No combine neumáticos radiales de nieve con otro tipo de neumático (diferente cantidad de correas, tamaño, índice de velocidad, de carga o diferente diseño de la banda de rodamiento). Dunlop recomienda el uso de neumáticos de la misma fabricación, para obtener tracción máxima en lodo o nieve, a la vez de mantener la maniobrabilidad del vehículo.
