The Potenza RE050A RFT (Run-Flat Tire) is Bridgestone's Max Performance Summer run-flat tire developed exclusively for specific BMW, Ferrari, Mazda and MINI vehicles. The Potenza RE050A RFT is designed to provide temporary extended mobility for a distance of 50 miles at up to 50 mph even after a puncture has allowed complete air pressure loss. The Potenza RE050A RFT was developed to provide good traction along with responsive and predictable dry and wet road handling. It is not intended to be driven in near-freezing temperatures, through snow or on ice.
The Potenza RE050A RFT features a high-grip tread compound molded into an asymmetric tread design. Stable outboard shoulder elements, intermediate tread blocks and a continuous center rib provide responsive handling, high-speed stability and traction on dry roads, while circumferential and lateral tread grooves pump water out from under the tire's footprint to minimize hydroplaning and aid wet traction. A continuous rib adjacent to the inboard shoulder promotes even wear and resists inside wear generated by suspensions that specify negative camber alignment settings.
The tire's internal structure includes twin steel belts reinforced by spiral-wrapped nylon to stabilize the tread area and enhance handling, high-speed capability and ride quality. The structure of the Potenza RE050A RFT also features Bridgestone Side Support Run-Flat technology reinforced sidewalls to support the vehicle after a puncture causes a loss of air pressure.
Install Bridgestone Potenza RE050A RFT tires in sets of four only.
Due to the traction and handling capabilities of the Potenza RE050A RFT, Bridgestone recommends Potenza RE050A RFT tires be used in sets of four to provide the best handling characteristics and tire performance. Potenza RE050A RFT tires may NOT be mixed with other tire models, such as the Potenza RE050A I RFT or Potenza RE050A II RFT.
Though they cannot be labeled as run-flat tires, tires branded with MOExtended or MOE on their sidewalls offer run-flat-like characteristics by delivering limited temporary extended mobility after a puncture results in complete loss of air pressure. Because MOExtended or MOE tires do not have the same speed and distance endurance of conventional run-flat tires, they should not be substituted in any situation where a conventional run-flat tire is required. To confirm what your vehicle needs, check our Original Equipment tire listing for your year, make and model or see your vehicle owner's manual.

El neumático Potenza RE050A RFT pertenece a la categoría: Rendimiento Máximo Para Verano y fue desarrollado exclusivamente para modelos específicos de BMW, Ferrari, Mazda y MINI. Su diseño permite proporcionar movilidad temporal extendida; puede viajar 50 millas a una velocidad de hasta 50 mph sin necesidad de aire. El Potenza RE050A RFT fue desarrollado para proporcionar buena tracción, maniobrabilidad responsiva y predecible sobre superficies secas y mojadas. Como todo neumático de verano no fue diseñado para ser utilizado en temperaturas cercanas al nivel de congelación o superficies con hielo o nieve.
El Potenza RE050A RFT posee un compuesto de caucho de fuerte agarre moldeado en una banda de rodamiento con diseño asimétrico. Un segmento estable en los hombros, otro segmento intermedio con bloques o tacos y finalmente un segmento central continuo, proporcionan maniobrabilidad, estabilidad a velocidad elevada y tracción sobre superficies secas. Ranuras circunferenciales y laterales se encargan de sacar el agua en el punto de contacto con la carretera, disminuyendo el deslizamiento sobre agua (hydroplaning) y aumentando la tracción sobre superficies mojadas. Un segmento central continuo al lado del segmento del hombro interno proporciona un desgaste parejo y resiste el desgaste interno generado por el sistema de suspensión con ángulo comba/camber negativo.
La estructura interna incluye correas gemelas de acero reforzadas con nailon envuelto en espiral, para estabilizar la banda de rodamiento y mejorar maniobrabilidad, capacidad a velocidades elevadas y la calidad del andar. La estructura del Potenza RE050A RFT también utiliza la tecnología Side Support Run-Flat de Bridgestone, para reforzar las paredes o flancos y permitir soportar el peso del vehículo luego de una pérdida parcial o total de presión de aire.
Instale el Potenza RE050A RFT en grupos de cuatro solamente.
Debido a la capacidad de maniobrabilidad y tracción del Potenza RE050A RFT, Bridgestone recomienda instalarlo en grupos de cuatro para obtener las mejores características de maniobrabilidad y rendimiento, que el neumático puede ofrecer. Los neumáticos Potenza RE050A RFT NO deben ser mezclados con neumáticos de otros modelos, como por ejemplo, el Potenza RE050A I RFT o el Potenza RE050A II RFT.
A pesar que no pueden ser marcados como neumáticos (run-flat) rueda flat, los neumáticos MOExtended o MOE (marcado en el flanco) ofrecen características similares, al ofrecer movilidad temporal limitada luego de un pinchazo. Debido a que los neumáticos MOExtended o MOE no pueden ir a la misma velocidad o distancia de los neumáticos convencionales (run-flat), los MOExtended o MO, no deben nunca substituir a los (run-flat) cuando son requeridos específicamente. Para confirmar que neumático necesita su vehículo, verifique nuestro listado de neumáticos originales, de acuerdo al año, marca y modelo del vehículo o consulte el manual del propietario.
