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.

...In Florida we see a lot of rainy weather and again, but I have never lacked confidence that the RE050A would perform for me when I needed it, wet or dry...
The Bridgestone Potenza RE050A RFT was the OEM tire for my BMW 550i equipped with the sport package. I trust BMW to put the best or nearly best tire possible on one of their top of the line sports sedans and this tire has not disappointed me whatsoever. I am not an aggressive driver but I do drive very fast. Consequently, I need a tire that gives me confidence to push my car to its limits. The RE050A does just that. In Florida we see a lot of rainy weather and again, but I have never lacked confidence that the RE050A would perform for me when I needed it, wet or dry. BMW is one of the premier auto makers in the world and if they issue these tires as standard equipment, they do so because they know they're good enough for the Ultimate Driving Machine. So far I have no reason to disagree with them.

This is the stock tire for the BMW 135i. Generally I enjoy the tires. They grip very well in dry, and are good when wet as well. My previous car was a Subaru STI so the overall wet handling is not as great by comparison. I'm very happy with the noise levels too. However, my main complaint with the tires is how quickly I go through them, especially the rears. I'm not seeing more than 10-12K on them.

For an OEM tire, these were very sticky. I am very surprised I got 18.5k out of them before they were done. I did several track days and lots of spirited mountain road driving on them and they had awesome grip. They did begin to give up around 17k and it was harder to push them. I would probably buy them again, but the runflat combo on the MINIs is horrible. I am moving on to another max summer performance tire.

A Great performance tire hands down. Driver is BMW trained. Car is powerful and responsive with these performance tires. Tramlining only occurs due to poor road conditions. On Autobahn at 130mph these tires are firm and true. In mountainous curves we apply more acceleration not less. Always two hands on wheel and these tires provide instant reliable return. Looking only for even more capability in another Bridgestone or we remain with these. Rough ride is part of the package--its a Sportster after all! LOL

Incredible tire, impressive handling and grip. Some may say, Run Flat Tires are a bit noisy and are a little on the stiff side going over bumps, but mine have neither. Quiet ride, with the confidence of being able to drive 50 miles, and 50 mph on a flat tire, can't get any better. Although these are strictly Summer tires, i have a set of Winter wheels to extend the life.

...Having put about 25K miles on them, I have found the ride comfort to extremely poor! That alone is a sufficient reason for me to switch these out and never opt for these again...
Due to a poor experience with these tires, I'm switching to non RFTs. Having put about 25K miles on them, I have found the ride comfort to extremely poor! That alone is a sufficient reason for me to switch these out and never opt for these again. I've had RFTs on a Z4 before and they were certainly not as bad as these.

..."Car originally had a bubble with these tires so I had the dealer replace it before buying (used). One and half years later, another tire developed a bubble. The tire must be replaced if it bubbles." Note: There are no phrases related to comfort performance in this text to bold based on the given criteria...
Pros: Sidewall stiffness, dry performance, cornering, predictable, runs when flat.
Cons: Expensive, so-so wet traction, harsh ride, heavy, sidewalls are prone to bubbles at which point you must replace them.
Car originally had a bubble with these tires so I had the dealer replace it before buying (used). One and half years later, another tire developed a bubble. The tire must be replaced if it bubbles. I avoid all potholes and have never curbed the tires/wheels. Some of the major roads in NoVA can get bad, and some construction/repairs in the roads go across the entire roadway, so you cannot avoid some road imperfections. Unless the roads in your area are near perfect, avoid these overpriced tires.
Read the forums to see how many others have had these same issues. And that's only the ones who have actually taken the time to post.

These tires come OE on my 135is and they came OE on a Mazdaspeed6 I used to own but in non-RFT. Excellent dry traction and grip. Mediocre wet traction. Awful ride and noise (RFT or not). Tread wear is bad on both versions. They are about spent after 11,000 miles in both cases. For a RFT I would recommend the Michelin Pilot Sport PS2 ZP. Makes up for everything this tire lacks. Dry performance is about equal.

...the tires are just plain awful and the tread is gone after 7500 miles, in less than 6 months!...
OEM tires, I guess for the run flat feature (no spare, just a goo pump). I bought the car for SCCA Solo and spirited mountain driving. Since I’m new to this sport I didn’t notice the 140 TW rating... the tires are just plain awful and the tread is gone after 7500 miles, in less than 6 months! I hope to gain 2 seconds on the track simply by getting rid of these. They don’t hold on turns, they don’t give any confidence, and they are rough and noisy on the interstate.

Tread is wearing down to quickly and tires develop bubbles. Climate here is cool and wet and traffic congestion really does not allow me to get to more than 65 mph for short periods of time. Am not happy with these tires. Purchase other performance run flats but not these. Am going to replace them.

...With 24,000 miles, I need to replace the rear tires. No crazy driving or wheelspins...
As an OEM tire, the quality of this model leaves much to be desired. With 24,000 miles, I need to replace the rear tires. No crazy driving or wheelspins. I'd understand the short life if there was a ton of traction. However, every aspect of these tires is lackluster at best. BMW must have received a killer price in order to spec such a horrendous tire (esp for the M-sport package).
