The Turanza EL400-02 RFT is Bridgestone’s Standard Touring All-Season self-supporting run-flat tire developed as Original Equipment (O.E.) for Lexus IS250C and IS350C models, as well as all-wheel drive Toyota Sienna* minivans as of the 2011 model year. The Turanza EL400-02 RFT is designed to combine temporary extended mobility (for a distance of at least 50 miles at up to 50 mph even after a puncture has allowed complete air pressure loss) with dry, wet and wintertime traction, even in light snow.
Turanza EL400-02 RFT tires feature an all-season rubber compound molded into a symmetric tread design with straight circumferential grooves to balance dry and wet road traction with noise comfort and hydroplaning resistance. The tire’s internal structure includes twin steel belts reinforced by spirally wrapped nylon to blend high-speed durability with uniform ride quality. The structure of the Turanza EL400-02 RFT features Bridgestone Side Support Run-Flat technology-reinforced sidewalls specifically tuned to support the vehicle in the case a puncture causes complete loss of air pressure.
*The P235/55RF18 99T-sized Turanza EL400-02 RFT developed for Toyota all-wheel drive Sienna minivans beginning with the 2011 model year is Bridgestone’s first run-flat tire to arrive in the U.S. that features their 3rd generation run-flat tire (3G RFT) technology. The 3G RFT tires are designed to offer almost the same riding comfort as conventional tires while continuing to provide temporary extended mobility in the event a puncture allows complete air loss. While Bridgestone’s “3G” identification isn’t molded on the tire’s sidewall or printed on its label, it is confirmed by the cooling fin technology molded into the sidewalls as shown in the accompanying photos.
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.
