The Turanza ER33 RFT is Bridgestone’s Grand Touring Summer run-flat tire developed for Lexus GS430 and GS450H sedans, as well as GS460 and GS460 L models. The Turanza ER33 RFT is designed to combine temporary extended mobility (for a distance of 50 miles at up to 50 mph even after a puncture has allowed complete air pressure loss) with good looks, predictable handling and low noise, as well as dry and wet road traction. Like all summer tires, the Turanza ER33 RFT is not intended to be driven in near-freezing temperatures, through snow or ice.
The Turanza ER33 RFT molds a summer tread compound into a 5-rib, symmetric tread design that provides predictable handling and traction on dry roads, while circumferential tread grooves and lateral notches help evacuate water from under the tire’s footprint to enhance wet traction and reduce hydroplaning.
The tire’s internal structure features twin steel belts reinforced by spirally wrapped nylon stabilizing the tread area to enhance handling and high-speed capability. The Turanza ER33 RFT features a rayon or polyester cord body (depending upon application) to enhance ride. The structure of the Turanza EL400 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.
