The Ecopia H/L 422 Plus RFT is an ecologically oriented Crossover/SUV Touring All-Season self-supporting run-flat tire designed to provide temporary extended mobility in case a puncture allows complete air loss. Featuring Bridgestone’s third generation run-flat technology (3G RFT), the Ecopia H/L 422 Plus RFT was developed for Original Equipment (O.E.) use on the 2014 Nissan Rogue. Ecopia H/L 422 Plus RFT tires are designed to enhance vehicle fuel economy by reducing tire rolling resistance* along with the vehicle’s carbon dioxide (CO2) emissions while delivering all-season traction, even in light snow.
The Ecopia H/L 422 Plus RFT uses an all-season tread compound featuring Bridgestone’s unique NanoPro-Tech (Nanostructure-Oriented Properties Control Technology) to reduce rolling resistance and energy loss while maintaining dry, wet and wintertime traction.
This compound is molded into a symmetric tread design that combines notched shoulders and intermediate ribs with independent center blocks for dry road tracking and traction. Four circumferential grooves are designed to help water flow from under the footprint to resist hydroplaning and enhance wet traction, while notches and sipes increase the edges that bite into light snow.
The tire’s internal structure includes twin steel belts reinforced by spirally wrapped nylon on top of a polyester casing to blend ride comfort and durability. The structure of the Ecopia H/L 422 Plus RFT features Bridgestone Side Support Run-Flat technology reinforced sidewalls to support the vehicle after a puncture causes a loss of air pressure.
