The Ecopia EP422 featuring H- or V-speed rated sizes is one of Bridgestone's ecologically oriented Grand Touring All-Season tires developed for the drivers of coupes, sedans, minivans and small crossover vehicles looking to combine year-round traction, handling and comfort with reduced environmental impact. Ecopia EP422 tires are designed to enhance vehicle fuel economy by reducing tire rolling resistance along with the vehicle's carbon dioxide (CO2) emissions while delivering year-round, all-season traction, even in light snow.
The Ecopia EP422 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 sidewalls feature Bridgestone's Fuel Saver compound to further increase efficiency.
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.
