Goodyear Assurance Fuel Max Tires

Promising a significant 4 percent gain in fuel economy, the Fuel Max tire will be standard equipment on the Chevrolet Volt when it goes into production late next year. A new tread compound reduces rolling resistance, meaning less energy lost to friction, with no reduction in dry- or wet-weather traction. In August, an Australian couple set a new world mileage record on the Fuel Max Tires, managing 67.9 mpg over a 9,000-mile, three-week trip through the U.S. in a stock Volkswagen Jetta TDI diesel, whipping the 58.82-mpg record they had set the previous year in the same car over the same route.
