The Energy Saver is Michelin's fuel-efficient Grand Touring Summer tire developed for drivers that want to maintain/enhance their vehicle's fuel economy without forsaking dry and wet traction. Originally introduced as Original Equipment (O.E.) on European passenger cars, Energy Saver tires are designed to complement vehicle operating efficiency and environmental impact by reducing fuel consumption and carbon dioxide emissions. Like all summer tires, Energy Saver tires are not intended to be driven in near-freezing temperatures, through snow or on ice.Energy Saver tires feature a low rolling resistance compound molded into an asymmetric tread design with smooth-rolling tread ribs to combine predictable handling, reliable stopping performance and respect for the environment. Circumferential grooves and lateral notches direct water through the tread design to help resist hydroplaning and enhance wet traction.Computer-optimized design and precision manufacturing methods have earned Energy Saver tires Michelin's Green X status, identifying they are among the most fuel-efficient tires available today. The tire's internal structure includes twin steel belts reinforced by spirally wrapped fabric on top of a polyester cord casing to combine strength, efficiency and comfort.Note: If available in an appropriate size for the vehicle, Michelin Energy Saver A/S All-Season Passenger car tires offer exceptionally low rolling resistance at or below the levels offered by Energy Saver summer tires.*Specific sizes featuring Green X Technology are identified as such on the Sizes tab, as well as on the tire's Specs tab.
