The Energy Saver A/S Selfseal is Michelin's most fuel-efficient All-Season Passenger car tire developed for the drivers of electric, hybrid and fuel-efficient passenger cars that want to exploit their vehicle's fuel economy without abandoning dry, wet and wintertime traction and also want the additional peace of mind their travels will not be delayed by typical tread area punctures. Designed to deliver self-sealing continuing mobility, Energy Saver A/S Selfseal tires feature a sticky, viscous coating on the inside of the tire that instantly seals nail or screw punctures up to ¼" in diameter. The Selfseal Technology is designed to permanently fill the path of the puncture when the object is removed.Representing the forefront of Michelin's Green X technology, Energy Saver A/S Selfseal tires can enhance vehicle operating efficiency and environmental impact by reducing fuel consumption and carbon dioxide emissions while delivering year-round traction, even in light snow.Expanding on the technologies of the Michelin Energy Saver summer tires introduced in Europe during 2007, the Energy Saver A/S Selfseal offers exceptionally low rolling resistance at or below the levels offered by its European summer tire counterpart.The Energy Saver A/S Selfseal features Michelin's EnergySaver Construction combined with a unique silica-based tread rubber that helps improve engine fuel efficiency by keeping the tire cooler. This compound is molded into a symmetric design that features siped, independent tread blocks to combine predictable handling, no compromise stopping performance and all-season traction without trading fuel efficiency. Circumferential and lateral grooves direct water through the tread design to help resist hydroplaning and enhance wet traction.Michelin Comfort Control Technology uses computer-optimized design and precision manufacturing to reduce vibrations and road noise to keep the vehicle quiet. The tire's internal structure includes twin steel belts reinforced by spirally wrapped polyamide on top of a polyester cord casing to combine strength, efficiency and comfort.
