Michelin Says Tire Can Improve Mileage by 8 Percent Without Hurting PerformanceBy Scott Doggett June 9, 2009
If you've ever attended a fuel-efficiency competition such as Shell's annual Eco-marathon America, you likely know the importance hypermilers give to rock-hard tires to minimize roll resistance and maximize fuel economy.
The drawback to riding on tires with as much give as, say, a 50-pound steel workout weight is that they feel like you're riding on solid-steel tires.
Michelin announced today that it's come up with a new tire line that is up to 8 percent more fuel efficient than other tires in its class, can reduce a vehicle's carbon-dioxide emissions and do both things without compromising performance.
And - surprise! - Michelin timed the announcement to correspond with the line's availability in stores nationwide.
The tire manufacturer says the technology engineered into its Michelin Energy Saver all-season tire is the result of more than 16 years of research and development in the area of rolling resistance and fuel-efficiency.
With the tire, Michelin engineers were able to achieve and deliver increased fuel efficiency by decreasing the levels of rolling resistance, or energy loss in the tire, the company said in a statement.
To prevent the tire from providing a ride that's as stiff as surfboard, Michelin used "computer-optimized design and precision manufacturing to offer greatly reduced vibrations and road noise to keep the vehicle quiet, while a silica-based rubber compound provides all-season traction."
The tire is available in four sizes that include popular mainstream and hybrid vehicles. The sizes are: P215/60R16; P195/65R15; P195/60R15 and P185/65R15.
