U.S. DOT Proposes New Tire Fuel Efficiency Ratings for American Consumers
"The U.S. Department of Transportation today proposed a new, consumer-friendly replacement tire label which would include, for the first time, information about the tire’s impact on fuel economy and CO2 emission reductions. Tires with lower rolling resistance – and proper inflation pressure - can contribute to improved fuel economy.

In addition to the new fuel efficiency ratings, the proposal by the National Highway Traffic Safety Administration (NHTSA) also would provide consumers with two other key pieces of tire performance information - wet weather traction and tread wear. All three ratings would be prominently displayed on a removable label attached to the replacement tire at the point of sale.

The new, three-tiered ratings also will appear on safercar.gov to help consumers in compare ratings as they shop for new tires..."
