Low-rolling resistance tires are tires which are designed to improve fuel efficiency of a car by minimizing the energy wasted as heat as the tire rolls down the road. Frictional losses can account for over 80% of the fuel energy consumed by a typical car. Of that, approximately 5–15% is lost to rolling resistance.Low Rolling Resistance Tires (Website).

A 2003 California Energy Commission (CEC) preliminary study estimated that adoption of low-rolling resistance tires could save 1.5–4.5% of all gasoline consumption, but that current data were also insufficient to compare safety and other characteristics.California State Fuel-Efficient Tire Report: Volume I California Energy Commission, July 2003.

A separate study by the Transportation Research Board also found it unclear whether economic and environmental savings would be offset by shorter tire life.”Tires and Passenger Vehicle Fuel Economy: Informing Consumers, Improving Performance — Special Report 286.”, National Academy of Sciences, Transportation Research Board, 2006.

Fuel economy effects are greater for vehicles with hybrid drivetrains and technologies such as cylinder cutout.
Most hybrid vehicles are equipped with low-rolling resistance tires.

Auto manufacturers in the United States typically equip new vehicles with tires that have lower rolling resistance than their average after-market replacements, in order to meet Corporate Average Fuel Economy (CAFE) standards.
