Rolling Resistance is a factor in fuel efficiency as it relates to your tires. The phrase means the amount of force needed to keep tires moving at a constant speed. The greater the force needed, the higher your gasoline consumption. Some kinds of fuel efficient tires are engineered to utilize lower rolling resistance and reduce the strain on the engine. In some states, there are studies underway to rate tires for their rolling resistance to assist consumers in finding the most fuel efficient tires they can afford.
