In recent years, the governments of the world have enacted laws and regulations on the rolling resistance of tires. America in December 2007, according to the energy and security proposals approved by the Congress and the president, proposed traffic department to establish a national motor vehicle replacement tires fuel economy rating system, to help consumers decide to buy tires of intention.
