In recent years, the governments of the world have enacted laws and regulations on the rolling resistance of tires.

Certification introduction
The U.S. Environmental Protection Agency's SmartWay certification is an international authority to test the third party certification, certification more efficient and energy-efficient cars and tires and other auto parts. To reduce fuel consumption, improve air quality and reduce greenhouse gas emissions by encouraging consumers to buy through the certified products.
