Energy reduction is common automotive manufacturers today face a difficult problem, but energy consumption may account for car tires for 20% of the total energy consumption, so as an important component of auto parts, tire energy is essential. In recent years, the European Union, the United States have legislation on parameters such as tire rolling resistance requirements of proposed limits. The European Union, the United States is a major tire manufacturers in China export market, understanding of national regulations on enterprises to adjust production and distribution of great significance.

    European Union

    EU November 25, 2009 formally adopted the 779 number, "the European Parliament and European Council on the fuel efficiency and other necessary parameters of the tire label instructions," This is the territory of the EU automotive production and sales of the implementation of vehicle type Certification (WVTA) system and the matter content of polycyclic aromatic hydrocarbons contained in the tire limit (REACH), after another new instruction. Directive No. 779 the next 3 years all tires to be imported into the EU in the key parameters of the tire on the label: fuel efficiency levels, wetlands, rolling holding properties as well as external noise. The efficiency of the label into the tire A, B, C, D, E, F, G grades 7, best to worst according to Green "A" until the red "G" flag logo. In order to better promote fuel-efficient tires, the EU countries will reach at least grade C class tire fiscal incentives. The range of vehicles including the EU Common Security Act [Com (2008) 316] the provisions of the C1 (mainly for passenger car tires), C2 (mainly for light vehicle tires), C3 (mainly for heavy vehicles in the tires). 779 Directive requires EU member states no later than on November 1, 2011 and published consistent with the directive by the laws, regulations and administrative provisions, from November 1, 2012 come into force.

    United States

    The new regulations include the United States labeling and EPA's Smartway certification in two parts.

    Labeling system: U.S. National Highway Traffic Safety Administration (NHTSA) on March 30, 2010 documentation requirements and regulations promulgated, all tire manufacturers must be published in the regulations within 12 months, in accordance with the fuel efficiency of replacement tires (rolling resistance ), security (wet road conditions, traction) and durability (tread wear) for classification, and a prominent position in the tire are identified. At present, only the need for fuel-efficient tire replacement grade, first wife tire grading system is not limited. Mainly refers to passenger car tire replacement tire replacement tires. Required to grade the three main indicators of product parameters but also publicity in the car on the U.S. government website. In addition, NHTSA also requires manufacturers to report data in a variety of performance tests, supported by improved grading standards, and recommended that retailers before sale retain all the information on the label tires.

    U.S. Environmental Protection Agency (EPA) of the Smartway Certification: Smartway certification is an international authoritative third-party testing organizations demonstrate, specifically certified energy efficient cars and tires and other auto accessories. By encouraging consumers to purchase goods through this certification, to reduce fuel consumption, improve air quality, reduce greenhouse gas emissions. Currently, access to Smartway certified brand products only from the United States, France, Japan, Germany, Korea and China.

    In addition, as early as the end of 2008, the Japanese economy and trade and Industry Ministry of Land, has announced the development of a regulation on tire fuel efficiency. Japanese tire manufacturer recently introduced a non-mandatory labeling system for tires, rolling resistance of the label will be classified as AAA, AA, A, B and C five levels, the wet grip is divided into a, b, c and d four level.
