[0002] In order to allow consumers to consume clearly, the European Union passed the "General Motor Vehicle Safety Regulations" (661 / 2009) in July 2009. The regulations put forward minimum requirements for passenger car, light truck and truck tires. Only through the use of tire labels Only when consumers fully understand the characteristics of tires can they maximize tire safety, reduce CO2 emissions, and reduce noise. In November 2009, the European Union passed the "Tire Labeling Regulations" (1222 / 2009), which stipulates that tire manufacturers must Provide consumers with some information on the performance of tires, and within the specified period must meet the minimum requirements of Regulation (EC) 661 / 2009 on rolling resistance, noise and wet grip of tires. These three performances correspond to tires respectively. Fuel-saving efficiency, comfort performance and safe handling performance, and the three performances of tires are mutually influencing, improving the fuel-saving efficiency of tires will reduce the safety performance of tires, and improving the safety performance of tires will affect the comfort of tires sex
