In order to respond to EU standards and regulations and the US SmartWay certification, in recent days, the Double Star Qingdao Tire Corp. has sent different patterns of all-steel radial tires to the National Tire Testing Center for rolling resistance test and successfully passed the test. This test verifies the overall safety performance of the Double Star tires, which not only enhances the market's recognition of the company's products, but also lays a good foundation for Double Star tires to develop domestic and foreign markets.
