Recently, the national inspection results of the AQSIQ's car radial tire quality showed that the qualified rate of the company's spot inspections was 53%, and the sample sampling pass rate was 75%. This shows that the quality of domestic radial tires needs to be improved. Car radial tire products have high technical content and are superior to automobile bias tires, which is the development direction of the tire industry. The inspection targets include the 6.50R16 light truck car radial tires and the 70, 80 series car radial tires. Among the 28 samples tested in the 15 companies, 21 samples from 8 companies were qualified. Of the 7 failed samples, 6 samples failed on the outer edge size. Due to the unqualified outer edge size, it will affect the normal driving of the car, and there are hidden hidden dangers in the high-speed state. Industry analysts believe that there are three main reasons for product non-compliance: First, strict control over the raw materials imported into the factory; Second, lax control of the process; Third, production is not in accordance with national mandatory standards, or according to foreign requirements, Domestic market sales.
