Our tire national standard still stays in 1997

The annual 3-15 party, summed up in one sentence is: "Do not know, look surprised." Suddenly one day, you will find yourself living on such a planet. Our happy life started from the bottle containing bisphenol A. After experiencing various tests such as waste oil and Sudan Red, Kumho Tire gave us a chance to experience it. What puzzles me is that how these things took a long time and have always occurred depends on a 3/15 party to be valued.

As early as in 2009, Kumho Tires, which had been criticized by the General Administration of Quality Supervision, Inspection and Quarantine, had been complaining about high levels of complaints and far ahead of other brands. In more than 500 complaints about tires in a car professional website, Kumho tires accounted for more than 70%. Users generally report that Kumho tires are cracking, bulging or even appearing on the road within a few hundred kilometers, a few thousand kilometers, or a car purchase in less than a year. A puncture. The official response from Kumho was: “The 24.8 million tires did not have a bulge. Only God could do it. The bulging of tires was mostly caused by improper use, and it was not related to quality.” After the explanation, it seems that everything has been sealed in storage. We have not seen the AQSIQ investigation of Kumho.

In doing this issue, I inadvertently inquired about China's current tire quality standards and found that the current implementation of the tire quality standards is still released in 1997, and there have been no changes in the past years. In the past ten years or so, China’s automotive consumption environment and driving environment have long since turned upside down; tires, the most important accessories in the automotive field, have failed to keep pace with the development speed of automobiles and roads.

It is understood that in the United States and Europe, the test standards for tires have been increased in 2007, the test speed has been increased from 137 kilometers per hour to 160 kilometers, and the durability test mileage has also been increased from 3,000 kilometers to 4,080 kilometers. , also required to test knock-off, aging and breathability. If we compare our quality standards with these countries, we will only be ashamed.
