At present, through the continuous efforts of people in the tire industry, a relatively complete tire industry system has been formed in China. The tire production technology has been continuously improved. The tire scientific and technological achievements have been emerging, and many processes have approached or reached the world advanced level. The variety, quality and technical level of Chinese tire products have reached the best level in history, which have greatly reduced the distance with the international advanced level.

Tire production and manufacturing process: with the development of technology, the performance of tires has been greatly improved. Taking Linglong tire as an example, ultra-low section, anti wet slip and low noise passenger radial tire has achieved four breakthroughs in driving comfort, environmental protection, safety and handling; GREENMAXHP010, GREENMAXECOTOURING and other six pattern series have all passed the EU ECE noise certification, won the fuel-saving tire award, and reached the international advanced level; All environmentally friendly tire series have met the requirements of EU REACH regulations; More than 80 product specifications have passed Smartway certification in the United States.

The number of patent disclosures rose as a whole, and the number of applications decreased in the past two years, dragged down by the number of cars. From the change trend of the overall disclosure of patent technologies in China's tire industry, the number of tire patent technologies disclosure every year in China showed an upward trend from 2010 to 2020. Affected by the prosperity of the automobile industry in recent years, the number of patent technologies disclosure has decreased: 13602 in 2019 and 15432 in 2020. By the year of 2020, the total number of patent technology applications in China's main tire industry was 112763 (Baiteng. com). From the change trend of the total number of patent technology applications in China's tire industry, the number of newly applied tire patent technologies in China showed an overall upward trend from 2010 to 2018. Since 2019, the number of patent technology applications has decreased: 13380 in 2019 and 6995 in 2020.
