As competition in the tire industry becomes increasingly fierce, technological innovation has become the key for companies to stand out.
Recently, information from the State Intellectual Property Office shows that Shandong Linglong Tire Co., Ltd. successfully applied for a patent titled “A tire that improves wet grip performance and handling stability”. The authorization announcement number is CN224240751U, and the authorization announcement date is May 15, 2026.
The patent application number is CN202520970855.0, the application publication date is also May 15, 2026, and the application date is May 16, 2025.
Judging from the patent abstract, this utility model tire relates to the field of tire pattern technology, including a central area with transition areas symmetrically provided on both sides of the central area, and a shoulder area on one side of the transition area.
There is a pattern main groove between the center area and the transition area, a pattern side groove between the transition area and the shoulder area, and transverse sipes in the center area, transition area and shoulder area.
By setting a 10° inclination angle at the bottom of the pattern main groove and pattern side grooves and setting up reinforcing bosses in the pattern side grooves, this tire increases the rubber thickness at the bottom of the ribs in the transition zone, thereby improving the longitudinal rigidity of the pattern in the transition zone.
At the same time, the transverse sipe spacing in the central area is made smaller than the transverse sipe spacing in the transition zone. On the premise of ensuring sufficient longitudinal deformation, the rigidity of the pattern ribs in the transition zone is reduced, thereby reducing the risk of shimmy.
This innovative design will effectively improve the tire’s wet grip performance and handling performance, bringing users a safer and more comfortable driving experience.
Linglong Tire was established on June 6, 1994 and listed on the Shanghai Stock Exchange on July 6, 2016. It is a leading enterprise in the domestic tire industry.
The company focuses on the automobile tire business, has advantages in the entire industry chain, and has great investment value.
Its main business is the design, development, manufacturing and sales of automobile tires. The Shenwan industry it belongs to is automobiles – auto parts – tires and wheels, involving concept sectors such as net stocks, flying cars, and tires.
In 2025, Linglong Tire’s operating revenue will reach 24.642 billion yuan, ranking 4th among 22 industry companies, higher than the industry average of 10.395 billion yuan and the median of 5.119 billion yuan.
However, there is still a gap with the first place Zhongce Rubber (44.956 billion yuan) and the second place Sailun Tire (36.792 billion yuan).
Among the main businesses, tire product revenue was 24.475 billion yuan, accounting for 99.32%.
In terms of net profit, it will be 1.369 billion yuan in 2025, ranking third in the industry, higher than the industry average of 701 million yuan and the median of 294 million yuan, but there is a gap with the first-place Zhongce Rubber, 4.147 billion yuan, and the second-place Sailun Tire, 3.617 billion yuan.
It is worth mentioning that Linglong Tire has made fruitful achievements in patent research and development recently.
