Recently, public information from the State Intellectual Property Office shows that the invention patent for “a tire performance testing device” filed by Linglong Tire was officially announced. This patent focuses on common difficulties in the field of tire flat spot testing and makes disruptive optimizations to the traditional testing mode. The application of related technologies will greatly improve the efficiency of the tire testing process.
According to the patent abstract, the new test device disclosed this time consists of a frame, a main pressure wheel static pressure system, two sets of eccentric wheel vibration modules, a tire positioning and clamping mechanism, and a control and monitoring system. It abandons the traditional backward test mode that relies on high and low temperature cycles and long-term standstill. It innovatively uses a composite structure with constant static pressure and high-frequency radial vibration. Through vibration
Accelerating the relaxation and creep solidification of rubber molecular chains, greatly compressing the flat-point molding process that originally took dozens of hours to complete, directly increasing the testing efficiency by dozens of times, it can quickly complete the inspection of batch tire samples, perfectly adapting to large-scale and high-efficiency testing needs, and has extremely high application value for tire companies to compress the research and development cycle and improve the efficiency of factory quality control.
As a leading company in the domestic tire industry, Linglong Tire was founded in 1994 and officially launched in 2016. It has focused on the design, R&D, manufacturing and sales of automobile tires for many years. It has advantages in the entire industry chain. Its products cover passenger tires, truck tires, engineering tires, agricultural tires, aviation tires and other categories, and its sales network covers hundreds of countries and regions around the world.
In 2025, the company’s annual operating income will reach 24.642 billion yuan, ranking 4th among the 22 mainstream domestic tire companies, far exceeding the industry average revenue level; the annual net profit will reach 1.369 billion yuan, ranking 3rd in the industry, and its core operating indicators will perform well. Among them, tire product revenue accounts for 99.32% of the total revenue, and the main business focus is extremely high.
The disclosure of this new patent is also the epitome of Linglong Tire’s long-term emphasis on technology research and development.
Combing the recently disclosed patent information of the company, we can see that from the end of 2025 to the first half of 2026 alone, Linglong Tire has disclosed more than 50 patents, covering multiple dimensions such as raw material testing, tire structure design, production process optimization, performance testing verification, and cutting-edge technology exploration.
Relevant technologies for upgrading the performance of existing products also include 3D printing bionic non-pneumatic tires, bio-based material applications, intelligent tire sensor research and development and other cutting-edge technology layouts. The solid technical reserves have also laid a solid foundation for Linglong Tire to further expand the global market and enhance the core competitiveness of its products.
Competition in the global tire market is becoming increasingly fierce. Chinese tire brands are continuously increasing their global market share by virtue of technological upgrades and supply chain advantages. Leading companies represented by Linglong Tire continue to increase investment in research and development, which will also drive the entire Chinese tire industry towards high-end and globalization.
