On May 17, 2026, information from the State Intellectual Property Office showed that a patent called “A Stability Maintenance Tire” applied by Shandong Linglong Tire Co., Ltd. was authorized. The authorization announcement number is CN224240752U, and the authorization announcement date is May 15, 2026.
This patent application number is CN202520970858.4, the application publication date is May 15, 2026, and the application date is May 16, 2025.
Judging from the patent abstract, the stability-maintaining tire disclosed in this utility model relates to the field of vehicle tire technology.
The top of the tire consists of a center block, shoulder blocks and staggered inclined grooves.
The central main groove is distributed along the circumferential direction of the tire and extends in the tire width direction; the transverse groove is located in the pattern block area extending along one side of the tire width direction of the central pattern block divided by the central main groove; the stability maintenance structure is arranged in the area between the pattern block and the central pattern block.
This tire improves wetland safety through a collaborative diversion mechanism: the central main groove guides water laterally to the arrow-feather-shaped stabilization structure, and uses its side wall angle and rounded transition design to disperse the concentrated water flow into multiple streams; the transverse grooves further accelerate the discharge of water through directional guidance, forming graded diversion and dynamic pressure balance, effectively reducing the residual water film on the tread, enhancing the direct contact between the tire and the road surface, thereby improving the grip and drainage efficiency of wet roads.
