AI Technical Summary
It is difficult for existing pneumatic tires to fully utilize the edge component function of the annular groove on snowy roads and poor roads, resulting in insufficient tire performance.
A pneumatic tire is designed, which has an annular groove arranged away from the main groove in the tire width direction. The annular groove has a polygonal shape. The shortest length of multiple partial grooves is more than 40% of the longest length, and the grooves are connected by width. The structure of the peripheral connecting groove connects the annular groove with the main groove, ensuring that the edge components of the annular groove are fully grounded.
Through this structure, the tire can more effectively utilize the edge components of the annular groove on bad roads and snowy roads, improve the tire's steering stability and drainage performance, and reduce the generation of air column tube resonance sound.
