Description

Technical Field

[0001] The invention relates to the technical field of tires, in particular to a comfortable and durable tire tread pattern structure. Background Art

[0002] Tires are the only parts of vehicles (such as motorcycles, electric vehicles, etc.) that are in direct contact with the road surface. Their main functions are to bear the load, transmit the power required for the vehicle to drive, enable the vehicle to drive stably, cope with different road conditions, etc. The tire pattern has an important impact on the vehicle's power / braking performance, drainage performance, grip performance, driving comfort, and driving safety.

[0003] When a vehicle is driving at high speed, its tires need to have grip, drainage, stability and traction on different road surfaces. However, the current tire pattern design has relatively simple functions, and small stones are easily stuck in the tread grooves. At this time, sharp stones may puncture the rubber outer layer of the tire, causing air leakage and affecting driving safety. Secondly, when the stones rub directly against the ground, abnormal noise will be generated, thus affecting the comfort of the tire during driving. Summary of the invention
