Description

Technical Field

[0001] This invention relates to the field of tire technology, specifically to a comfortable and durable tire tread pattern structure. Background Technology

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

[0003] When a vehicle tire is traveling at high speed, it needs to have grip, water drainage, stability, and traction on different road surfaces. However, the current tire tread design has a relatively simple function, and small stones can easily get stuck in the tread grooves. At this time, sharp stones may puncture the outer rubber layer of the tire, causing air leakage and affecting driving safety. Secondly, when stones rub directly against the ground, they will produce abnormal noise, which will affect the comfort of the tire while driving. Summary of the Invention

When the tread grooves come into contact with the wheel surface, the groove openings are narrowed due to compression, so stones are less likely to get stuck in the grooves, making the tire more comfortable and durable when driving.
