Description

Technical Field

[0001] This invention relates to the field of tire technology, specifically to a tread pattern structure for a performance tire. 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 tread pattern of tires 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 simultaneously provide grip, water drainage, stability, and traction on different road surfaces. However, current tire tread designs have relatively limited functionality, and small stones can easily get stuck in the tread grooves. In this case, sharp stones may puncture the outer rubber layer of the tire, causing air leakage and affecting driving safety. Secondly, the tire's water drainage effect will be weakened, resulting in reduced grip and braking performance on wet and slippery roads, and thus weaker handling performance. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a tread pattern structure for a sports performance tire, which greatly improves the tire's sports performance by setting multiple scientific and aesthetically pleasing tread grooves and redesigning the shape, width, and cross-section of the tread grooves.

[0022] As a preferred embodiment of the tread pattern structure for a performance tire, the tread strip is applied to a motorcycle tire, and the tire's tread ratio is 70% or more and 80% or less.

[0023] As a preferred embodiment of the tread pattern structure of a performance tire, the cross-sectional shape of the tread grooves on the tread module T is a wedge-shaped dovetail with a narrow top and a wide bottom.

[0024] As a preferred embodiment of the tread pattern structure of a performance tire, the tread module T has multiple evenly distributed protrusions connected on both sides of the tread grooves along its opening direction; the surface of the protrusions is an arc surface.

[0025] After adopting the above technical solution, the beneficial effects of the present invention are:

[0026] 1. The tread module T includes three tread grooves arranged on opposite sides relative to the equatorial plane XX of the tire: tread groove one, tread groove two, and tread groove three. Tread groove one is formed by connecting and combining tread groove one a, tread groove one b, and tread groove one c. Tread groove two is formed by connecting and combining tread groove two a, tread groove two b, tread groove two c, and tread groove two d.

[0027] 2. The tread module T also includes tread grooves four arranged on the opposite side relative to the equatorial plane XX of the tire; wherein, tread grooves four are formed by the interconnection and combination of tread grooves foura, fourb and fourc; by adding tread grooves four, the grip and stability of the tire are further improved.

[0028] 3. The tread module T also includes tread grooves five and six arranged on opposite sides relative to the equatorial plane XX of the tire; by adding tread grooves five and six, the tire's grip and stability are further improved, as well as its drainage capacity, reducing the risk of sideslip.

[0029] 4. In order to reduce the number of stones stuck in the tread grooves, the cross-sectional shape of the tread grooves on the tread module T is a wedge-shaped dovetail with a narrow top and a wide bottom. 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.

[0030] 5. To further reduce the risk of stones getting stuck in the tread grooves, protrusions are installed on both sides of the tread grooves. These protrusions effectively block stones, preventing the high-speed rotating tire from losing grip and braking performance due to stones getting stuck, thereby improving the tire's handling performance.
