[0024] The center of the tire crown 1 is provided with a main tread block 4, and the center line of the main tread block 4 is on the same line as the center line of the tire crown 1.

[0028] The left shoulder 2 is provided with multiple hook-shaped sipes 11, and the right shoulder 3 is provided with transverse grooves 12.

[0029] The main pattern block 4 is continuously provided with groove pattern 13, groove pattern 2 14 and groove pattern 3 15. A groove pattern 2 14 is provided between the two groove patterns 13. Both groove patterns 13 and groove pattern 2 14 are provided on the side adjacent to the longitudinal groove 5. Groove pattern 3 15 is symmetrically provided with groove pattern 2 14.

[0030] The large patterned block 13 is continuously provided with multiple groove patterns 4 16 and multiple groove patterns 5 17, with a groove pattern 5 17 located between two groove patterns 4 16. The groove patterns 4 16 have an inverted V-shaped structure.

[0031] The large patterned block 2 10 is continuously provided with multiple groove patterns 6 18, multiple groove patterns 7 19 and multiple groove patterns 8 20. A groove pattern 7 19 is provided between two groove patterns 6 18. The groove patterns 6 18 and groove patterns 7 19 are provided on the side adjacent to the longitudinal fine groove 8, and the groove pattern 8 20 is provided on the side adjacent to the longitudinal groove 1 5.

[0032] A hook-shaped fine groove 21 is provided between the two hook-shaped knife groove patterns 11.

[0033] The lower end of the transverse groove 12 is provided with a V-shaped fine groove 22, which is located on the side adjacent to the longitudinal fine groove 8.

[0034] The edges of the hook-shaped groove pattern 11, the transverse groove 12, the groove pattern one 13, the groove pattern two 14, the groove pattern three 15, the groove pattern four 16, the groove pattern five 17, the groove pattern six 18, the groove pattern seven 19 and the multiple groove patterns eight 20 are designed with chamfered corners.

[0035] Working Principle: Sipes Disrupt Airflow and Noise Frequency: Multiple sipe patterns (such as sipes one, two, and three on the main tread blocks, and various sipes on the large tread blocks one and two) are distributed in different parts of the tire. When the tire rolls and contacts the ground, these sipes disrupt the direction and pattern of airflow, causing the originally relatively regular airflow and noise frequencies to become turbulent. Noises of different frequencies interfere with each other, and their energy cancels each other out, thereby effectively reducing the intensity of noise and achieving a quiet effect.

[0036] Groove optimization for airflow path: A well-distributed network of longitudinal grooves (longitudinal grooves one, two, three, and fine longitudinal grooves, etc.) and lateral grooves guides airflow along specific paths when the tire contacts the ground, reducing turbulence on the tire surface. Air turbulence is a significant cause of noise; optimizing the airflow path reduces noise generated by turbulence, further improving the tire's quietness.

[0037] Sipe and groove combination for drainage: The main tread pattern features numerous sipes, optimally combined with four circumferential grooves and lateral grooves. When the tire comes into contact with a wet surface, the sipes quickly guide water into the circumferential and lateral grooves. These grooves are interconnected, forming drainage channels that allow water to drain rapidly from the tire surface. Details such as the hook-shaped fine grooves between the hook-shaped sipes and the V-shaped fine grooves at the lower ends of the lateral grooves further increase drainage path and capacity, effectively reducing the thickness of the water film between the tire and the ground and preventing hydroplaning.

[0038] Enhanced rigidity and grip: The hook-shaped sipes and other sipe designs increase the rigidity of the tire surface. This increased rigidity makes the tire less prone to deformation under various road conditions, better maintaining its contact shape and area with the ground. Simultaneously, these tread patterns increase the friction between the tire and the road surface, i.e., grip. During cornering, acceleration, and braking, greater grip provides more stable support and force transmission, allowing the vehicle to move according to the driver's intentions, improving handling performance and driving safety.

[0039] A well-designed layout ensures even stress distribution: the continuous arrangement of the main tread blocks, large tread block one, and large tread block two provides the tire blocks with sufficient rigidity and contact patch area. During driving, this layout ensures more even stress distribution on the tire, preventing uneven wear or performance degradation caused by excessive localized stress. Even stress distribution guarantees the overall strength and durability of the tire, while also helping to maintain stable handling performance, enhancing stability during straight-line driving and improving traction on dry surfaces.

[0040] Chamfered design enhances grip and handling: Chamfered edges are used on the hook-shaped grooves, transverse grooves, and edges of each groove pattern to increase the rigidity of the tread blocks. During braking, the tread blocks are less prone to excessive deformation under stress, maintaining a better shape and effectively increasing the contact area with the road. A larger contact area means greater friction, which increases grip, allowing the vehicle to stop faster during braking. It also improves handling performance during driving, enabling the driver to control the vehicle more precisely.

[0041] In summary, this invention achieves superior water drainage and anti-slip properties through the structural design of hook-shaped sipes and various other sipe patterns. It also disrupts the airflow and noise frequencies generated when the tire rolls and contacts the ground, effectively reducing driving noise and creating a quiet in-car environment for passengers. Furthermore, it increases tire surface rigidity and grip, allowing the tire to maintain better contact with the ground under various road conditions such as turning, acceleration, and braking, providing stable handling performance and improving driving safety and comfort. The hook-shaped fine grooves between the hook-shaped sipes, the V-shaped fine grooves at the lower end of the lateral grooves, and the chamfered edges of each sipe enhance the tire's water drainage performance, reduce hydroplaning on wet roads, and improve tire grip and handling stability. The continuous layout of the main tread blocks, large tread block one, and large tread block two provides sufficient rigidity and contact area, resulting in excellent handling and powerful performance, and significantly enhancing dry traction and straight-line stability. The edges of the hook-shaped sipes, transverse grooves, sipes pattern one, sipes pattern two, sipes pattern three, sipes pattern four, sipes pattern five, sipes pattern six, sipes pattern seven, and multiple sipes pattern eight are chamfered, which improves the rigidity of the tread blocks, reduces the stress deformation during braking, effectively increases the ground contact area, increases grip, and further improves handling performance.
