[0034] like Figure 1 As shown, in this embodiment, the sports tire includes a tire body and a tread pattern. The tread pattern includes three parallel and spaced main grooves 1. A tread rib 2 is provided between each pair of adjacent main grooves 1. The two tread ribs 2 are located in the central area of the tire body. The tread ribs 2 have oblique grooves 3, each including a first groove portion 31 and a second groove portion 32. A chamfer 33 is provided on one side of the groove wall of the first groove portion 31 and on the other side of the groove wall of the second groove portion 32. The opening directions of the corresponding chamfers 33 between the first groove portion 31 and the second groove portion 32 are opposite to each other.
[0035] The tire tread pattern features two continuous, uninterrupted circumferential tread ribs 2 in the central area of the tire body. A main tread groove 1 is positioned between the two ribs 2. Along the width of the tire body, three main tread grooves 1 and two ribs 2 are alternately arranged, meaning there is a rib 2 between every two adjacent main tread grooves 1. Small transverse oblique grooves 3 are formed on the ribs 2. Optionally, multiple oblique grooves 3 are provided, spaced apart along the rotation direction of the tire body. A chamfer 33 is provided on one side of the groove wall of the first groove portion 31, and a chamfer 33 is provided on the other side of the groove wall of the second groove portion 32. The opening directions of the chamfer 33 of the first groove portion 31 and the second groove portion 32 are opposite to each other, which improves the overall rigidity of the tire, reduces the longitudinal deformation of the tread pattern, and provides good handling. Preferably, the three main tread grooves 1 have an angled groove wall design, which provides rapid drainage and self-cleaning ability to prevent stone trapping, effectively ensuring a smooth driving experience on wet and slippery roads and guaranteeing wet grip. The narrow, circumferential main tread grooves 1 between the two tread ribs 2, combined with the overall wide tread rib design, maintain good and even contact between the tire tread and the ground, as well as the overall rigidity of the tire tread, enhancing steering response and grip, and providing excellent handling.
[0036] Preferably, the first groove portion 31 and the second groove portion 32 are spaced apart, and the central axis of the first groove portion 31 and the central axis of the second groove portion 32 coincide. The first groove portion 31 and the second groove portion 32 located on the inner and outer sides of the tire shoulder at the same position are on the same oblique line, and the first groove portion 31 and the second groove portion 32 are not connected, which further enhances the handling performance.
[0037] Furthermore, continue to refer to Figure 1 The tread pattern has a centrally symmetrical structure and includes inner tread blocks 4 and outer tread blocks 5. The inner tread blocks 4 and outer tread blocks 5 are located on the inner and outer sides of the tire shoulder area, respectively. A main tread groove 1 is formed between the inner tread block 4 and a tread rib 2, and a main tread groove 1 is formed between the outer tread block 5 and another tread rib 2. Both the inner tread blocks 4 and outer tread blocks 5 have lateral grooves 6. The lateral grooves 6 are narrow and shallow. Preferably, there are multiple lateral grooves 6, spaced apart along the rotation direction of the tire body.
[0038] The lateral groove 6 includes a first tread groove portion 61 near the center area of the tire body and a second tread groove portion 62 near the shoulder area of the tire body. The first tread groove portion 61 is spaced apart from the main tread groove 1, and the second tread groove portion 62 is spaced apart from the sidewall edge of the tire body. The lateral groove 6 does not penetrate the entire inner tread block 4 and the outer tread block 5, maintaining the rigidity of the shoulder tread block, enhancing the responsiveness and high grip during steering, while also balancing wear resistance and comfort. This allows the tire tread to maintain excellent wet grip even in the later stages of wear, making driving performance on slippery roads even more outstanding.
[0039] The opening of the first tread groove 61 is larger than that of the second tread groove 62, which is beneficial to the tire's water drainage and allows the tire to maintain good handling performance on wet and slippery roads, while not sacrificing the rigidity of the entire tread block, thus maintaining the rigidity of the inner tread block 4 and the outer tread block 5 of the shoulder. The lateral grooves 6 adopt a design with three different pitch widths and multiple pitches. The pitch width between two adjacent lateral grooves 6 ranges from 50 to 100 mm, and the number of pitches ranges from 20 to 35, which helps to reduce tire noise and improve ride comfort.
[0040] Furthermore, continue to refer to Figure 1 The width and depth of the main tread groove 1 between the two tread ribs 2 are smaller than those of the other two main tread grooves 1. The two wide and deep main tread grooves 1 ensure good drainage performance, and combined with the well-designed tread ribs 2, achieve good braking effect. The design of a narrow and shallow main tread groove 1, along with the design of the outer tread block 5 and the inner tread block 4, maintains good and uniform contact between the tire tread and the ground, enhancing steering responsiveness and high grip. Simultaneously, it provides good overall rigidity while ensuring drainage. Preferably, the shoulder tread block area uses a special tread curvature design to optimize the shape of the contact patch and the distribution of contact stress at the tire shoulder, preventing premature wear at the shoulder and enhancing the tire's handling stability.
[0041] This embodiment also provides a vehicle, including a wheel hub and the aforementioned sports tire, which is mounted on the wheel hub. Specifically, the tread pattern has two tread ribs 2 in the central area of the tire body. The tread ribs 2 have oblique grooves 3. The first groove 31 has a chamfer 33 on one side of its groove wall and the second groove 32 has a chamfer 33 on the other side of its groove wall. The opening directions of the corresponding chamfers 33 between the first groove 31 and the second groove 32 are opposite to each other, which can improve the overall rigidity of the tire, reduce the front-rear deformation of the tread pattern, and provide good handling for the vehicle.
[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
