It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] like Figure 1 As shown, in this embodiment, the pneumatic sports tire includes a tire body and a tread pattern. The tread pattern includes two tread ribs 1 located in the central area of the tire body, and inner tread blocks 2 and outer tread blocks 3 located in the shoulder areas on both sides of the tire body. A first main tread groove 4 and a second main tread groove 5 are respectively formed between the inner tread blocks 2 and the outer tread blocks 3 and their corresponding adjacent tread ribs 1. A middle main tread groove 6 is formed between the two tread ribs 1. The width and depth of the first main tread groove 4 and the middle main tread groove 6 are both greater than those of the second main tread groove 5. Wear detection holes 7 are formed on both the inner tread blocks 2 and the outer tread blocks 3. The wear detection holes 7 are used to detect the tread depth in the shoulder areas on both sides of the tire body.
[0031] The tire tread pattern features two continuous circumferential tread ribs 1 in the central area of the tire body, separated by a wide and deep circumferential central main tread groove 6. The continuous, uninterrupted tread ribs 1 enhance the rigidity of the tire tread upon contact with the ground, reducing deformation in the longitudinal direction and thus providing excellent handling performance. On both sides of the tire body, on the shoulder areas, there are continuous circumferential inner tread blocks 2 and outer tread blocks 3. The inner tread blocks 2 are separated from the tread ribs 1 by a wide and deep first main tread groove 4, while the outer tread blocks 3 are separated from the other tread rib 1 by a narrow and shallow second main tread groove 5. The second main tread groove 5, in conjunction with the outer tread ribs 1, maintains good and even contact between the tire tread and the ground, enhancing the tire's steering response and grip, and providing excellent handling. Preferably, the tire shoulder tread block area utilizes 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 and enhancing the tire's handling stability. Wear detection holes 7 located on the inner tread block 2 and the outer tread block 3 can conveniently and accurately detect the tread depth at the tire shoulder, facilitating continuous monitoring of tire shoulder wear. Two wide and deep main tread grooves ensure excellent water drainage performance, which, combined with a well-designed tread rib 1, achieves good braking performance. A narrow and shallow main tread groove design, in conjunction with the outer tread block 3 design, maintains good and uniform contact between the tire tread and the ground, enhancing steering responsiveness and grip, while also providing good overall rigidity while ensuring water drainage.
[0032] Furthermore, continue to refer to Figure 1 The outer tread block 3 of the tire has multiple longitudinal fine grooves 8, which are spaced apart along the rotation direction of the tire body. These longitudinal fine grooves 8 improve water drainage, allowing the tire to maintain good handling performance on wet roads, and also increase longitudinal grip, improving cornering performance. Multiple wear detection holes 7 are located between adjacent longitudinal fine grooves 8, allowing for convenient and accurate detection of tread depth at the tire shoulder, facilitating continuous monitoring of tire shoulder wear.
[0033] Furthermore, continue to refer to Figure 1 The inner tread block 2 of the tire has multiple lateral braking grooves 9. These grooves are spaced apart along the rotation direction of the tire body, improving water drainage and achieving excellent wet braking performance. The design employs three different pitch widths and multiple pitch numbers, with the pitch width between two adjacent lateral braking grooves 9 ranging from 50 to 100 mm and the number of pitches from 20 to 35. This design helps reduce tire noise and improve ride comfort.
[0034] Furthermore, continue to refer to Figure 1 Along the normal direction of the outer circumference of the tire body, the sidewalls of the first main tread groove 4 and the middle main tread groove 6 are inclined. The main tread grooves have an inclined groove wall design, which has the ability to quickly drain water and has the self-cleaning ability to prevent stones from getting stuck. It can effectively ensure the driving experience on wet and slippery roads, ensure wet grip, and improve driver safety.
[0035] Furthermore, continue to refer to Figure 1 The width of the outer tread block 3 is greater than that of the inner tread block 2, and the tread pattern is asymmetrical. The wide and deep main tread grooves, combined with the reasonable tread rib design 1, ensure good water drainage performance, thereby achieving good braking effect. The narrow and shallow main tread grooves, combined with the wider outer tread block 3, can maintain good and uniform contact between the tire tread and the ground, enhancing the responsiveness and high grip during steering.
[0036] Furthermore, continue to refer to Figure 1 One of the two tread ribs 1 has a first oblique groove 10, and the other tread rib 1 has a second oblique groove 11. The first oblique groove 10 includes two groove portions, which are spaced apart and are respectively connected to the first main tread groove 4 and the middle main tread groove 6. The second oblique groove 11 is connected to the middle main tread groove 6, which can further improve the rigidity of the tread when it touches the ground, reduce the front-rear deformation of the tread, and provide good handling performance.
[0037] This embodiment also provides a vehicle, including a wheel hub and the aforementioned pneumatic sports tire, which is mounted on the wheel hub. Specifically, the pneumatic sports tire has wear detection holes 7, which are used to detect the tread depth in the shoulder areas on both sides of the tire body, facilitating observation of the wear condition of the tire shoulders at any time. The design of two wide and deep main tread grooves plus one narrow and shallow main tread groove maintains good and uniform contact between the tire tread and the ground, enhancing the tire's steering response and grip, and greatly improving the vehicle's handling.
[0038] 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.
