A plurality of second grooves 121 extending obliquely are arranged at intervals on both sides of the second tire portion 12. Along the radial direction of the tire body 1, the second grooves 121 on both sides of the second tire portion 12 have the same inclination direction, so that the second tire portion 12 has good drainage performance, enhances the lateral and circumferential forces of the second tire portion 12, improves the strength of the second tire portion 12, and is beneficial to the steering maneuverability of the tire when driving on unpaved roads.

[0031] Specifically, in the drawings, direction a refers to the axial direction of the carcass 1 , and direction b refers to the radial direction of the carcass 1 .

[0032] Specifically, line AB in the drawings indicates the crown centerline of the tire.

[0033] In this embodiment, along the radial direction of the tire body 1, the plurality of first grooves 111 on the first side of the first tire portion 11 and the plurality of first grooves 111 on the second side of the first tire portion 11 are arranged alternately. Specifically, the plurality of first grooves 111 on the first side of the first tire portion 11 and the plurality of first grooves 111 on the second side of the first tire portion 11 are arranged in parallel. Such an arrangement further effectively ensures the grip performance and handling stability of the middle part of the tire, i.e., the position of the first tire portion 11.

[0034] In this embodiment, the first tire portion 11 is further provided with a third groove 112, which is located between the first tread grooves 111 on both sides of the first tire portion 11. Specifically, there is one third groove 112, and the tread crown centerline is used as the axis of symmetry. The provision of the third groove 112 further enhances the drainage and sediment removal capability of the first tire portion 11, ensuring that the middle of the tire is reliable and stable.

[0035] In some other optional implementations, the number of the third grooves 112 may also be multiple.

[0036] In this embodiment, along the radial direction of the tire body 1, the plurality of second tread grooves 121 on the first side of the second tire portion 12 and the plurality of second tread grooves 121 on the second side of the second tire portion 12 are arranged one by one opposite to each other and form a plurality of V-shaped structures. Such an arrangement can further enhance the lateral and circumferential forces of the second tire portion 12, improve the overall strength of the second tire portion 12, and facilitate the steering controllability of the tire during driving on unpaved roads.

[0037] In this embodiment, along the radial direction of the tire body 1, the inclination directions of the plurality of second grooves 121 of the two second tire portions 12 are opposite, that is, the openings of the V-shaped structures formed by the two second grooves 121 arranged opposite to each other in the two second tire portions 12 are opposite to each other.

[0038] In this embodiment, the tire structure further includes two third tire portions 13, with the crown centerline as the central axis, the third tire portion 13 is located outside the two second tire portions 12, and a second groove 102 is formed between the third tire portion 13 and the adjacent second tire portion 12. A plurality of third tread grooves 131 extending obliquely are arranged at intervals on both sides of the third tire portion 13, and along the radial direction of the carcass 1, the plurality of third tread grooves 131 on the first side of the third tire portion 13 and the plurality of third tread grooves 131 on the second side of the third tire portion 13 have the same inclination direction.

[0039] In this embodiment, the third tire portion 13 corresponds to the shoulder of the tire. The third tread groove 131 on the inner side of the third tire portion 13 is beneficial to the turning controllability of the tire on a paved road, and the third tread groove 131 on the outer side of the third tire portion 13 improves the water film cutting ability of the tire shoulder on a wet road on the basis of ensuring the steering controllability of the shoulder pattern, and improves the water absorption and drainage performance of the pattern.

[0045] In this embodiment, the width of the first transition groove 1111 , the second transition groove 1211 , and the third transition groove 1311 ranges from 0.5 mm to 10 mm.

[0046] In this embodiment, the pitch widths between two adjacent first tread grooves 111 , between two adjacent second tread grooves 121 , and between two adjacent third tread grooves 131 are 25 mm-60 mm.

[0047] Specifically, the first tread groove 111, the second tread groove 121 and the third tread groove 131 are composed of 3-5 pitches of different widths, with a pitch width of 25mm-60mm and a pitch number of 45-85, which improves the tire's grip on all road conditions while reducing the driving noise and rolling resistance of the tire pattern.
