[0009] A plurality of second middle transverse grooves are arranged through the middle tread group and along the tire movement direction, and each second middle transverse groove penetrates through two of the middle inclined grooves and is located between adjacent first middle transverse grooves;

[0010] The middle tread group is divided by the middle inclined grooves, the first middle transverse grooves, and the second middle transverse grooves to form first middle tread blocks, second middle tread blocks, and third middle tread blocks with three different shapes and sizes from the inside out.

[0011] In some embodiments, the middle part of each of the middle inclined grooves has an inclined straight-line segment structure, and both sides thereof have a three-fold segment structure.

[0012] In some embodiments, the entire middle first transverse groove has a straight-line structure; the middle second transverse groove is composed of three straight-line segment structures from one end to the other end, and the height of each straight-line segment structure changes step by step.

[0013] In some embodiments, it further includes:

[0014] A plurality of shoulder transverse grooves, which are arranged through the side pattern group and along the tire movement direction. Each of the shoulder transverse grooves includes a side narrow groove and a side wide groove.

[0030] Compared with the prior art, the beneficial effects of the present utility model are as follows: During the driving of the vehicle, the middle part of the tread is the most important core part, which not only contacts the ground to ensure the controllability of the vehicle, but also is the part where deformation and noise are generated most frequently when contacting the ground. By the staggered separation method between the middle inclined groove, the middle first transverse groove and the middle second transverse groove, the middle tread blocks are separated into three tread block structures with inconsistent shapes, sizes and structures to form an interlocking structure. Through the above method, the hysteresis of deformation during the force extrusion process of the tread blocks is reduced, and the force is more uniform, thereby making the control more stable, the noise generated by the impact with the ground lower, and the noises formed by the tread blocks with different structural shapes will not be inconsistent, thus avoiding the harshness caused by the superposition of the same-frequency and continuous noises.

[0036] Referring to "embodiment" in the present utility model means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the present utility model. The appearance of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those of ordinary skill in the art explicitly and implicitly understand that the embodiments described by the present utility model can be combined with other embodiments without conflict.

[0037] A tire tread pattern includes a central tread pattern group located in the middle of the tread surface and side tread pattern groups located on both sides of the tread surface. The central tread pattern group includes:

[0038] A plurality of central oblique grooves 1 are provided inside the central tread pattern group and arranged along the tire movement direction, and each central oblique groove 1 has a multi-folded segment structure; the setting structure form of the central oblique groove 1 is specifically set inside the central tread pattern group, that is, it is not connected to the side longitudinal grooves 13 on both sides thereof. Specifically, the middle of the central oblique groove 1 has an inclined straight segment structure, and its two sides have a three-folded segment structure. Similarly, other structural form designs can also be adopted, such as the middle of the central oblique groove 1 also having a three-folded segment, or its two sides having a straight segment structure. The central oblique groove 1 is arranged inside the central tread pattern group and set to have a multi-folded segment structure to ensure its overall strength while cutting the tread blocks and increase the friction force by increasing the included angles at multiple angles.

[0039] A plurality of first middle transverse grooves 2 are disposed through the middle pattern group and arranged along the tire movement direction, and each first middle transverse groove 2 penetrates through three middle inclined grooves 1; specifically, the first middle transverse groove 2 is in an overall linear structure.

[0040] A plurality of second middle transverse grooves 3 are disposed through the middle pattern group and arranged along the tire movement direction, and each second middle transverse groove 3 penetrates through two middle inclined grooves 1 and is located between adjacent first middle transverse grooves 2; specifically, the second middle transverse groove 3 is composed of three straight-line segment structures from one end to the other end, and the height of each straight-line segment structure changes step by step. As shown in the figure, the height gradually increases from left to right.

[0041] The specific functions of the first middle transverse groove 2 and the second middle transverse groove 3 are to form the cutting and separation of the tread blocks and form a conductive channel to meet the functions of draining water, sand, mud, and exhaust. Specifically, the first middle transverse groove 2 is respectively located at the middle and both ends of the middle inclined groove 1, and the second middle transverse groove 3 is located at the positions close to the middle and the inflection points on both sides of the middle inclined groove 1. Thus, the middle pattern group forms the first middle tread block 4, the second middle tread block 5, and the third middle tread block 6 with three different shapes and sizes from the inside out through the separation of the middle inclined groove 1, the first middle transverse groove 2, and the second middle transverse groove 3.

[0042] Through the above distribution method, the upper and lower adjacent first middle tread blocks 4, second middle tread blocks 5, and third middle tread blocks 6 are alternately arranged in the middle of the tread in a centrosymmetric manner. The structural shapes and sizes of each tread block are all different, and the side lengths are also different. Thus, through the above arrangement, the bite between them is enhanced. When the tire grip tread blocks are deformed under force, through the mutual biting and extrusion process of different tread blocks, the deformation hysteresis of the tread blocks is reduced, the traction of the tire is improved, and at the same time, the force distribution is more uniform, the driving process is more stable, and thus the impact noise of the tire on the road surface is effectively reduced.

[0043] In some embodiments, it further includes:

[0044] A plurality of shoulder transverse grooves are disposed through the side pattern group and arranged along the tire movement direction. Each shoulder transverse groove includes a side narrow groove 15 and a side wide groove 16. The side narrow groove 15 is close to the inner side of the tread, and the width of the side narrow groove 15 is smaller than the width of the side wide groove 16.

[0045] The transverse shoulder grooves combine narrow and thick tread grooves to enhance the overall continuity of the shoulder tread blocks. When the tire is running, the force linkage of the shoulder tread blocks is better, which can improve the dry grip. At the same time, when the airflow in the side longitudinal groove 13 is transmitted to the side narrow groove 15, the flow velocity of the airflow can be reduced, so that the airflow will not quickly pass through the shoulder tread grooves and be discharged, reducing the occurrence probability of sharp noise. And in order to ensure the guiding effect of the airflow, a flare 17 with a reduced diameter structure from the inner side of the tread to the outer side of the tread is provided at the inner end of the side narrow groove 15; the width of the smallest end of the flare 17 is greater than the width of the side narrow groove 15.

[0046] In some embodiments, the total width of the two side longitudinal grooves 13 provided between the middle tread pattern group and the side tread pattern group accounts for 5%-8% of the width of the tread running surface; the width of the middle inclined groove 1 is 50%-60% of the width of the side longitudinal groove 13.

[0047] In some embodiments, it further includes:

[0048] The first steel sheet 7, the third steel sheet 9, and the seventh steel sheet 18 respectively penetrate through the middle first tread block 4, the middle third tread block 6 and the side tread pattern group, and are integrally in a continuous multi-folded structure;

[0049] The fourth steel sheet 10 and the eighth steel sheet 19 respectively penetrate through the middle third tread block 6 and the side tread pattern group semi - throughly, and are integrally in a continuous multi-folded structure.

[0050] The second steel sheet 8 penetrates through the middle first tread block 4 semi - throughly;

[0051] The fifth steel sheet 11 penetrates through the middle second tread block 5;

[0052] The tenth steel sheet 21 penetrates through the side tread pattern group semi - throughly;

[0053] The second steel sheet 8, the fifth steel sheet 11, and the tenth steel sheet 21 are integrally in a continuous multi-folded structure;

[0054] The sixth steel sheet 12 penetrates through the middle second tread block 5 semi - throughly;

[0055] The ninth steel sheet 20 penetrates through the side tread pattern group;

[0056] The sixth steel sheet 12 and the ninth steel sheet 20 are integrally in a continuous multi-folded structure.

[0057] Specifically, the inner end of the sixth steel sheet 12 is connected to the outer end of the middle inclined groove 1.

[0058] The corresponding steel sheet structure is set up in conjunction with the overall tread block structure. Through the semi-penetration and full-penetration matching methods, the rigidity strength of the corresponding tread blocks is adjusted, and good vehicle handling is provided, thereby giving the driver and passengers a better driving experience. The overall steel sheet mostly adopts a continuous structural design and is matched with a multi-fold line structure to improve its grip performance.
