DETAILED DESCRIPTION

[0024] ​In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described and illustrated in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments provided by the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Obviously, the drawings described below are only some examples or embodiments of the utility model. For ordinary technicians in this field, the utility model can also be applied to other similar scenarios based on these drawings without creative work. In addition, it can be understood that although the efforts made in this development process may be complicated and lengthy, for ordinary technicians in this field related to the content disclosed by the utility model, some changes in design, manufacturing or production based on the technical content disclosed by the utility model are just conventional technical means, and should not be understood as the content disclosed by the utility model is insufficient.

[0026] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments without conflict.

[0027] like Figure 1As shown, the trailer tire pattern includes a tread, and also includes: a left pattern block 1 and a right pattern block 2, the left pattern block 1 and the right pattern block 2 are staggered in a "herringbone" shape on the tread, a through transverse pattern groove 3 is set between the left pattern block 1 and the right pattern block 2 of the previous pitch and the left pattern block 1 and the right pattern block 2 of the next pitch, and a longitudinal pattern groove 4 is set between the left pattern block 1 and the right pattern block 2, and the longitudinal pattern groove 3 is located at the center of the tread. It can be understood that the left pattern block 1 and the right pattern block 2 are symmetrical in appearance, but are staggered and arranged in a herringbone shape. The longitudinal pattern groove 4 cuts the left pattern block 1 and the right pattern block 2 left and right, so that the left pattern block 1 and the right pattern block 2 can reduce the increase in rolling resistance caused by the transverse pattern design while providing excellent traction performance of the tire, and improve the drainage performance while reducing the rolling resistance. At the same time, the left pattern block 1 and the right pattern block 2 are large pattern blocks with large areas, which improves the wear resistance. Due to the misalignment of the left pattern block 1 and the right pattern block 2, the transverse pattern groove 3 has a corner in the center of the tread, interrupting the transverse pattern groove 3 to form a discontinuous transverse pattern groove, which reduces noise.

[0028] like Figure 1 As shown, in other embodiments, a plurality of disconnected reinforcing ribs are provided in the transverse groove 3. It is understandable that the transverse reinforcing ribs connect the upper and lower left pattern blocks 1 or right pattern blocks 2 together, thereby enhancing the overall rigidity of the pattern blocks, reducing creep deformation of the pattern blocks, reducing abnormal wear of the pattern blocks, and reducing the rolling resistance of the tire.

[0029] like Figure 1 As shown, in other embodiments, the reinforcing ribs include, from the center of the tread to the outside, two e1 reinforcing ribs 5, two e2 reinforcing ribs 6 and two e3 reinforcing ribs 7. It can be understood that there are a total of 6 reinforcing ribs in the transverse groove 3, two e3 reinforcing ribs 7 are located on both sides of the transverse groove 3, and two e1 reinforcing ribs 5 are located in the center. The 6 reinforcing ribs are all arranged at the straight section of the transverse groove 3, not at the corner.

[0030] like Figure 1 As shown, in other embodiments, the width of the transverse groove increases gradually from the tread center to the sidewall. It can be understood that, at the same time, the width x of the e1 reinforcing rib is less than the width y of the e2 reinforcing rib and less than the width z of the e3 reinforcing rib, and yx>1, zy>1.

[0031] like Figure 1 As shown, in other embodiments, it also includes:

[0032] The zigzag steel groove 8 is located on the left tread block 1 and the right tread block 2. The zigzag steel groove 8 can effectively improve the adhesion of the tire on a wet road surface, destroy the water film formed between the tire and the water-logged road surface, effectively drain the water in the contact area, and improve the anti-slip performance of the tire.

[0033] like Figure 1 As shown, in other embodiments, the tread includes: a short pitch S and a long pitch L in the circumferential direction. It can be understood that the tire tread pitch includes two different sizes. In this embodiment, the difference between the long pitch L and the segment pitch S is 3-5 mm, and the ratio of the long pitch L to the short pitch S is an irrational ratio. The variable pitch design plays a role in reducing pattern noise.

[0034] like Figure 1 As shown, in other embodiments, both ends of the transverse groove 3 extend to the lower side of the shoulder. The open shoulder design extends the length of the transverse groove 3, increases the heat dissipation of the tire shoulder, and improves the tire durability. The presence of the groove extending to the shoulder can also improve the vulcanization efficiency of the tire shoulder and the tire traction performance.

[0035] like Figure 2 As shown, the utility model also provides a trailer tire, which also includes a profile, on which the ratio of the running surface width b to the section width B is 0.85

[0036] like Figure 2 As shown, in other embodiments, the ratio of the vertical distance G from the tire shoulder to the inner contour to the vertical distance G1 from the tire crown center to the inner contour is between 1.2-1.35. This embodiment makes the tire crown force more uniform and can reduce the heat generation of the tire shoulder.

[0037] like Figure 2 As shown, in other embodiments, the shoulder includes a vertical segment A and an arc segment. In this embodiment, the length of the vertical segment A is greater than 5 mm, and in the arc segment, the arc of the lower radius R1 of the outer contour shoulder is tangent to the vertical length A and the upper sidewall arc. When the inner contour g of the tire and the arc radius R2 of the upper sidewall remain unchanged, the vertical distance G from the shoulder to the inner contour and the vertical distance F from the crown parting position to the inner contour curve can be reduced, thereby reducing the heat generation of the tire shoulder and making the tire more durable.

[0038] ​Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
