[0025] The embodiment of the present utility model provides a trailer tire pattern and tire, which significantly improves the traction and wear resistance of the tire by designing the tread pattern and the tire body structure, and effectively increases the overall life of the tire. Figure 1 Schematic diagram of the structure of the trailer tire pattern according to the embodiment of the present invention. Figure 1 As shown, the trailer tire pattern of the present invention includes multiple longitudinal grooves extending in a zigzag pattern along the circumference of the tread, and blocks divided by these longitudinal grooves. The blocks located in the central area of ​​the tread are multi-directionally staggered zigzag blocks. These blocks include a central block 1 located at the centerline of the tread and intermediate blocks 3 located on either side of the central block 1. The central block 1 is staggered with multiple first transverse grooves 6, and the intermediate blocks 3 are staggered with multiple intermediate steel plates 10. The multi-directional, staggered zigzag blocks distributed along the circumference of the tire in the central area of ​​the tread effectively increase the tire's contact area with the road, improving grip and traction. This provides additional friction when driving on complex or slippery roads, preventing slippage and ensuring driving safety. Furthermore, the zigzag pattern evenly distributes pressure in multiple directions when the tire is subjected to stress, reducing localized wear on the tread and significantly improving the tire's wear resistance.

[0026] The trailer tire of the present invention has a first transverse groove 6 disposed on the edges of the central tread block 1 near the adjacent longitudinal grooves. The first transverse groove 6 is V-shaped, with one end connected to the adjacent longitudinal groove and the other end closed. Central steel plates 10 are disposed on the edges of the central tread block 3 near the adjacent longitudinal grooves. The central steel plates 10 include a first central steel plate 101 located near the inner side of the tread, a second central steel plate 102 located near the outer side of the tread, and a third central steel plate 103 located near the outer side of the tread. The first central steel plates 101 and the second central steel plates 102 are alternately disposed, with the second central steel plate 102 being longer than the first central steel plate 101. The third central steel plate 103 is in an inverted L-shaped structure, with its free end extending toward the second central steel plate 102. A semi-enclosed second transverse groove 7 is also disposed between adjacent third central steel plates 103 on the central tread block 3. The first transverse grooves 6 are angled, staggered along the tire's circumference. The first, second, and third central steel plates 101, 102, 103, and second transverse grooves 7 are located on either side of the central tread block 3, forming a zigzag pattern. The second and third central steel plates 102, 103, are staggered, non-contacting. The arrangement of multiple central steel plates 10 and transverse grooves divides the tire into a series of uninterrupted blocks.

[0027] The tread blocks of the trailer tire of the present invention also include shoulder blocks 5 located on both shoulders. The shoulders not only bear the lateral pressure of the tire during cornering, but also provide a certain amount of support for the tread. By increasing the shoulder contact area and the strength of the shoulder blocks, the tire can maintain better stability during cornering and starting, and prevent the tire from side slipping. At the same time, this reinforced structure can effectively prevent the tire from being damaged by external impact under harsh road conditions, thereby increasing the applicability and service life of the tire under complex road conditions. Specifically, a plurality of first shoulder steel plates 111 are spaced apart in the middle of the shoulder blocks 5, and the first shoulder steel plates 111 have an inverted L-shaped structure. An inclined third transverse groove 8 is provided on the crest of the edge of the shoulder block 5 near the center line of the tread, and the end of the third transverse groove 8 is connected to the middle of the first shoulder steel plate 111. A fourth transverse groove 9 and a second shoulder steel plate 112 are alternately provided on the side of the shoulder block 5 near the tread edge, and one end of the fourth transverse groove 9 is connected to one end of the first shoulder steel plate 111. By arranging the shoulder pattern blocks 5 with semi-closed structure shoulder steel sheets 11 and transverse grooves, the entire shoulder is formed into a continuous large pattern block, thereby increasing the contact area of ​​the shoulder and the pattern block strength.

[0028] The longitudinal grooves of the trailer tire of the present invention include side grooves 4 located on both sides of the tread and central grooves 3 located between the side grooves 4. The depth of the central grooves 3 is greater than the depth of the side grooves 4, and the width of the central grooves 3 is less than the width of the side grooves 4. The zigzag angle of the central grooves 3 is 6°-9°, and the groove wall angle of the central grooves 3 is 4°-6°; the zigzag angle of the side grooves 4 is 9°-11°, and the groove wall angle of the side grooves 4 is 6°-9°. By providing zigzag longitudinal grooves of different depths and widths on both sides of the tread, the water film effect can be effectively prevented, allowing the tire to maintain excellent traction on wet roads while significantly reducing the risk of hydroplaning during high-speed driving. The middle groove 3 located on the inner side of the tread is deeper, which is conducive to the rapid drainage of accumulated water, while the side groove 4 located on the outer side of the tread is shallower, which can further guide the water flow out of the tread. Through this multi-level longitudinal groove design, the tire has better drainage performance on rainy days and muddy roads, ensuring driving stability and safety.

[0029] The utility model also provides a tire having the aforementioned trailer tire pattern on its tread. The tire's inner liner is 2.0-2.4 mm thick, which is thicker than the inner liner of conventional tires. This increased inner liner thickness improves the tire's airtightness, reducing internal air loss and tire aging during long-term storage. The tire's bead utilizes a soft apex rubber with a low-hardness formula to absorb shock and minimize heat generation under high loads, extending tire service life while enhancing comfort.

[0030] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for which protection is requested in the present invention.
