[0004] The purpose of this utility model is to solve the above-mentioned problems existing in the prior art, and to propose a four-line tire pattern for light trucks. Through the arrangement of the tread pitch and the design of the tread structure, it provides the vehicle with a faster driving response, while improving grip, ensuring stable starting and braking performance, achieving low noise and high mileage performance, bringing reliable safety protection to the vehicle owner, and meeting market demand.
[0005] The technical solution of this utility model is:
[0006] A four-line tire tread pattern for light trucks includes a left tread pattern group and a right tread pattern group. The left tread pattern group includes a first tread block, a second tread block, and a shoulder tread block. A first tread groove is provided between the first tread block and the second tread block. The first tread groove is an equally divided folded groove. A second tread groove is provided between the second tread block and the shoulder tread block. The second tread groove is a straight groove. The width of the second tread groove is 0.5 to 1 mm greater than the width of the first tread groove.
[0007] The right-side pattern group is centrally symmetrical to the left-side pattern group. The first pattern block has a thin steel sheet that runs horizontally through it. The thin steel sheets on the two sides of the first pattern block are staggered. The second pattern block has adjacent horizontal and vertical steel sheets. The angle between the horizontal steel sheet and the horizontal line is 20-25°, and the angle between the vertical steel sheet and the horizontal line is 100-110°. The vertical steel sheet adopts a stepped design, with its center depth being 0.4-0.6 times the depth of the pattern groove, and the depth of the steps on both sides being 0.2-0.4 times the depth of the pattern.
[0008] Furthermore, the width of the transverse steel sheet is 0.7-1 mm and the depth is 2.5-3.5 mm, and the width of the longitudinal steel sheet is 0.7-1 mm.
[0009] Furthermore, the right tread pattern group and the left tread pattern group are arranged symmetrically with a staggered arrangement around the center line of the tread, and the staggered distance between the two sides is 1 / 4 of the pitch width.
[0010] Furthermore, the first patterned groove is bent at a small angle of 7° to 9° and its width is 8 to 9 mm, while the width of the second patterned groove is 8.5 to 9.5 mm.
[0011] Furthermore, the bottom of the first patterned groove is provided with alternating circular and zigzag-shaped stone blocks, the direction of which is consistent with that of the first patterned groove; the height and diameter of the circular stone blocks are both 2-3 mm, and the height and width of the zigzag stone blocks are both 2-3 mm; the bottom of the second patterned groove is provided with rectangular stone blocks arranged at equal intervals, the width and height of which are both 2-3 mm.
[0012] Furthermore, the area of the shoulder tread block is 1.25 to 1.35 times the area of the first tread block, and the area of the second tread block is 1 to 1.15 times the area of the first tread block; the saturation of the tire tread is 75%-80%.
[0013] The beneficial effects of this utility model are:
[0014] The tire tread design of this utility model features a more reasonable distribution of grooves, better ground contact, and more even force distribution, avoiding uneven wear and thus increasing tire mileage. The tread design with two straight grooves and two zigzag grooves gives the tire superior directional performance and good anti-slip performance, resulting in higher safety performance in actual use.
[0015] This invention improves tire performance and reduces tire weight through optimized contour and tread design, thereby enhancing the tire's cost-effectiveness and playing a more positive role in mileage, service life, and safety. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0021] like Figure 1 As shown in the figure, this utility model relates to a four-line tire tread pattern for light trucks, including a left tread pattern group and a right tread pattern group. The right tread pattern group is centrally symmetrical to the left tread pattern group, that is, the right tread pattern group is obtained by rotating the left tread pattern group by 180°. As can be seen from the figure, the entire tire tread pattern adopts an asymmetrical design on both sides. The right tread pattern group and the left tread pattern group are offset symmetrically around the center line of the tire tread, with a 1 / 4 pitch width offset between the two sides. This ensures more uniform rigidity of the center block, guarantees wear resistance, and reduces noise.
[0022] The left-side tread pattern group includes a first tread block 1, a second tread block 2, and a shoulder tread block 3. A first tread groove 4 is provided between the first tread block 1 and the second tread block 2, and a second tread groove 5 is provided between the second tread block 2 and the shoulder tread block 3. The overall tire tread pattern adopts a four-groove design. The width of the second tread groove 5 is 0.5 to 1 mm wider than the width of the first tread groove 4. Specifically, it can be any value within the range of 0.5 mm, 0.8 mm, 1 mm, or 0.5 to 1 mm. This design makes the tire contact with the ground more even and effectively avoids the occurrence of groove cracks.
[0023] Furthermore, the second patterned groove 5 adopts a straight groove design with a width of any value within the range of 8.5mm to 9.5mm, which can give the pattern good drainage performance. The first patterned groove 4 adopts an equally divided folded groove with a bending angle of any value within the range of 7° to 9°, and its width is any value within the range of 8 to 9mm. This design can not only ensure drainage performance, but also improve the controllability of the pattern.
[0024] The first tread block 1 has a thin steel sheet 8 that runs transversely through the tread block, with the thin steel sheets 8 on both sides of the first tread block 1 arranged in a staggered manner. The second tread block 2 has a connecting transverse steel sheet 6 and a longitudinal steel sheet 7. The transverse steel sheet 6 is designed with an angle of 20° to 25°, that is, its angle with the horizontal line is any angle within the range of 20° to 25°. Furthermore, the width of the transverse steel sheet 6 is any width value within the range of 0.7 to 1 mm, and the depth is any depth value within the range of 2.5 mm, 3 mm, 3.5 mm, or other depth values within the range of 2.5 to 3.5 mm. The presence of this transverse steel sheet 6 is beneficial for heat dissipation from the tread and also for lateral water drainage from the tread, improving the tire's wet grip performance. The longitudinal steel sheet 7 is designed with an angle of 100° to 110°, that is, its angle with the horizontal line is any angle within the range of 100° to 110°. Furthermore, the width of the longitudinal steel sheet 7 is any width value within the range of 0.7 to 1 mm.
[0025] like Figure 2 As shown, the longitudinal steel sheet 7 adopts a stepped design. Its center depth (middle 1 / 2 depth) is approximately 1 / 2 of the tread groove depth, specifically, it can be 0.4, 0.5, 0.6, or any other multiple within the range of 0.4 to 0.6 of the tread groove depth. The depth of the two side steps (two side 1 / 4 depths) is approximately 1 / 3 of the tread depth, specifically, it can be 0.2, 0.3, 0.4, or any other multiple within the range of 0.2 to 0.4 of the tread groove depth. The presence of this longitudinal steel sheet 7 facilitates tread heat dissipation and improves the tire's wet grip performance. In a specific embodiment, the width 'a' of the middle portion is 14, the height 'b' of the upper step is 3, and the height 'c' of the lower step is 3; furthermore, each end of the stepped steel sheet adopts a rounded arc design.
[0026] In this specific embodiment, the bottom of the first patterned groove 4 is alternately arranged with circular cobblestones 10 and zigzag cobblestones 9, wherein the direction of the zigzag cobblestones 9 is consistent with the bending direction of the first patterned groove 4. The height of the circular cobblestones 10 is any height within the range of 2-3 mm, and its diameter is any value within the range of 2-3 mm. The height and width of the zigzag cobblestones 9 are the same, and are any value within the range of 2-3 mm. The bottom of the second patterned groove 5 is provided with rectangular cobblestones 11 arranged at equal intervals. The width and height of the rectangular cobblestones 11 are the same, and are any value within the range of 2-3 mm. The above-mentioned design of cobblestones of different shapes and sizes can effectively prevent groove cracking caused by stones trapped in the patterned groove.
[0027] Furthermore, the area of the shoulder tread block 3 is 1.25 times, 1.30 times, or 1.35 times the area of the first tread block 1, or any multiple within the range of 1.25 to 1.35. The area of the second tread block 2 is 1.0 times, 1.1 times, or 1.15 times the area of the first tread block 1, or any multiple within the range of 1 to 1.15. A reasonable ratio allows for a better match in the rigidity of each tread block, ensuring more even stress on the tire tread during driving and preventing uneven shoulder wear and crown wear at different wheel positions, thus avoiding shoulder and crown gaps in the early stages of tire use. Simultaneously, the tread saturation is set at 75%-80% to improve the tire's wear resistance.
[0028] The tire's shoulder features a large sidewall design with a depth ranging from 2.5mm to 4mm, which helps reduce tire weight and improve fuel economy, while also enhancing heat dissipation, improving tire durability, and extending tire lifespan.
[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, alterations, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
