By changing the tread profile 2 of the tire, the tread profile 2 of the tire is set to only comprise a first section of crown arc 21 and a second section of crown arc 22, the relationship of 1.23-1.ltoreq.L2/L1-1.49 exists between the horizontal width L1 of the first section of crown arc 21 and the horizontal width L2 of the second section of crown arc 22, the relationship of 0.39-1/TDW-0.46 exists between the horizontal width L1 of the first section of crown arc 21 and the tread width TDW, the reasonable distribution of the widths of the first section of crown arc 21 and the second section of crown arc 22 of the tire is realized, the reasonable distribution of the tread material of the whole tire is further realized, the sufficient growth of the shoulder of the tire is ensured when the tire is inflated, the deformation of the shoulder is controlled within a reasonable range in the running process of the tire, and the uniform ground contact pressure distribution of the tire is ensured.
Referring to fig. 2, when the load factor of the tire is reduced to 80% during running of the tire, the footprint of the tire according to the present invention is substantially identical to the footprint of the tire middle portion of the tire shoulder 1, as compared to the conventional tire, and the footprint of the tire according to the present invention is more uniform in the ground pressure distribution.
Further, for a comparison of the contact pressure of a tire according to the present invention with a tire conventionally designed in the prior art when the load factor is reduced to 80%, refer to the following table one:
by comparing the tire of the design scheme with the tire of the conventional design scheme, the average ground contact pressure of the tire is smaller than the ground contact pressure of the tire of the conventional design scheme in the running process of the tire, and meanwhile, the linear standard deviation and the shoulder pressure deficiency of the tire of the design scheme are respectively far smaller than the linear standard deviation and the shoulder pressure deficiency of the tire of the conventional design scheme.
Referring to fig. 3, when the load factor of the tire is reduced to 100% during running, the footprint of the tire according to the present invention is substantially identical to the footprint of the tire center portion of the tire shoulder 1 as compared to the tire of the conventional design, and the footprint of the tire according to the present invention is also more uniform than the footprint of the tire of the conventional design.
Further, comparing the tire according to the present invention with the tire conventionally designed in the prior art, the contact pressure at the time of the load factor reduction to 100%, please refer to the following table two:

In summary, by arranging the tread of the tire to have a structure including only two end crown arcs, and making the relationship of 1.23L 2/L1 1.49 between the horizontal width L1 of the first segment crown arc 21 and the horizontal width L2 of the second segment crown arc 22, and making the relationship of 0.39L 1/TDW 0.46 between the horizontal width L1 of the first segment crown arc 21 and the tread width TDW, the tire of the present invention has more uniform ground contact pressure distribution compared with the tire of the conventional design.
When the proportion relation between the horizontal widths of the first crown arc and the second crown arc and the proportion relation between the two sections of crown arcs and the tread width are exceeded, the ground contact stress of the tire is not uniformly distributed, the phenomenon of asynchronous abrasion between the middle part of the tire and the shoulder part of the tire is caused, and abnormal abrasion such as uneven abrasion of the tire is caused. And ultimately results in a decrease in the overall range of the tire.
By arranging the tread of the tire to only comprise the structures of the crown arcs at the two ends, the relationship of 1.23-L2/L1-1.49 exists between the horizontal width L1 of the first section crown arc 21 and the horizontal width L2 of the second section crown arc 22, the relationship of 0.39-L1/TDW-0.46 exists between the horizontal width L1 of the first section crown arc 21 and the tread width TDW, and the relationship of 0.97-1.03 exists between the length of the grounding trace of the tire shoulder 1 and the length of the grounding trace of the middle section, so that the uniform abrasion of the tire is ensured, and the driving mileage of the tire is greatly improved.

By controlling the proportional relation of H1/H2 or H2/H3 or simultaneously controlling the proportional relation of H1/H2 and H2/H3 within a reasonable range, the shoulder of the tire can be ensured to expand uniformly during inflation, and further the ground contact stress of the tire is ensured to be uniformly distributed and the tire is uniformly worn during running.
When the ratio of H1/H2 exceeds the range of 0.87-0.97, or the ratio of H2/H3 exceeds the range of 0.70-0.78, or the ratio of H1/H2 and H2/H3 exceeds the respective ranges, the shoulder parts of the tire are not uniformly inflated, the shoulder parts 1 of the tire are not sufficiently grown, the ground contact patch of the shoulder parts 1 of the tire is smaller than the ground contact patch of the middle part of the tire in the running process of the tire, particularly in the condition of insufficient load factor, the stress distribution of the tire is uneven in the running process of the tire, abnormal abrasion occurs, and the running mileage of the tire is finally affected.
More than four circumferential main grooves 4 extending along the circumferential direction of the tire are formed in the tread.
The axial main groove arranged on the tread of the tire is mainly used for draining water in rainy days and meets the requirements of the wheel platform when the wheel platform runs in rainy days.
