The tire bead is caused to generate bead faults due to the fact that the brake drum works to generate heat, and at present, the common solutions include assembling of the brake drum with heat dissipation holes, assembling of tubeless tires, watering cooling and the like. If the 13R22.5 tubeless specification mode is adopted, although the problem that the gap between the tire bead and the brake drum is small can be solved, the vacuum tire bead is limited by the structural limitation of the vacuum tire bead, the load-carrying capacity is insufficient, and the market using condition cannot be met.

As a further technical solution, the radius of the first circular arc segment R1 is 150mm, the radius of the second circular arc segment R2 is 360mm, the radius of the third circular arc segment R3 is 80mm, the radius of the fourth circular arc segment R4 is 25mm, and the radius of the fifth circular arc segment R5 is 9 mm.
As a further technical proposal, the tire body has an outer tire diameter D of 1120mm, a tire break width B of 313mm, a tire break height H of 278.1mm, a tire bonding diameter D of 563mm, and a tire bonding width C of 260 mm.
As a further technical scheme, the ratio of the lower breaking height H1 to the upper breaking height H2 of the tire body is 0.8-0.85.
As a further technical scheme, the ratio of the lower breaking height H1 to the upper breaking height H2 is 0.8391.
As a further technical scheme, a hexagonal steel wire ring formed by winding a plurality of steel wires is arranged at the bottom of the tire body, and an angle formed by the bottom edge of the hexagonal steel wire ring and the horizontal plane is 0 degree.
The utility model has the beneficial effects that: compared with products of 12.00R20 specification, the clearance between the brake drum and the wheel rim in the scheme of the utility model is enlarged, thereby not only effectively improving the heat dissipation condition of the brake drum and reducing the generation of tire bead part faults; compared with the product of the specification of 13R22.5, the tire bead load-carrying capacity is further enhanced by the design of the tire bead structure and the profile type; at the same time, this design allows for a reduction in tire weight: not only saves cost, but also is beneficial to the heat dissipation of the tire body, and further reduces the generation of tire faults.
