A number of reinforcing ribs 11 are provided on the inner side wall of the tire body 1. These reinforcing ribs 11 are integrally formed with the tire body 1, and the height is 1 / 4 of the height of the inner side wall of the tire body 1. The function of the reinforcing ribs 11 is to enhance the structural strength of the tire body 1 and improve the tire's load-bearing capacity and anti-deformation ability.

[0054] Shock-absorbing layer 2: Made of rubber, the ratio of the elastic modulus of two adjacent layers of elastic material is 1.2. The total thickness of the shock-absorbing layer 2 is 1 / 5 of the thickness of the tire body 1. Shock-absorbing holes 21 with a hole diameter of 2 mm are arranged in the shock-absorbing layer 2 and are evenly distributed. These shock-absorbing holes 21 can effectively absorb and disperse vibration energy and improve the shock-absorbing performance of the tire. In addition, a connection structure matching the tire body 1 is preset on the shock-absorbing layer 2 so as to be accurately connected with the tire body 1.

[0055] Adhesive layer 3: Adhesive with high and low temperature resistance is used, and carbon nanotubes accounting for 1% by weight are evenly dispersed in the adhesive. The function of the adhesive layer 3 is to firmly bond the shock-absorbing layer 2 to the tire body 1 to ensure that the shock-absorbing layer 2 will not separate from the tire body 1 during use of the tire.

[0056] Manufacturing formula: 50 parts of natural rubber, 20 parts of butadiene rubber, 30 parts of carbon black, 3 parts of zinc oxide, 1 part of stearic acid, 2 parts of antioxidant, 1 part of accelerator, and 1 part of sulfur.

[0078] Embodiment three:

[0079] Tire body 1: Made of rubber, the outer surface pattern of the tire body 1 has good anti-skid and drainage performance. The height of the reinforcing rib 11 on the inner side wall of the tire body 1 is 1 / 2 of the height of the inner side wall of the tire body 1, which greatly enhances the structural strength of the tire body 1 and enables it to withstand greater loads and impacts.
