By setting the steel ladle inner end 7, tire strength is increased. An air bladder 8 is set between the triangular rubber 6 and the tire outer end 2, and an air intake mechanism 9 is set on the air bladder 8. A steel wire ring 10 is set on the surface of the tire outer end 2, and the steel wire ring 10 contacts the air bladder 8.

[0019] Please see Figures 1-2The air intake mechanism 9 includes an air intake pipe 91, which is fixedly connected to the airbag 8. The air intake pipe 91 passes through the outer end 2 of the tire, the inner nylon reinforcement 5, and the inner end 7 of the steel ladle. A retaining ring 92 is fixedly connected inside the air intake pipe 91. A plug 93 is slidably connected inside the retaining ring 92. A sealing gasket 94 is fixedly connected to the outer side of the plug 93. The sealing gasket 94 contacts the retaining ring 92. By setting the sealing gasket 94, the sealing between the plug 93 and the retaining ring 92 is increased. A sliding pin 95 is slidably connected inside the air intake pipe 91. A support ring 96 is fixedly connected to the end of the sliding pin 95. A spring 97 is set inside the air intake pipe 91. One end of the spring 97 is fixedly connected to the plug 93, and the other end of the spring 97 is fixedly connected to the support ring 96. 97, which makes it easy for the plug 93 to be reset.
