The application relates to the technical field of tires, in particular to a bearing wheel and a using method thereof, which comprises a tire composed of a first annular cylinder, a second annular cylinder and rubber blocks and a power shaft, the first annular cylinder and the second annular cylinder are both in the shape of 'L' in cross section and are slidably connected, the first annular cylinder, the rubber blocks and the second annular cylinder are connected with each other and form an annular air pressure cavity therebetween, the power shaft is arranged at the middle position of the air pressure cavity, a support adjusting part for connecting the tire is arranged on the outer surface of the power shaft, and a control part is further arranged on the second annular cylinder, the control part drives the first annular cylinder and the second annular cylinder to move relatively and controls the width of the rubber blocks; the position of the control cylinder is limited by the control blocks, the position of the movable shaft is limited by the limiting grooves, and then the maximum width of the tire is limited, the first annular cylinder and the second annular cylinder are prevented from being burst open when the tire is compressed, and the safety and the practicability are improved.
