[0039] In the above solution, the edge thickness of the tire removal disc 6 is smaller than the thickness of the middle part thereof, so that the edge of the tire removal disc 6 can extend between the wheel hub and the rubber bead of the tire.

[0040] When in use, the bearing in the middle of the tire is passed through the positioning shaft 3, and the tire is fixed on the positioning shaft 3 through the fixing assembly 4, so that the positioning shaft 3 drives the tire to rotate together during the rotation process. After the fixing is completed, the spacing between the two tire-removing discs 6 on the box body 5 is adjusted so that the spacing between the two tire-removing discs 6 is greater than the width of the tire, and the angles of the two tire-removing discs 6 are adjusted so that the two tire-removing discs 6 are tilted upward, and the tilt angle is 45-75°, and the box body 5 is lowered in the vertical direction to the gap between the top of the two tire-removing discs 6 and the wheel hub and rubber bead of the tire, and the two tire-removing discs 6 are moved closer to each other again so that the tops of the two tire-removing discs 6 extend into the interior between the wheel hub and the rubber bead, and then the positioning shaft 3 is rotated to drive the tire fixed thereon to rotate together, and during the rotation of the tire, the rotating tire is peeled off by the two tire-removing discs 6 to separate the rubber bead and the wheel hub. When the rubber bead and the wheel hub of the tire are separated After that, stop rotating the positioning shaft 3. When the tire and the positioning shaft 3 are stationary, move any one of the tire release plates 6 to separate the moved tire release plate 6 from the tire, and adjust the angle of the other tire release plate 6 that is not separated from the tire, so that the top of the tire release plate 6 continues to rotate upward to reduce its inclination angle.
