PURPOSE:To remove a tire readily by holding a bead core with right and left pressing boards placed slidably to right and left directions on a base and by putting pressure force on the bead core with an oil jack. CONSTITUTION:Right and left sliding frames 4a and 4b having a base 1 and right and left pressing boards 6a and 6b, an oil jack 17, lock rods 20a and 20b, and so on are assembled at a work shop, and the lower faces of the right and left pressing boards 6a and 6b are secured to a tire bead section on the outside of the lug ring 25 of a tire. In the next step, the oil jack is placed on the central upper face of the base 1, and the lock rods 20a and 20b are engaged with the disc hole of a tire wheel. And then the oil jack is worked. The tire bead section is pressed thereby at the lower face of the right and left pressing board 6a and 6b resulting in removing the tire. This constitution serves to remove a tire readily.
