  • the tyre In use, when removing a tyre in the field, the tyre is first deflated. The front and rear beads of the tyre are then broken. Tyre handler grabs are then engaged with the tyre and the tyre is pushed away from the flange 16. The tyre handler grabs are then clamped onto the flange 16 and manipulated with conventional equipment until the flange 16 bears against the inner shoulder 72 of the bead seat band 14. The appropriate number of clamping apparatus 10, 80 are then engaged, in the manner described above, with the bead seat band 14 and the flange 16. The resultant flange and bead seat band assembly is then removed from the rim with the tyre handler.
  • the tyre can then be safely removed.
