ABSTRACT:
A method and an apparatus for fitting bead portions of the tire onto a wheel substantially uniformly and at the same time for filling inner pressure into the tire. A wheel cap-shaped jig in the form of a disc is arranged on the side surface of the wheel. The periphery of the wheel cap-shaped jig progressively reduces outwardly in the rotating axial direction of the wheel. The tire is then obliquely arranged on the wheel through the wheel cap-shaped jig, and the bead portions are radially outwardly expanded along their circumferences so as to assemble onto the rim. An outer cylindrical member having an inclined annular end surface and an inner cylindrical member telescopically arranged in the outer cylindrical member are brought into air-tight contact with the rim and a side surface of the tire, respectively. While inner pressure is filled into the tire through the clearance between the wheel and the bead portion of the tire, the outer cylindrical member is lowered relative to the inner cylindrical member to bring the bead portions into close contact with the rim.
