A method and apparatus for assembling a tire (T) on the rim of a wheel (W) and filling inner pressure in the tire. The wheel is fixed on a wheel table (1) in an airtight manner to the table. The tire is arranged on the wheel and a pawl (4a) is moved along the circumference of the wheel or the wheel on the table is rotated to arrange the bead portions of the tire around the rim of the wheel. An outer cylinder member (3) is brought into abutment against one of the bead portions to urge it toward the other bead portion and pressurized air is filled into the tire through a clearance between the wheel and the one bead portion of the tire to bring the bead portions into close contact with the rim of the wheel. Thereafter, pressurized air is further filled in the tire through the inflation valve of the wheel to the tire through the inflation valve of the wheel to maintain the inner pressure higher than the normal inner pressure and then the inner pressure is lowered to the normal inner pressure.
