Abstract
An apparatus for filling pressurized air into a tire includes a table for supporting thereon a tire mounted on a rim, an inner cylinder member air-tightly engageable with a flange of the rim, and an outer cylinder member air-tightly engageable with a side rubber of the tire and forming an air-tight space in cooperation with the inner cylinder member. The end face of the outer cylinder member air-tightly engageable with the side rubber of the tire is inclined to the rotating axis of the tire. Therefore, the bead portion of the tire needs only to get over the part of the hump of the rim positioned oblique relative thereto along its circumference little by little during filling pressurized air into the tire. As a result, the bead portion of the tire is only subjected to a little deformation and comes into close contact with the rim, the bead portion of the tire substantially uniformly closely contacts the rim. Therefore, the tire filled with pressurized air in this manner is in a complete state fully exhibiting its performance.
