ABSTRACT:
A PCI main body includes two sets of gripping mechanisms and is rotatable about a horizontal axis, and a loader for detachably gripping an outside rim of the PCI and which is swingable in a horizontal plane. A vulcanized tire is received on the outside rim of the loader externally of the PCI main body, the loader is rotated to a position underneath the PCI main body, the tire and the outside rim are locked to the main body, a tire is seated on and fixed between an inside rim and the outside rim, compressed fluid is fed to the inside of the tire, and the PCI main body is rotated. Accordingly, a degree of precision in the concentricity between the respective rims can be maintained, a remote operation is possible, and the rims can be exchanged in a short period of time. Also, in addition to the above-mentioned features, a slide mechanism causes a support member for the outside rim to retreat upon rotation of the loader. Thus, the stroke of a rim interval adjusting screw can be relatively short.
