ABSTRACT:
A method and apparatus for checking the concentricity of a pneumatic vehicle tire that during operation has its beam portions mounted on the radially inner periphery of a wheel rim. The apparatus includes a two-part test rim, the two rim ring sections of which are axially movable. Disposed against the test rim is a tire that is to be checked, with this tire being manufactured with trapezoidally axially outwardly directed sidewalls, and with the tire being disposed against the rim ring sections in this trapezoidal form. Bead-receiving rings are moved axially from the outside against the axially moved-apart rim ring sections. These bead-receiving rings fold-over the sidewalls and bring them, in a rim-seating position, into contact against the rim ring section. The tire is secured in position between the rim ring sections and the bead-receiving rings.
