ABSTRACT:
A tire testing machine having a rotatably but actuatably fixed upper rim, a rotatable lower rim assembly and a hydraulic cylinder for raising and lowering the lower rim to a desired position. The lower rim assembly has a resiliently-biased center pilot in the form of a cone that is engageable with a recess in the upper rim to center the lower rim with respect to the upper rim and to transmit rotational forces from the upper rim to the lower rim. The centering action of the pilot is assisted by a pair of mating spherical washers associated with the lower rim assembly.
