Abstract: A method and apparatus for examining a wheel of a vehicle is provided. A support roller assembly for supporting thereon the wheel rotatably is provided to be movable translationally as well as rotationally in a plane when unlocked. A cylinder actuator having a reciprocating movable rod is also provided. A wire is extended between the tip end of the rod and the support roller assembly. When the rod is located at its advanced position, the wire is slackened to establish a static examination mode of operation, in which the support roller assembly can move freely in a plane without constraints. Under this condition, the static characteristic of the wheel is measured and adjusted, if necessary. On the other hand, when the rod is located at its retracted position, the wire is under tension, and the cylinder actuator is operatively coupled to the support roller assembly whose movement is under constraints through the wire. Thus, a dynamic examination mode of operation is established.
