Abstract
A portable test apparatus (and associated method) for measuring nonuniformity of a tire/wheel assembly in situ on a wheel bearing hub of a vehicle are characterized by a lightweight assembly of components including, in particular, a probe for monitoring deflections of a surface of the tire/wheel assembly during rotation of the tire/wheel assembly and producing an electrical output indicative of the surface deflections, and an indexing device for producing an electrical output indicative of the rotational position of the tire/wheel assembly during rotation thereof, the indexing device having an attachment mechanism for removable coupling to the tire/wheel assembly. A holder is provided for holding the probe adjacent the surface of the tire/wheel assembly to be monitored for uniformity, and an electronic processor is provided for receiving and processing the electrical outputs from the probe and indexing device to provide an output indicative of at least one parameter representative of the nonuniformity of the tire/wheel assembly.
