Abstract
Matching multiple wheel rims and tires based upon runout and force variation measurements using balancing equipment. Centering errors and mounting errors are also reduced or eliminated. The method includes adjusting the rotational positions of the tires with respect to the wheel rims to compensate for wheel rim run-out and wheel/tire assembly force variations. This is accomplished in one embodiment by sequentially mounting a plurality of wheel/tire assemblies on a spindle of a balancer, measuring the rim run-out for each assembly and the force variations for each assembly, marking each tire of each assembly to identify both the individual tire and the rotational position representing the first harmonic of the tire force variation at which each tire is mounted with respect to its wheel rim, removing each tire from its wheel rim, sequentially mounting the wheel rims with tires removed on the spindle of the balancer, measuring the rim run-out for each rim, and visually indicating to a user a preferred matching between the tires and the wheel rims to minimize assembly vibration.
