ABSTRACT:
In order to improve running characteristics of an automobile wheel comprised of rim and respective tire fitted thereon and presenting spring qualities, a matching procedure is used to readjust the tire and rim in clearly defined positions relative to each other. Radial run-out effects both of rim and tire are so arranged in opposite directions as to reduce the resulting radial run-out of the wheel. The matching consists in detail of opposing resultant tire radial force variations mathematically calculated on the basis of non-uniform mass distribution in the contact area of the tire under load with differences in tire spring rate on the one hand and radial run-out of the rim on the other hand.
