Abstract:
A method of matching a tire to a wheel rim of a wheel, the wheel being a bare wheel prior to mounting the tire thereon, the method comprising:mounting the bare wheel on a spindle of a wheel balancer; determining the run-out of the wheel rim; mounting a wheel/tire assembly on the balancer spindle, the wheel/tire assembly comprising the tire mounted on the bare wheel; determining tire force variation of the wheel/tire assembly; indicating to a user a relative rotational mounting position of the tire with respect to the wheel rim to minimize the tire force variation; repeating the previous steps with at least one additional wheel and wheel/tire assembly; calculating the force variations that would result from the mounting of each tested tire on each tested wheel; matching the tested tires with the tested wheels so that force variation for each resulting wheel/tire assembly does not exceed a redetermined level.
