A dynamic wheel balancing machine includes a rigid frame (11) and means (16) for supporting and rotating a vehicle wheel/tire assembly (14). The balancing machine further includes means (104) for detecting force variation in the wheel/tire assembly as well as means (100, 101) for detecting out of round portions of the rim and means (18) designating where the tire should be rotationally located with respect to the out of round portions of the rim to establish optimum ''roundness'' to the wheel/tire assembly. The rigid frame carries a bead breaker assembly (160) for use in raising the tire from its associated rim. The bead breaker assembly serves to readily permit the tire to be repositioned by rotating same on the rim to the portion designated as the preferred position to establish the optimum roundness. |
