A tire balancing machine in which the tire is mounted on an axle which is pivotally mounted relative to a road wheel while maintaining the axis of rotation of the tire parallel to the axis of rotation of the road wheel, the tire being spring loaded against the road wheel to simulate the weight load borne by the tire in normal use and the road wheel driven at a speed to rotate the tire at its intended operating speed, sensors being provided to measure the magnitude and location of the horizontal and vertical asymmetrical forces developed at the tire patch, the force measurements being utilized to determine the location and amounts of weight to be applied to the wheel rim to offset the asymmetrical forces generated by the tire in use.
