An imbalance measurement machine for determining tire imbalance has a hollow shaft rotatably driven relative to a fixed hollow axle. A tubular air feed for filling the tire with air is centered within and rotates with the shaft to rotate the tire for determining imbalance. An air hose is connected to a rotational coupling disposed at an air feed end that faces away from the tire. Force transducers between the axle and a machine bed measure forces that occur there during operation. The air hose is attached not only to the rotational coupling but also to the axle, at a distance from the rotational coupling. An alternative embodiment omits the rotational coupling and fills the tire in the resting state of the shaft, via the air hose and the non-rotating air feed. Subsequently, the air hose is separated from the air feed, and the tire retains the supplied air.
