The wheel (3) to be balanced is mounted on a rotatable shaft carried by two spaced bearings (6, 4) provided with force sensors ( 8, 10). Two standard weights are mounted on the wheel rim at two points spaced angularly apart. The sensors (8, 10) signal the forces exerted on the bearings by the rotation of the wheel equipped with said weights. The weights are then removed and a new measurement ofthe forces exerted on the bearings is made. The values and the positions of the correcting weights to be placed on the wheel are then determined from the characteristic relationship of the wheel-apparatus assembly obtained by comparison of the results of these two measurements.
