In order to obtain, in service, a reduced acoustic emission, the position of the true point of contact (P) of the wheel with the rail is determined, the distribution of the masses of the section of the rim and of the wheel center of the wheel is adjusted so that the point of contact (P), the center of inertia (G1) of the section of the rim and the center of inertia (G2) of the section of the wheel center are located on one and the same straight line (XX') perpendicular to the axis (YY') and the outline of the section of the wheel is adjusted so that the point (P) is a vibration node for the axial vibration modes of the rim. The invention applies particularly to wheels for high-speed trains.
