A method for optimizing the running properties of a rotating belt of a weighing belt conveyor includes, for at least one rotation of the belt, determining a unique reference position on the belt. A force signal is determined in dependence on the movement of the belt with respect to the reference position during the at least one rotation. From this force signal, the course of a deviation of the force signal from a set value as a consequence of a disruptive force is determined. At least in correspondence with the direction of the determined deviation, the mass of the belt is increased or reduced at locations in dependence on the position of the belt with respect to the reference position

A load transfer function of a uniformity measuring apparatus in a second state, in which a tire to be measured is attached, is obtained using at least either a load transfer function or an acceleration transfer function measured in a step of measuring reference transfer functions and a natural frequency measured in a step of measuring a natural frequency. The obtained load transfer function is used to correct tire uniformity data obtained by performing a certain type of signal processing on a tire uniformity waveform.
