Uniformity correction procedure for tire in motor vehicle, involves specifying mass body based on amplitude and phase of secondary components, which is provided or deleted at two suitable places facing tire

摘要

A tire is rotated at oscillating generation velocity based on secondary components of tangential force variation (TFV) and phase and amplitude of the components is measured. A mass body (M) specified based on the phase and amplitude is provided or deleted at suitable places facing the tire direction, so that secondary components are reduced. The mass body is provided within the limits of 32.0-61.0 deg to the rotation direction during measurement of tire position.
