Abstract
In order to reduce the second harmonic of tangential force variation (TFV) of tire constituting one of factors of vibration in high speed running of a vehicle, a tire is rotated at a vibration generating speed and phase and amplitude of the second harmonic of TFV are measured and mass members M are provided or eliminated at two locations opposed to each other in the diameter direction on a circumference of the tire such that the measured second harmonic of TFV is canceled by the second harmonic of TFV caused by providing or eliminating the masses.
