A new measuring method which enables quantitative force evaluation for the ride comfort analysis has been developed. The force transmitted from road surface to tire has been measured while the vehicle is running. The results of the measurement has shown that the force transmitted from road to tire has certain direction of action in side view, within the frequency range between 5 and 15 Hz. And the inclination angle of the direction of action has been found to be dependent on the vehicle velocity. As the application of the measuring technique, the optimal wheel center locus inclination angle in side view, has been studied. And the optimum angle has been confirmed to exist.
