1. A method of adjusting vehicle wheel alignment comprising the steps of:

  • placing a wheel of a vehicle, said wheel including a tire mounted thereto, on a tire driving surface on which a step of a predetermined height is formed at at least one place along a rotating direction in which the tire driving surface is driven by a rotational force;

    measuring variations in forces applied in the rotating direction of the tire driving surface and a rotation axis direction which is orthogonal to the rotating direction at the time the wheel passes over the step while the tire driving surface is being driven so that the wheel is rotated in a proceeding direction of the vehicle; and

    adjusting a positional angle of the wheel, on the basis of said measurements, such that a variation in lateral force generated by the tire when the wheel passes over the step is a minimum.
