Abstract
At least one of ground contact pressure, shear stress and amount of skidding is measured at a measurement point on a tread surface of a tire. A sensor is arranged on a road surface and the measurement point is made to contact the sensor while the tire rotates. An initial position of the tire is set, where the measurement point is at a previously-set reference position and the tire is at a running start position on the road surface. The tire is made to run from the initial position to obtain a rotation angle difference θ between a tire rotation angle until the rotation axis of the tire passes over the arrangement position of the sensor and a tire rotation angle until the measurement point contacts the road surface. The tire is set at the initial position and rotated by θ without changing the running start position of the tire.
