<p>A method in which the alignment of a wheel can be easily adjusted in accordance with the characteristics of the tire, and in which a running stability appropriate for an actual road surface is obtained and a reduction in one-sided wear is achieved. A plurality of plate-like protrusions of a predetermined height are formed on the outer surface of an endless track at a predetermined distance apart in the direction of the rotation on which is rotated a wheel. When the endless track is rotated, the wheel is rotated on the tire driving surface and travels from the top surface of plate section over a step up climbing up onto the top surface of the protrusion. Next, from the top surface of the protrusion, the wheel travels over a step and descends back down onto the top surface of the plate section. This action is repeatedly executed. The longitudinal force and lateral force generated in the tire at this time are measured and a predetermined period which includes the time from when the tire is deformed as the wheel travels over the step until the tire rotates and returns substantially to its normal state is determined on the basis of the rate of change in the longitudinal force, and the wheel angle is adjusted so that the energy of the variation in the lateral force within the predetermined period is reduced. <IMAGE></p> |
