ABSTRACT:
A method of setting a distance between upper and lower rims mounted on upper and lower spindles in a tire uniformity machine. The upper and lower rims under a superposed condition are first laid on an arm. Then, the arm is lifted or lowered until the upper rim reaches a desired upper position on the upper spindle. Then, the upper rim is fixed from an inner circumference thereof to the upper spindle at the desired upper position by an upper locking device. Then, the arm is lowered until the lower rim reaches a desired lower position on the lower spindle. Then, the lower rim is fixed from an inner circumference thereof to the lower spindle at the desired lower position by a lower locking device. Accordingly, a distance between the upper and lower rims can be set easily and quickly in a simple operation without using a spacer or the like.
