Provided is an automatic tire valve insertion method for tubeless tire, in which a tire valve can be smoothly inserted into a valve hole of a wheel without entailing damage to the tire valve, wheel, push rod, etc. even though the position of the valve hole varies in the radial and width directions of the wheel. In the tire valve insertion apparatus, the valve hole of the wheel being rotated is detected, the wheel is stopped at a predetermined position by braking, and the tire valve is inserted into the valve hole by means of the push rod of a valve press-fitting device. A light emitting element for emitting a detection light to be transmitted through the valve hole and a light sensing element for receiving the detection light are arranged facing each other across the rotating wheel. The light emitting and sensing ranges of these elements are elongated in a direction perpendicular to a circular path of movement of the valve hole.
