ABSTRACT:
An air pressure information display device of a vehicle tire has a normal air pressure storage module (10a) for storing a normal air pressure of a tire corresponding to a tire temperature, an excessive/deficient amount detection module (10b) for detecting the excessive/deficient amount from the normal air pressure on the basis of the stored normal air pressure, and air pressure information detected by an air pressure information detection module (6-9), and a display control module (10c) for controlling a display (11) to display the detected excessive/deficient amount. Hence, since the user is informed of the excessive/deficient amount from the normal air pressure, he or she can appropriately determine an air pressure state of a tire even when he or she does not recognize the normal air pressure.
