Abstract:
A pneumatic tires (20FL, 20FR, 20RL, 20RR) each having a plurality of air chambers disposed therein along a tread width direction. An internal pressure control device (100) includes a sensor unit (120) configured to inform a controller (110) that the four-wheel automobile (10) is going as being displaced in the leftward or rightward direction; and the controller (110) configure to change the internal pressures of the plurality of air chambers on the basis of the instruction outputted from the sensor unit (120).
