PROBLEM TO BE SOLVED: To improve resistance to hydroplaning while maintaining controllability and stability and the ride comfort of a vehicle 3. SOLUTION: When a hydroplaning resistant internal pressure mode set by considering resistance to hydroplaning is selected, while the internal pressure of a main air chamber 19A of each front wheel tire 5L (5R) and each rear wheel tire 7L (7R) is maintained at a constant level, the internal pressure of one of an auxiliary air chamber 19B on one side in the tire width direction and an auxiliary chamber 19B on the other side in the tire width direction of each front wheel tire 5L (5R) and/or each rear wheel tire 7L (7R) is controlled so as to become higher than the internal pressure of the main air chamber 19A.
