PROBLEM TO BE SOLVED: To automatically perform the air pressure adjustment of a tire which is necessary for the safe running of a vehicle or to quickly detect the danger caused by the puncture of the tire and inform a driver of the danger by a simple constitution which is easily realized in a usual vehicle without a complex and large structure. SOLUTION: A pressurized-air cylinder 51 is disposed in the center of a tire wheel mounted with a tubeless tire and a pressurizing solenoid valve 52 for forming in the wheel an air supply path through which pressurized air supplied by the pressurized-air cylinder 51 is filled into the tire and a pressure sensor 41 for detecting the air pressure of the tire in the wheel are disposed. The solenoid valve 52 is controlled based on the output of the pressure sensor 41, whereby the air pressure of the tire is automatically optimized or a puncture is judged and an alarm is displayed. |
