Abstract
A wheel-state obtaining system includes: air pressure sensors each provided for a corresponding one of a plurality of wheels to detect an air pressure of a tire of the wheel; and temperature sensors each provided for a corresponding one of the wheels to detect a temperature of an inside of a tire of the wheel; and a controller. The controller obtains a temperature conversion air pressure, which is the air pressure of each tire when the temperature is a set temperature, based on a detected air pressure and a detected temperature. When a reduction amount of the temperature conversion air pressure of one of the wheels is greater than a reduction amount of the temperature conversion air pressure of each of other wheels except the one of the wheels, the controller determines that the air pressure of the tire of the one of the wheels is in an abnormal state.
