A tire side device includes a vibration detection unit that outputs a detection signal according to a magnitude of vibration of a tire, an air pressure detection unit that detects the tire pressure, a data acquisition unit that calculates a contact length of the tire with a road surface based on the detection signal and acquires a wheel load data that is a data related to the wheel load based on the contact length, and a data transmission unit that transmits a data related to the tire pressure and the wheel load data. A vehicle side device includes a receiving unit that receives data on tire pressure and wheel load data, a threshold setting unit that sets an alarm threshold for tire pressure based on the wheel load data, and an alarm determination unit that determines that the tire pressure has decreased when the tire pressure indicated by the data on the tire pressure decreases below the alarm threshold.
