PROBLEM TO BE SOLVED: To provide a tire information detecting device capable of using a microcomputer that facilitates wiring processing of a signal cable, is inexpensive as a calculating unit, and has low processing capacity. SOLUTION: Tire information output sections 11-14 comprise detecting sensors 11a-14a of tire information, and radio transmitters 11b-14b wirelessly transmitting the tire information detected by the detecting sensors to a tire information detecting section 21. The tire information detecting section 21 comprises radio receivers 21a-21d for receiving and shaping the tire information transmitted wirelessly from the radio transmitters 11b-14b and a calculating unit 21e for detecting a tire state from the tire information transmitted from the radio receivers. The radio receivers 21a-21d have a transistor 33 for controlling the output of the tire information according to the level of an RSSI output outputted from the radio receivers, and output the tire information only while the level of the RSSI output exceeds a predetermined threshold.
