DEVICE AND METHOD FOR DETECTING ABNORMAL STATE OF TIRE

A device for detecting an abnormal state of a tire includes a wireless transceiver spaced apart from the tire and coupled to a vehicle, where the wireless transceiver transmits a radio signal to a ground surface and acquires delay information required to receive a reflected wave from the ground surface, and a control module that calculates a reference distance between the wireless transceiver and the ground surface based on the delay information, and detects an abnormal state of the tire, based on a reference distance change.
