Provided is a technique of quantifying a change in irregularity appearing in an acceleration signal of a tire and measuring a tread wear amount of the tire using the quantified change. A tire wear measuring apparatus according to an embodiment of the present disclosure includes: a signal receiver configured to measure an acceleration inside a tire with respect to an axial direction, which is a radial direction of the tire, at a plurality of points inside the tire; a broad pass filter configured to receive a measured acceleration signal from the signal receiver and perform filtering as a preprocessing on the acceleration signal to generate a processed signal; a signal analyzer configured to estimate a tread wear rate of the tire by quantifying an irregularity of the acceleration signal using the processed signal that is a signal filtered through the broad pass filter; a transmitter configured to receive analysis information, which is information on the tread wear rate of the tire, from the signal analyzer and transmit the analysis information; and a control module configured to receive the analysis information from the transmitter and generate a control signal for a vehicle on which the tire is installed.
