A system for estimation of a depth of a tread of a tire supporting a vehicle includes a processor in electronic communication with an electronic control system of the vehicle. A wheel speed signal processing module is in electronic communication with the processor, receives measured wheel speed signals, and generates processed wheel speed signals from the measured wheel speed signals. A Fast Fourier Transform computation module receives the processed wheel speed signals and generates a Fast Fourier Transform curve. A summation module selects a predefined range of the Fast Fourier Transform curve, generates a reference curve from the predefined range of the Fast Fourier Transform curve, and determines a sum of residuals between a real-time Fast Fourier Transform curve and the reference curve. A regression model determines an estimate of tire tread depth from the sum of residuals.
