An indirect tire pressure monitoring systems (TPMS) and methods that utilize anti-lock braking system (ABS) sensed signals coupled to circuitry and/or controllers to process the sensed signals using a multidimensional resonance frequency analysis (MRFA) technique. Additional information from other sensed signals or stored data settings for non-tire variables and parameters can be incorporated into the MRFA. Thus, an indirect TPMS comprises at least one signal from an ABS, such as a wheel speed signal, and an electronic control unit (ECU) that processes the at least one signal from the ABS using at least one MRFA technique. The MRFA uses a spectral analysis of tire vibrations as determined from the sensed ABS signals over different points in the spectrum that can reflect different vibration modes and different corresponding resonance frequencies.
