A tire state estimation system for determining pressure and tread depth of a tire (12) and a method for estimating tire inflation pressure and a tread depth of a tire (12) are disclosed. The system (10) comprises at least one tire (12) supporting a vehicle, the tire (12) having a tire ID (20); tire vertical mode measuring means for measuring a tire vertical mode frequency and generating tire vertical mode frequency data; tire torsional mode measuring means for measuring a tire torsinal mode frequency and generating tire vertical mode frequency data; tire identification means for generating tire-specific frequency mode coefficients using tire-specific identification data; and tire state estimation means for calculating an estimation of a tire wear state and inflation pressure based upon the vertical mode frequency data, the torsional mode frequency data and the tire-specific frequency mode coefficients.
