A tire wear state estimation system is disclosed, the system comprising at least one tire for supporting a vehicle; tire pressure measuring means affixed to the at least one tire for measuring tire inflation pressure and for generating tire inflation pressure data; tire vertical mode measuring means for measuring tire vertical mode frequency and for generating tire vertical mode frequency data; tire identification means for generating tire-specific frequency mode coefficients using tire-specific identification data; and tire wear estimation means for calculating an estimation of a tire wear state based upon the tire inflation pressure data, the vertical mode frequency data, and the tire-specific frequency mode coefficients. Also, a method of tire wear state estimation is disclosed, the method comprising: affixing a tire pressure measuring device to a vehicle-supporting tire; measuring a tire cavity inflation pressure using the pressure measuring device and generating tire inflation pressure data; measuring tire vertical mode frequency and generating tire vertical mode frequency data; generating tire-specific frequency mode coefficients using tire-specific identification data; and calculating an estimation of a tire wear state based upon the tire inflation pressure data, the vertical mode frequency data, and the tire-specific frequency mode coefficients. |
