1. A system for monitoring at least tire tread wear of a vehicle tire, comprising:

  • a sensor which senses at least one of radial and lateral acceleration of a tire to provide acceleration signals;

    a driver information display; and

    at least one processor, responsive to acceleration signals from the sensor, which determines at least one resonance frequency of at least one of the radial and lateral acceleration of the tire, compares the determined at least one resonance frequency to at least one stored frequency, determines the tire tread wear on the basis of the comparison, and provides an information signal indicative of tire tread wear which is transmitted to the driver information display.
