Abstract
A tire tread sensing system includes a magnetic field sensor and a magnetic field source configured to magnetize magnetizable particles embedded in a tire tread. The magnetic field sensor is configured to measure a magnetic field strength associated with the magnetic field source and the magnetizable particles, and the magnetic field strength is indicative of a tire tread depth. Alternatively, the particles comprise alternating permanent magnets embedded in a tread portion of a tire.
