Abstract
A method and apparatus are described for monitoring the condition of a rotating pneumatic tire on a moving vehicle. A plurality of magnetic studs are embedded into the body of a pneumatic tire at the selected points about the periphery thereof. A magnetic field sensor is mounted upon a non-rotating portion of the vehicle adjacent to the tire and is utilized to detect the magnetic field pulsations generated by the rotating plurality of magnetic studs. As the temperature of the tire increases, toward imminent failure, or tread separation, the heat generated will decrease the magnetic field associated with the magnetic studs. When the temperature increases to a selected point and the magnetic field decreases accordingly, a display device is utilized to generate a visual and/or audible indication of imminent tire failure.
