Abstract
A method for monitoring an operating condition of a vehicular tire. The method includes providing magnetized areas in the tire and magnetic field sensors on the chassis of the vehicle. Rotation of the tire produces magnetic field pattern signatures which characterize the tire's materials, construction and deformation conditions. Changes in magnetic field pattern signatures from a baseline are indicative of impending abnormalities in tire integrity that can be recognized in advance to forestall vehicle accidents attributed to tire faults.
