1. A method for monitoring an operating condition of a vehicular tire, comprising:
- providing at least one magnetized area in a tire of a vehicle;
providing at least one magnetic field sensor at a predetermined location on a vehicle chassis;
recording at least one time period between passing of the at least one magnetized area and the at least one magnetic filed sensor during rotation of the vehicular tire;
computing a magnetic field pattern that is characteristic of the vehicular tire'"'"'s materials, construction and deformation conditions; and
calculating the operating condition of the vehicular tire wherein the operating condition includes tread, sidewall and bead conditions.

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.
