Abstract
A pneumatic tire has an integrated circuit transponder which, upon interrogation by an external RF signal, transmits tire identification and tire pressure data in digitally-coded form. The transponder has an antenna adjacent and thereby coupled by electric or magnetic fields to an annular tensile member comprising a bead of the tire. The antenna has lead wires that preferably are positioned between the innerliner of the tire and its continuous carcass ply. The transponder thus is on the axially inner side of the reinforced carcass ply. A pressure transducer is within the transponder and is responsive, preferably through the innerliner material, to pressure within the tire. If the antenna is a coil, the coil is substantially planar in shape and parallel with the reinforced carcass ply. The transponder and pressure transducer also can be attached to the axially inner side of the innerliner.
