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.
A pneumatic tire having an integrated circuit transponder located within the structure of the tire for use in tire identification and pressure data transmission, the tire having two spaced beads comprising steel wire, the tire having a tread, sidewalls, an innerliner and a plurality of plies at least one of which is a continuous ply extending between the annular tensile member, respective ends of the continuous ply being turned axially and radially outwardly about the bead, the transponder having an antenna and being able to transmit an electrical signal in response to an oscillating electric or magnetic field emanating from a source in contact with or spaced from the tire, the pneumatic tire, and transponder being characterized by:
