A combination pneumatic tire and integrated circuit transponder for tire identification. The transponder (24) is located within the tire structure and is capable of transmitting an identifying digital signal in response to interrogation by an R/F electric field emanating from outside the tire (22). The transponder (24) then transmits the identifying signal, which is received, conditioned and demodulated. The tire (22) has a steel-reinforced component, such as an annular tensile member (36) in its bead or a steel-reinforced ply. The transponder (24) has first and second electrodes (61,62), the first of which is positioned such that the average spacing of this first electrode's surface from one of the steel-reinforced tire components e.g. from steel cord ply (32) is substantially less than the average spacing of the second electrode's surface from such component. The transponder (24) is capable of transmitting the electrical signal from the tire (22) both prior to and after its vulcanization, thus permitting identification and control of the tire (22) during its manufacture and after its distribution and use. |
