Abstract
Abstract Rubber areas of a tire having electrical conductivity are used to transmitignals to an integrated circuit embedded within the thickness of the tire without relying on an inductive or capacitive coupling. Rather, an electric signal from an identification device is conducted to the integrated circuit through a first electrically conductive area of rubber such as a bead cover and/or the tire tread, and a responsive signal is returned to the identification device through a second electrically conductive area.
