ABSTRACT:
A pre-cured pneumatic rubber tire of open toroidal shape having a pre-cured rubber strip, comprised of at least one elastomer and which contains at least one electrically conductive element, adhesively bonded to an inner surface of the tire's cavity. The adhesive is an RTV polysiloxane comprised of an hydroxyl terminated (silanol terminated) polysiloxane and crosslinking agent. The adhesive is applied as a layer, or coating, thereof onto a surface of said pre-cured rubber strip, and/or onto a corresponding pre-cured inner surface of said pre-cured tire, and the resulting coated pre-cured rubber strip and inner surface of said pre-cured tire brought together with said layer of adhesive therebetween and the adhesive allowed to cure and thereby bond said strip to said tire inner surface. In one aspect of the invention, said strip is an annular pre-cured rubber strip bonded to the tire's inner surface in its crown region or to said tire inner surface circumferential with and close to the periphery of the tire's open cavity. In another aspect of the invention, said tire inner surface is of a textured configuration and optionally contains a thin coating thereon of a polysiloxane material. In a further aspect of the invention, said pre-cured rubber strip contains a transducer and/or microprocessor inductively and/or electrically connected to said electrically conductive element(s), for example a wire antenna, contained in said rubber strip.
