A tire having a rubber body in which a steel cord is embedded, wherein a layer composed of ZnxCoyO is formed at the interface between the steel cord and the rubber body and x+y is 5/6 or more and 1 or less.
First claim
Opening claim text (preview).
The invention claimed is: 1. A tire having a rubber body in which a steel cord is embedded, wherein a layer composed of Zn x Co y O is formed at the interface between the steel cord and the rubber body and x+y is 5/6 or more and 1 or less. 2. The tire according to claim 1 , wherein the steel cord has a steel wire and a plating layer containing Cu and Zn provided on the steel wire and Co is contained in the plating layer. 3. The tire according to claim 2 , wherein Co is exposed on the surface of the plating layer of the steel cord. 4. The tire according to claim 1 , wherein Co is contained in the rubber body. 5. The tire according to claim 1 , wherein the layer composed of Zn x Co y O is at least partially in between a ZnO film and a copper sulfide layer. 6. A tire having a rubber body in which a steel cord is embedded, wherein the steel cord has a steel wire and a plating layer containing Cu and Zn provided on the steel wire, wherein Co is contained in the plating layer, wherein a layer of composition which is composed of Zn x Co y O is formed at the interface between the steel cord and the rubber body, wherein a ZnO film is formed between the rubber body and the plating layer, wherein a Co component contained in plating layer is oxidized in part under an environment of moist heat deterioration to form Co 2+ or Co 3+ and the composition is formed through the replacement with Zn 2+ in the ZnO film so as to balance the valency, and wherein x+y is 5/6 or more and 1 or less.
