TIRE WITH HEAT TRANSFER RUBBER CONDUIT
First Claim
1. A pneumatic tire containing a heat conductive path where said heat conductive path is a heat transfer rubber conduit comprised of an individual, or a plurality of interfacially connected, heat conductive rubber tire component(s) wherein said heat transfer conduit extends from an internal portion of the tire to an external tire surface,wherein the rubber composition(s) of said heat conductive tire component(s) each contain about 10 to about 60 parts by weight of acetylene carbon black per 100 parts by weight of rubber (phr) contained in a said tire component.

Abstract
This invention relates to a tire which contains a pathway for transferring heat within a tire comprised of a heat transfer rubber conduit composed of at least one operational, physically functional, heat conductive tire component. In one embodiment, for a cured rubber tire, the heat transfer rubber conduit is provided as a pathway for transfer of heat generated within the tire to an external surface of the tire for dissipation of the conducted heat. In another embodiment, for an uncured rubber tire, the heat transfer rubber conduit is provided as a pathway to transfer heat applied to an outer surface of the tire to the interior of the tire. The heat conductive tire component(s) of the heat transfer conduit is/are each comprised of a heat conductive rubber composition containing acetylene carbon black. In one embodiment, the heat transfer rubber conduit is provided as a pathway for conduction of heat to or from a less heat conductive rubber component which adjoins at least one of such heat conductive rubber components.
