Abstract:
This invention relates to a pneumatic rubber tire which contains at least one electrically conductive cord extending from an external outer surface of its wheel-rim mounting surface rubber component to an internal electrically conductive tread base layer rubber component to provide a path of least electrical resistance, namely an electrically conductive path, between the outer tire wheel-rim mounting surface and the internal tire tread base layer. The electrically conductive cord is comprised of at least one electrically conductive metal filament (e.g. metal filament, carbon fiber or combination of metal filament and carbon fiber) spirally wound around a centrally disposed core of at least one organic fiber.
