A rubber composition for a tire tread chimney component includes a sulfur-vulcanizable elastomer and an electrically conductive polymer. The rubber composition is further defined by an absence of electrically conductive carbon black. The sulfur-vulcanizable elastomer is selected from the group consisting of natural rubber, polybutadiene, polyisoprene, styrene butadiene rubber, nitrile rubber, and combinations thereof. The sulfur-vulcanizable elastomer and the electrically conductive polymer are substantially evenly mixed together. In the tire, and upon curing, the tire tread chimney component provides a dissipative pathway for static electricity from the tire to the ground in operation.
