A pneumatic tire includes a tread base comprised of a first material, a tread cap comprised of a second material, and a ring comprised of a third material. The tread cap is disposed radially outward of the tread base and in operational contact with a ground surface. The ring is disposed at least partially within the tread cap and extends radially away from the tread base. The ring has a stiffness in the radial direction greater than stiffnesses in the circumferential and lateral directions. The third material has a substantially lower hysteresis than the second material during operation of the pneumatic tire. The third material further provides an electrical conductivity path to the ground surface.
