Abstract
A tire tread may be formed by simultaneously extruding a tread cap formed of a first material and a tread base formed of a second material having a substantially different stiffness property than the first material. One tread element may have a strip of the second material extending from the tread base into the tread cap and, a second tread element may also have a strip of the second material extending from the tread base into the tread cap.
