Tires with non-black tread grooves

A pneumatic tire comprising a black colored tread with at least one colored groove wherein the top surface of the tread designed to be ground-contacting is essentially free of non-black color. A non-black component is placed over the tread strip and covered with a thermoformable film prior to forming the groove pattern. After vulcanization, the film is removed, and the tread lugs buffed free of color, if necessary, thereby forming a tire having color localized in the tread grooves.
