ABSTRACT:
A pneumatic tire includes a strip of white rubber which is added to the otherwise black tire sidewall. The strip is molded separately from the other tire components and is added to the unvulcanized tire at the tire curing press. The strip is pressed into a recess in the sidewall forming surface of the upper tire mold half by a carrier ring which swings into the tire press with the green tire loader. The strip of white rubber is then affixed to the tire during molding of the tire.
