Abstract
Using a decor strip of white, or other contrasting, compound not greater than about 2 millimeters thickness, two ribs and an intervening annular groove lined with the strip are formed on a tire sidewall. The strip is cured integrally with the ribs and sidewall and in direct contact with the mold, without the customary overlay of black rubber. The tire so formed has no white rubber beneath any black rubber in the tire. The quantity of white compound required is materially reduced. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
