Abstract
Indicia of enhanced visibility for rubber articles, and particularly for tires, are formed by a series of substantially straight lineal projections of the same approximate cross section integral of the article. The projections are continuous within the configuration of each indicium. Each indicium may include raised borders and/or may in total be raised above the surface of the article immediately surrounding the indicium. The cross-sectional width of a projection is from about 30 percent to 70 percent of the distance between the longitudinal axes of adjacent projections. To further enhance visibility dirt-retaining projections may be employed.
