Abstract
A tire made of rubbery material having a sidewall includes a pattern formed on this sidewall. The pattern has a plurality of protruding elements, with the protruding elements having the form of spherical-cap portions having a radius, and, within the pattern, each protruding element interpenetrates with several adjacent protruding elements so that the distance between a tip of the protruding element and a tip of another adjacent protruding element is less than the diameter of the protruding element.
