Abstract:
A tire for operating use on motor-vehicle wheels, comprising:a pair of beads each of which is defined at an inner circumferential edge of the tire;a pair of sidewalls, each of which is in the form of an annulus extending in radial direction away from one of said beads;a tread band of substantially cylindrical conformation with opposite peripheral edges joined to the sidewalls at respective buttress areas, an outer surface of at least one of said sidewalls having an annular strip, formed on the sidewall in the form of a surface hollow of predetermined depth (""p"") relative to an overall general contour of the sidewall, the radial extension of which is defined between an inner peripheral edge disposed in the area between an associated bead and a maximum axial width circumferential line of the tire and an outer peripheral edge substantially coincident with the peripheral edge of the tread band at a corresponding buttress area;a plurality of substantially rectilinear ribs being formed on said annular strip and disposed consecutively in side by side relation, said plurality of ribs being circumferentially distributed and each being disposed within said annular strip and according to a given angle of inclination ("".varies."") included between 0.degree. and 90.degree. with respect to a radial straight line extending from the inner peripheral edge at a crossing point with the rib itself, substantially according to a direction intersecting at least the outer peripheral edge of said annular strip, said ribs having a height (""h"") less than the depth (""p"") of said surface hollow;informative inscriptions formed on said annular strip, said inscriptions being formed as solid non-striped characters on the annular strip and defined by a plurality of projections having smooth surfaces, emerging from said annular strip with a height greater than that of said ribs, and the height of said projections being greater than the depth of said surface hollow.
