The invention relates to a tyre made of rubber material which comprises a tread (12) and two sidewalls (14) defining said tread, at least one of the sidewalls comprising at least one texture (16) in contrast with the remainder of said sidewall. The texture is divided into a plurality of patterns (18), (20) that are adjacent and have an identical outer shape. All or part of the patterns comprise a plurality of texture elements arranged so as to form in the pattern a plurality of rows extending in the same extension direction. For a predetermined pattern of said texture, the rows of texture elements of each pattern adjacent to said predetermined pattern have a different extension direction from the rows of texture elements of said predetermined pattern. The brightness of said non-textured sidewall remainder is at least 5 units higher than the brightness of the patterns of said texture.
