A sidewall 4 for a tire, the sidewall 4 has an annular exterior surface having a first background pattern 20,30,40 formed by numerous ridges 22,32,42 interrupted by a plurality of contrasting surface patterns 21,31,41. The contrasting surface patterns 21,31,41 are preferably smooth but can be textured or grainy in appearance, it being most preferred that these surface patterns 21,31,41 be similar in texture but not in shape. The combination of the numerous linear extending ridges 22,32,42 and the plurality of surface patterns 21,31,41 create an irregular mosaic background pattern 20,30,40.
