<p>An improved tire sidewall (12) for a tire (10) has an annular outer surface (11), the annular outer surface (11) having a design pattern having a first pattern (15) and a second pattern (17). The second pattern (17) is superimposed over a portion of ridges (20) of the first pattern (15). The improvement has the ridges (20) of the first pattern (15) within a sidewall sector (13) defined by parallel planes passing through a plane (T) parallel to the equatorial plane of the tire (10) and perpendicular to the axis of rotation of the annular tire sidewall (12) to form lines (21) all having the same slope (x/y). Preferably the ridges (20) have a substantially triangular cross section having an included angle of about 100° at the apex. The sectors (13A, 13B, 13C and 13D) can be any portion of the tire sidewall (12), preferably the sectors (13) being quadrants, halves, or the whole annular surface (11). The resulting patterns yield a decorative sidewall (12) having unique contrasting light and dark appearance.</p> |
