1. A pneumatic tire comprising:
a sidewall portion having an outer surface provided with a decorative portion extending in the circumferential direction of the tire in an arc shape, wherein
the decorative portion comprises a first pattern area having a first surface design, and a plurality of second pattern areas having a second surface design different from the first surface design of the first pattern area, and
the first pattern area and the second pattern areas are partitioned by first boundaries extending parallel to a reference center line which extends in a radial direction of the tire through the center in the tire circumferential direction of the decorative portion when viewed perpendicularly and second boundaries extending orthogonally to the reference center line, wherein
when a number N is an integer of 3 or more and the decorative portion is divided into the number N of decorative zones by parallel straight lines which are perpendicular to the reference center line so that, at the position of the reference center line, the decorative portion is divided into the number N equal parts by the parallel straight lines,
percentages of areas occupied by said first pattern area in the respective decorative zones gradually increase from the radially innermost one to the radially outermost one of the number N of the decorative zones at the position of the reference center line.
