发明名称 Pneumatic tire
摘要 A side wall portion including, in a specific region in a tire radial direction, a decorative region including two or more decorative portions that are continuously disposed so as to be contiguous in a tire circumferential direction, the decorative portions including multiple convex ridges that are disposed on an outer surface so as to be adjacent in the tire circumferential direction. The ridges in the same decorative portion have a same ridge arrangement angle, and the ridge arrangement angle of the contiguous decorative portion differs therefrom not less than 20° and not more than 160°. In all regions in the tire circumferential direction, at least one side in the tire radial direction of the decorative portion overlaps with the contiguous decorative portion. A distance between a first imaginary boundary line and a second imaginary boundary line is less than 1 mm.

主权项 1. A pneumatic tire comprising a tread portion, a side wall portion, and a bead portion, wherein the side wall portion comprises, in a specific region in a tire radial direction, a decorative region including three or more decorative portions that are continuously disposed so as to be contiguous in a tire circumferential direction, the decorative portions including multiple convex ridges that are disposed on an outer surface so as to be adjacent in the tire circumferential direction and the decorative region includes not less than three types and not more than nine types of the decorative portions having different ridge arrangement angles; a ridge arrangement angle, which is an angle formed by the ridges and a line tangent to the decorative region at an edge of an inner side in the tire radial direction, is the same in the same decorative portion, and a ridge arrangement angle of the contiguous decorative portion differs therefrom not less than 20° and not more than 160°; in all regions in the tire circumferential direction, at least one side in the tire radial direction of the decorative portion overlaps with the contiguous decorative portion; a first imaginary boundary line joining end portions of the ridges of the decorative portion that are on a side adjacent to the contiguous decorative portion and a second imaginary boundary line joining end portions of the ridges of the contiguous decorative portion on a side adjacent to the first imaginary boundary line extend from an inner side edge to an outer side edge in the tire radial direction, and a distance between the first imaginary boundary line and the second imaginary boundary line is less than 1 mm; and the ridges of the decorative portion are separated from the ridges of the contiguous decorative portion.
