摘要:
This pneumatic tire has a plurality of recesses 22 provided on the surface of each FIG. 21 of a first indication portion 20. The recesses 22 are provided so as to extend in the tire circumferential direction and are aligned side by side with each other in a direction crossing the extending direction. One end side and the other end side in the width direction of each recess 22 are formed by curved surfaces of which a center of curvature is disposed at the outside in the tire width direction. Therefore, gradation of brightness occurs on the curved surface on the each recess 22. The gradation on the each recess 22 changes depending on the viewing direction or the lighting direction. Therefore, each FIG. 21 in the first indication portion 20 looks three-dimensionally and can become more conspicuous than the other portions of a side wall 10.
