  • Publication number: 20120055603
    Abstract: A pneumatic tire including a decorative portion having at least one ridge group that extends band-like in the tire circumferential direction on the outer surface of the side wall. Each of the ridge groups is formed from a bundle of ridges. An entirety of each of the ridge groups is formed into a wave-like shape that extends in the tire circumferential direction, and each of the ridge groups is arranged so as to mutually cross at a plurality of locations in the tire circumferential direction. Therefore, the decorative portion is noticeable, and the decoratability of the tire can be enhanced.

  • Publication number: 20110253278
    Abstract: 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.
