    摘要： A pneumatic tire has a plurality of recesses provided on the surface of each figures of a first indication portion. The recesses 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 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. The gradation on the each recess changes depending on the viewing direction or the lighting direction. Therefore, each figure in the first indication portion looks three-dimensionally and can become more conspicuous than the other portions of a side wall.

    摘要翻译： 充气轮胎具有设置在第一指示部的各图的表面上的多个凹部。 凹部设置成在轮胎周向延伸并且在与延伸方向交叉的方向上彼此并排地对准。 每个凹部的宽度方向的一端侧和另一端侧由轮廓宽度方向外侧的曲率中心的曲面形成。 因此，在每个凹部的曲面上发生亮度等级。 每个凹部上的灰度根据观察方向或照明方向而变化。 因此，第一指示部分中的每一个图像三维地看起来都可以比侧壁的其他部分更显眼。
