    • A pneumatic tire has no spew or no spew trace on a sidewall surface of the pneumatic tire and reduces air resistance. The tire includes a plurality of dimple-like recesses and a plurality of linear valley portions. The dimple-like recesses are provides in a first region including a tire maximum width position of the sidewall surface of the tire. The linear valley portions which are formed by serration of the sidewall surface, extend linearly in one direction in the first region and provided around each of the recesses so as to enclose each of the recesses. When a size of an occupied area of each of the recesses on the sidewall surface is represented by an equivalent diameter of a circle, an interval distance between the linear valley portions is smaller than the equivalent diameter.
    • 充气轮胎在充气轮胎的侧壁表面上没有喷射或没有喷射痕迹并且降低空气阻力。 轮胎包括多个凹坑状凹部和多个线状谷​​部。 凹坑状凹部提供在包括轮胎侧壁表面的轮胎最大宽度位置的第一区域中。 由侧壁表面的锯齿形成的直线谷部分在第一区域中沿一个方向线性地延伸并设置在每个凹部周围,以包围每个凹部。 当侧壁面上的每个凹部的占用面积的大小由圆的等效直径表示时,直线谷部之间的间隔距离小于当量直径。
