PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2012/066717
Kind Code:
A1
Abstract:
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 (16) are provided in a first region (R1) 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 (R1) and provided around each of the recesses (16) 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.
