  "textContent": "A surface of a sidewall portion of a pneumatic tire includes: a ridge pattern region provided with a plurality of ridges extending continuously in one direction at an interval, a smooth surface region composed of a smooth surface, and a two-dimensional code having a rectangular shape in which a dot pattern is formed of two kinds of gray scale elements that are formed distinguishable from each other by unevenness of a surface. The two-dimensional code is provided in the smooth surface region, and a shortest distance Lmin at a position where a distance from the ridge pattern region to the two-dimensional code is the shortest distance Lmin among four sides of the rectangular shape of the two-dimensional code is from 3 to 25% of a length W of one side, of the two-dimensional code, the one side having the position where the distance of the two-dimensional code is the shortest distance Lmin.",
