  "textContent": "A pneumatic tire includes, on a surface of a side rubber provided on sidewall portions, a two-dimensional code in which a dot pattern is formed by two types of gray scale elements distinguishable from each other by irregularities on the surface. Dot holes are formed in the two-dimensional code, corresponding to dark elements of the gray scale elements. The side rubber is a diene rubber including butadiene rubber, and when A is a blended amount of the butadiene rubber relative to 100 parts by mass of the diene rubber contained in the side rubber and when B is a blended amount of carbon, a ratio A/B and a hole depth D (mm) from an opening of the dot hole to a hole bottom satisfies a relationship of 1.1≤(A/B)/D≤6.0.",
