Pneumatic tire

A pneumatic tire comprising:

• a pair of sidewall portions extending in a tire circumferential direction, the sidewall portions being provided to interpose an annular tread portion between the sidewall portions in a tire lateral direction,
• each of the sidewall portions including, on at least one surface of the sidewall portion, a ridge pattern region provided with a plurality of ridges continuously extending in one direction and provided at intervals, a non-ridge pattern region including a smooth surface and not provided with the ridges, and a two-dimensional code including a dot pattern formed from two types of gray scale elements distinguishably formed using surface irregularities, and
• the two-dimensional code being engraved with all of a region of the two-dimensional code overlapping the ridge pattern region or with the region of the two-dimensional code overlapping the ridge pattern region and the non-ridge pattern region, wherein
• the two-dimensional code includes dot holes forming the dot pattern, and some of the dot holes are formed overlapping the ridges;
• wherein
• as compared to a valley floor of a valley portion between the ridges, a hole bottom of each of the dot holes is positioned on a recess side with respect to the surface of the sidewall portion, and
• a hole depth d of the hole bottom is greater than a valley depth ds of the valley floor, and the hole depth d—valley depth ds is equal to or greater than 0.4 mm.
