Pneumatic tire

A pneumatic tire, comprising:

• a side rubber provided on each of sidewall portions of the pneumatic tire and covering a carcass ply of the pneumatic tire from an outer side of the tire;
• and
• a two-dimensional code provided on a surface of the side rubber, the two-dimensional code having a configuration in which a dot pattern is formed by two types of gray scale elements including a light element and a dark element distinguishable from each other by irregularities on the surface and in which dot holes are engraved using light, corresponding to the dark element of the gray scale elements,
• the side rubber being a diene rubber comprising 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 of the blended amount A to the blended amount B and a hole depth D (mm) from an opening of the dot holes to a hole bottom of the dot holes satisfying a relationship of 1.1≤(A/B)/D≤6.0, wherein
• a 300% tensile modulus of the side rubber is from 5.0 to 9.0 MPa,
• the blended amount A is in a range of from greater than 53 parts by mass to less than 68 parts by mass,
• a hole wall surface of each dot hole is provided such that a hole cross-section decreases as approaching from the opening to the hole bottom,
• a hole wall angle at a cut section of each dot hole obtained by cutting the dot hole by a plane comprising a hole center axis in a depth direction of the dot hole is from 10 to 50 degrees, with respect to the depth direction of the dot hole,
• a thickness of the side rubber on a first side in a tire radial direction is greater than that on a second side, the second side being a side opposite to the first side, in a range in which the two-dimensional code is provided, and
• the cut section is a cut section along the tire radial direction, and of the hole wall angles of the dot hole at the cut section, a hole wall angle θ1 on the first side in the tire radial direction is smaller than a hole wall angle θ2 on the second side in the tire radial direction.
