The surface of a tire side surface of a pneumatic tire includes a two-dimensional code in which a dot pattern is formed by two types of gray scale elements formed identifiable from each other by recesses and protrusions of the surface, or a predetermined two-dimensional code arrangement region. The surface of the tire side surface further includes at least two marks formed in a protruded shape or a recessed shape, and the two marks are disposed on an identical position in a first direction of a tire radial direction and a tire circumferential direction and disposed separated from each other at different positions in a second direction of the tire radial direction and the tire circumferential direction to sandwich an outer edge of the two-dimensional code or the predetermined two-dimensional code arrangement region from the opposite sides in at least one of the tire radial direction or the tire circumferential direction.
