A pneumatic tire comprising: a side portion including a sidewall and a bead portion, the sidewall being continuous along a tire radial direction inner edge of a tread side portion and extending inward in the tire radial direction, and the bead portion being continuous along a tire radial direction inner edge of the sidewall; and an annular decoration printing portion comprising ink; the decoration printing portion including an annular design portion comprising ink and an annular gradation portion comprising ink and being provided at least on the tire radial direction outer side of the design portion, and the gradation portion incrementally decreasing in value outward in the tire radial direction, with a value of 100% being a pure color and a value of 0% being pure black in an HSV color space, characterised in that: at least a portion of the annular decoration printing portion is provided on an outer surface of the side portion further toward a tire radial direction outer side than a tire maximum width position; in the gradation portion, the ink decreases in thickness outward in the tire radial direction; wherein the decoration printing portion includes an additional gradation portion comprising ink on a tire radial direction inner side of the design portion, and a width of the additional gradation portion in the tire radial direction being at least 3 mm and at most 10 mm, in the additional gradation portion, the ink decreasing in thickness inward in the tire radial direction, and the additional gradation portion incrementally decreasing in value in the HSV color space inward in the tire radial direction. a side portion including a sidewall and a bead portion, the sidewall being continuous along a tire radial direction inner edge of a tread side portion and extending inward in the tire radial direction, and the bead portion being continuous along a tire radial direction inner edge of the sidewall; and an annular decoration printing portion comprising ink; the decoration printing portion including an annular design portion comprising ink and an annular gradation portion comprising ink and being provided at least on the tire radial direction outer side of the design portion, and the gradation portion incrementally decreasing in value outward in the tire radial direction, with a value of 100% being a pure color and a value of 0% being pure black in an HSV color space, characterised in that: at least a portion of the annular decoration printing portion is provided on an outer surface of the side portion further toward a tire radial direction outer side than a tire maximum width position; in the gradation portion, the ink decreases in thickness outward in the tire radial direction; wherein the decoration printing portion includes an additional gradation portion comprising ink on a tire radial direction inner side of the design portion, and a width of the additional gradation portion in the tire radial direction being at least 3 mm and at most 10 mm, in the additional gradation portion, the ink decreasing in thickness inward in the tire radial direction, and the additional gradation portion incrementally decreasing in value in the HSV color space inward in the tire radial direction. at least a portion of the annular decoration printing portion is provided on an outer surface of the side portion further toward a tire radial direction outer side than a tire maximum width position; in the gradation portion, the ink decreases in thickness outward in the tire radial direction; wherein the decoration printing portion includes an additional gradation portion comprising ink on a tire radial direction inner side of the design portion, and a width of the additional gradation portion in the tire radial direction being at least 3 mm and at most 10 mm, in the additional gradation portion, the ink decreasing in thickness inward in the tire radial direction, and the additional gradation portion incrementally decreasing in value in the HSV color space inward in the tire radial direction.
