A pneumatic tire (1) includes a a tread (2); side walls (3), beads (4), a carcass (6), a belt layer (7), and an inner-liner layer (9), and a sealant layer (10); the inner-side surface of the inner-liner layer (9) to which the sealant layer (10) is adhered has a profile that satisfies L1 < L2 < L3, L1 < 5 mm, L2 < 9.5 mm, and L3 < 11 mm, where L1, L2 and L3 represent heights in a radial direction measured from a base height point to the inner-side surface of the inner-liner layer (9) at positions located in an axially inward direction from an axial outer edge (7e) of the belt layer (7) by 5%, 10% and 15% of a maximum width (Wa) of the belt layer (7), and the base height point is a point on an axial-direction line that passes through the intersection where a radial-direction line passing through the axial outer edge (7e) of the belt layer (7) intersects the inner-side surface of the inner-liner layer (9); and a foamed body is laminated on the tire radially inner side surface (10a) of the sealant layer (10)
