A pneumatic tire , comprising: a tread ; a pair of side walls extending from axial edges (Te) of the tread in a radially inward direction, respectively; a pair of beads positioned on a radially inner side of the sidewalls and having a pair of bead cores , respectively; a carcass extending from the tread through the sidewalls to the bead cores of the beads ; a belt layer positioned on a radially outer side of the carcass and on an inner side of the tread ; an inner-liner layer comprising air-impermeable rubber and positioned on a radially inner side of the carcass ; and a sealant layer adhered to a radially inner-side surface of the inner-liner layer in a tread section and having a tire width which is greater than a tire width (Wa) of the belt layer in an axial direction, characterized in that the inner-side surface of the inner-liner layer to which the sealant layer 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 at positions located in an axially inward direction from an axial outer edge of the belt layer by 5%, 10% and 15% of a maximum width (Wa) of the belt layer in a meridian cross section including a rotation axis of a tire when the tire is mounted on a normal rim and is filled to have a normal inflation pressure with no load applied, 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 of the belt layer intersects the inner-side surface of the inner-liner layer , the air-impermeable rubber is one of butyl rubber and halogenated butyl rubber; and in that a foamed body is laminated on the tire radially inner side surface of the sealant layer . a tread ; a pair of side walls extending from axial edges (Te) of the tread in a radially inward direction, respectively; a pair of beads positioned on a radially inner side of the sidewalls and having a pair of bead cores , respectively; a carcass extending from the tread through the sidewalls to the bead cores of the beads ; a belt layer positioned on a radially outer side of the carcass and on an inner side of the tread ; an inner-liner layer comprising air-impermeable rubber and positioned on a radially inner side of the carcass ; and a sealant layer adhered to a radially inner-side surface of the inner-liner layer in a tread section and having a tire width which is greater than a tire width (Wa) of the belt layer in an axial direction, characterized in that the inner-side surface of the inner-liner layer to which the sealant layer 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 at positions located in an axially inward direction from an axial outer edge of the belt layer by 5%, 10% and 15% of a maximum width (Wa) of the belt layer in a meridian cross section including a rotation axis of a tire when the tire is mounted on a normal rim and is filled to have a normal inflation pressure with no load applied, 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 of the belt layer intersects the inner-side surface of the inner-liner layer , the air-impermeable rubber is one of butyl rubber and halogenated butyl rubber; and in that a foamed body is laminated on the tire radially inner side surface of the sealant layer . <EOS>
