Pneumatic tire

A pneumatic tire comprising a tread portion, two bead portions, two sidewalls extending between the tread portion and the respective bead portions, an inner surface defining a tire cavity, a sealant material layer covering the inner surface radially below the tread portion within the tire cavity, a noise dampening strip which covers and is attached to the sealant material along a circumferential direction and on a radially inner side of the sealant material layer, wherein the sealant material layer has three bottom regions and two plateau regions, wherein the plateau regions provide support for the noise dampening strip, wherein the two plateau regions are separated from each other by a bottom region, wherein only the plateau regions of the sealant layer are in direct contact with the noise dampening strip, wherein the plateau regions extends only radially below the noise dampening strip and not axially beside the noise dampening strip, wherein the thickness of the plateau regions is 20% to 90% thicker than the thickness of the bottom regions, wherein the plateau regions have an essentially constant thickness, and wherein the sealant material layer has shoulder regions extending between the plateau regions and the bottom regions, and wherein the shoulder regions axially extend over less than 10% of the axial width of the sealant material layer.
