PNEUMATIC TIRE

In a first aspect, the present invention is directed to 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, and at least one noise dampening strip which is partially covering and attached to the sealant material on a radially inner side and along a circumferential direction of the sealant material layer. The sealant material layer has at least one plateau region supporting the noise dampening element and one or more bottom regions provided laterally beside the plateau region, and wherein the plateau region extends out of the bottom regions in a radially inner direction.In a second aspect, the present invention is directed to 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, and at least one noise dampening element which is partially covering and attached to the sealant material on a radially inner side of the sealant material layer. The sealant material layer has at least one plateau region supporting the noise dampening element and one or more bottom regions provided laterally beside the plateau region, wherein the plateau region extends out of the bottom regions in a radially inner direction. Moreover, the sealant material layer comprises i) one or more sealant material strips spirally wound about an axis of the tire and along the inner surface of the tire, or ii) axially adjacent sealant material strips extending circumferentially about an axis of the tire and along the inner surface of the tire, wherein said strips have a larger thickness in the plateau region than in the bottom regions.
