1. A pneumatic tire, comprising two spaced apart bead portions, a tread portion, a pair of sidewalls extending radially inward from axially outer edges of the tread portion to join the respective bead portions, the axially outer edges of the tread portion defining a tread width, a carcass, an innerliner covering the carcass and defining a tire cavity, and a first foam strip material layer of an open cell noise damping foam strip material, a second foam strip material layer of the open cell noise damping foam strip material, and optionally additional foam strip material layers of the open cell noise damping foam strip material, wherein the first foam strip material layer has a single male dove tail connector element on one side of the layer and a single female dove tail connector element on the opposite side of the layer, wherein the second foam strip material layer has a single male dove tail connector element on one side of the layer and a single female dove tail connector element on the opposite side of the layer, wherein any optional additional foam strip material layers have a single male dove tail connector element on one side of the layer and a single female dove tail connector element on the opposite side of the layer, wherein all of the layers of foam strip material in the tire are of the same size and geometry, wherein the male dove tail connector element of the first foam strip material layer is glued to the innerliner, wherein the first foam strip material layer is situated within the tire cavity in an area radially below the tread portion, wherein there is a slot between the first foam strip material layer and the innerliner, wherein the second foam strip material layer is mechanically interconnected by its male dove tail connector element to the female dove tail connector element of the first foam strip material layer, wherein any additional foam strip material layers are attached to the second foam strip material layer through mechanical dove tail connections, wherein each foam strip material layer of the open cell noise damping foam strip material has an axial width from 20% to 80% of the tread width and a radial thickness from 5% to 20% of the tread width, and wherein the sum of the volume of the first foam strip material layer, the second foam strip material layer, and any additional foam strip material layers represents from 8% to 40% of the volume of the tire cavity.
