In a first aspect of the invention, a pneumatic tire (1) is provided, the pneumatic tire comprising two spaced apart beads (4), a tread portion (10), a pair of sidewalls (2) extending radially inward from axially outer edges of the tread portion to join the respective beads (4), the axially outer edges of the tread portion defining a tread width, a carcass (9), an innerliner (13) covering the carcass and enclosing a tire cavity when mounted on a rim, and multiple layers (30) of open cell, noise damping foam strip material attached on top of each other to the innerliner (13) within the tire cavity in an area radially below the tread portion (10), wherein each layer (30) 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 said multiple layers fill together from 8% to 40% of the volume of the tire cavity. Furthermore, in a second aspect, the present invention is directed to a method of manufacturing a noise dampened tire.
