Abstract
The invention relates to an elastic vehicle tire (1) comprising a tire cavity. Said cavity is enclosed by a running strip (2) supporting the tread surface (3) and a side wall (4, 4.1) formed on each side of the running strip (2). A noise dampening insert (9) or a noise dampening insert arrangement disposed therein is provided in the tire cavity. A ventilation layer (13) having a structure permeable to air at least in the transverse and/or longitudinal direction of the running strip (3) is disposed between the noise dampening insert (9) or noise dampening insert arrangement and connected to the inner side (10) of the running strip (2) supporting the running surface (3). Said layer is suitable for passing an air flow at least partially in contact with the inner wall (10) of the running strip (2).
