Abstract:
The invention relates to a pneumatic vehicle tire (L) having at least one acoustic element (8), wherein the tire (L), fitted on a wheel rim (16), encloses with the rim (16) a space inside the tire (17), wherein the acoustic element (8) comprising a body (12) and a layer (13) is arranged on an inner tire surface (10) involved in delimiting the space inside the tire (17), wherein the body (12) is arranged on the inner tire surface (10) and wherein the layer (13) is arranged on a surface region of the body (12) that is facing the space inside the tire (17). The object is to provide a tire which has improved acoustic properties with less use of porous noise-reducing material and the acoustic element of which is more resistant to pressure changes. This is achieved in that the layer (13) is arranged on at least 15% of that surface of the body (12) which faces toward the space inside the tire (17), in that the layer (13) has a first surface region (9) which is arranged at a distance from the inner tire surface (10), in that the first surface region (9) is connectable pneumatically to a surface region (11) lying opposite it and in that the layer (13) has a sound reflectance of at least 80% for a sound wave striking the first surface region (9). The invention also relates to a wheel rim (16) and to a wheel having such an acoustic element (8).
