ABSTRACT:
The noise caused by vehicle tires rolling on a road surface is reduced by enclosing in the space confined by the tire and the wheel rim a noise or sound absorbing or insulating material which may assume various shapes. This noise absorbing or insulating material may be connected to the inner tire surface or to the rim surface facing into the tire. Thus, the material is not externally visible once the tire has been mounted on the wheel rim.
