Abstract
A vehicle wheel includes a wheel rim having an outside carrying airborne noise-absorbing fiber material in the form of a carrier layer having fibers projecting radially outwardly of an outside of the rim. The rim has an interior tire bead contact area which is spaced from an edge of the fiber material a distance at least equal to the length of the fibers to prevent the latter from entering the tire bead contact area. The fiber material is also preferably located at a depressed area between rim beads and the length of the fibers is preferably between 5 mm and 40 mm.
