Abstract
A wheel assembly for a vehicle includes a rim having a noise suppression device. The rim includes an outer radial surface that is concentrically disposed about a central axis. A tire is mounted to the rim to define a tire cavity between the outer radial surface of the rim and an interior surface of the tire. The noise suppression device includes a device wall that defines at least one resonator chamber, and includes a plurality of apertures allowing fluid communication between the tire cavity and the resonator chamber, with each of the plurality of apertures defining an opening area between the range of 0.03 mm2 and 0.8 mm2.
