A method and system for a vehicle wheel are provided. The vehicle wheel includes a circular hub, a concentric rim circumscribing the hub, a plurality of circumferentially spaced-apart spokes extending radially between the hub and rim, each pair of adjacent spokes having an opening therebetween extending at least partially between the rim and hub, and a shutter assembly coupled to the wheel, the shutter assembly including at least one shutter coupled to a closure mechanism that includes a biasing mechanism configured to bias the at least one shutter toward a first relatively open position when the wheel is rotated at less than a predetermined speed. |
