The present turbine fan rim, turbine fan airless tire and turbine fan hubcap designs are configured to remove air from under the underside of a moving vehicle when rotated in a particular direction, typically in a forward direction. This air movement can create a vacuum below the vehicle, which can create a down force on the vehicle increasing traction between the vehicle's tires and the road surface and lowering the vehicle's center of gravity. This downward force and partial vacuum can thus increase as the rotational velocity of the tires increases, providing greater traction at higher speeds. An additional benefit to these wheel, airless tire, and hubcap designs is the cooling effect that would be created by the flowing air on brake parts that are located near wheels of nearly all vehicles.
