A vehicle wheel changing aid for mounting and removing a vehicle wheel to and from a jacked position on the wheel axle of a vehicle. The device includes a rocker base having an operator end, a wheel receiving end, and a bottom facing pivot surface adapted to contact the ground as the rocker base is pivoted. A plurality of spaced apart rollers are mounted on the base near the wheel receiving end and allow rotation of a vehicle wheel in order to accurately align the wheel lug openings with the lugs on the axle hub during the changing procedure. A knee/foot bearing pad is positioned towards the operator end of the base and permits the vehicle wheel to be raised or lowered from the axle hub of the vehicle by applying the operator's knee/foot to rock the base of the device. The knee/foot bearing pad may be extendably mounted to the base to increase the mechanical advantage in raising and lowering the wheel and provide additional operator clearance for safety purposes. A pair of wheels is mounted to the base on an axis transverse to the rollers to permit dollying the vehicle wheel to and away from the axle hub.
