A high-accuracy wheel spacer is used in an off-vehicle wheel servicing machine. The servicing machine includes an elongated mounting shaft operatively connected to a drive motor and extending outwardly from a motor housing. A face plate is fixed to the mounting shaft proximate the motor housing and cooperates with a clamping assembly to sandwich and dynamically center the vehicle wheel on the shaft. The wheel spacer includes a base having first and second opposing major surfaces. A plurality of outwardly-projecting spacer pins depend from the first major surface of the base, and are adapted for engaging a limited surface area of the face plate.
