A center clamping mechanism for a wheel assembly service machine such as a tire changer machine includes a back cone centering element projecting outwardly from a platen and configured to engage a center bore of the wheel rim hub mount pad from an inner side of the hub mount pad. The centering element may include a compliant element configured to at least partially support the weight of the wheel rim and tire when being clamped. A pivot arm defines a contact surface for the inner side of the wheel rim hub mount pad, and when the tire is rotated by an operator with the inner side in contact with the contact surface, an anti-rotate pin carried on the pivot arm may be adjusted in radial position relative to the drive axis to accommodate different lug holes at varying lug bolt circle diameters.
