Apparatuses and methods for adapting a tire machine to accept small wheel assemblies. A first embodiment includes a cross shaped guide with clamp adapters that glide in unison to engage and disengage the small wheel assembly via a rim hooking structure that extends the reach of the OEM tire clamps. Each clamp adapter is set over the OEM tire clamps and is engaged or closed via an engagement clip and opened or disengaged via a disengagement clip disposed on each clamp adapter. Another embodiment includes individual clamp adapters that are slid over the OEM tire clamps to extend the reach of the OEM tire clamps. A stop hook is disposed on the clamp adapters to engage a clamp hook on the OEM tire clamp when the tire machine is activated which engages a raised adapter hook on each clamp adapter to the small wheel assembly rim edge.
