Abstract: An inflation system for wheel assemblies having tires and rims includes a primary inflator tool, a nest, and a secondary inflator tool. The primary and secondary inflator tools are configured to advance toward the wheel assemblies, engage the wheel assemblies, inflate the tires of the wheel assemblies, and retract from the wheel assemblies after inflating the tires. The nest is configured to transition between first and second positions. In the first position the nest is aligned with the primary inflator tool. In the second position the nest is offset from the primary inflator tool. The secondary inflator tool is configured to be positioned on the nesting fixture in an idle position. The secondary inflator tool is configured to be detachably coupled to the primary inflator tool in an operational position.
