Would you pay a professional to put air in your tires?

No. I would pay a professional, though, to inspect and repair my
steering or brakes.

As to a transponder, and its vitial importance to the system (and to my
TCAS when sharing the airspace with VFR aircraft) a transponder's proper
functioning has importance to everyone using the system. Your proper
tire inflation does not.
