If you're truely going to "Restore" your Charger (you did say Restore, right?) I would consider 15x7 Rallyes with maybe a 245/60/15 on all four corners.

I think the Firestone "Indy" series tires in 245/60/15 look very close to the G60 Belted tires of the day.

That's the biggest wheel combo I can think might have come on your '73 from the factory.

Now if you're intention is to "Restiy" or perform a "Restification" on your car, that's a whole different story, and perhaps even a better description of your true intentions as you mentioned the possibility of entertaining a 16" wheel on your charger.

Have you considered aftermarket 15" or even 16" chromed rallyes or magnum 500's?

4.5" back spacing is the way to go.

Good luck and please post some pics of your car once the Restoration is completed.
