Ok guys, I appreciate your input so far. Here is what I have decided to get for the Charger:

Rear:
Wheel Vintiques 54 series Magnum 500
15x8" rim size with a 4.5" backspacing, no offset
Cooper Cobra GT, P275/60R15

Front:
Wheel Vintiques 54 series Magnum 500
15x7" rim size with a 4.25" backspace, +6mm offset
Cooper Cobra GT, P235/60R15

These all have a 5x4.5" bolt circle which I believe is correct for the 8 3/4" axle. Can you guys check this over and make sure this looks right? I would measure some of these things myself but I don't have easy access to the car right at the moment.

Once I get the warm and fuzzy from some people here that are more knowledgeable, I might go ahead and order these babies!

Thanks in advance!
