Can someone please lend some advise on cross model (Sedan/Coupe) & cross model year OEM wheel/tire compatibility?

I recently purchased a 2006 G35 sedan (standard model w/ auto trans) and I'd like to turn my existing set of stock wheels into a set of winter wheels w/ snow tires and purchase another set of used OEM wheels/tires via the forum classifieds when the right set appears.

I've searched the forums but I'm having some difficulty trying to determine what 17" & 18" OEM wheels will fit my car without me having to modify anything, and along the same lines, what tire sizes (same front/rear or opting for an offset if choosing coupe wheels) will work.

Any help you can provide would be appreciated!

Did you look on this thread?

What are you trying to do? All the G models have the same bolt pattern so they all theoretically fit. Your offset on the factory sedan is 40mm or 42mm. The lower the number is the further pushed out of the wheel well they get. Simply putting spacers on can help alot.
