Hello
I just purchased a 2011 g37s coupe. The car is amazing and love the engine sound! As the winter is coming, i am looking for a winter tire but as you know 19in wheels and tires and expensive. Is it possible to put in the 17 or 18 wheels instead of 19? Currently it is sitting on a 19inch

 

Welcome to the site!
The main concern is clearing your big Sport calipers, the 18" sedan wheels from the S models along w/ the XS sedan wheels will work. There's also base 18" Z wheels that will clear. Enkei makes some 18s that clear, 17" wheels that will clear are rare, volk te37s come to mind but they're high dollar.

 

Thank you!

 

One more questions,
ALLOY WHEEL, 18 X 8, 6 ROUND SPOKE, SILVER
These are from Zs. Would this rim fit on my g37s with 19 rims

 

Do you have a pic or a link for this wheel? They should fit but just to be sure.
Here's a couple links to Z wheels for reference

Hey so this is the link
18" like new, bright silver alloy wheels. Infiniti/Nissan 5 bolt.
I found these wheels but I am not sure if it will fit on my g37s with 19 inch wheel

 

Those are the 2007+ sedan wheels, they won't clear the big brakes

 

Haha. I guess just getting the tires and swapping them after winter would be the best option lol
