Hi,

I have a 2009 G37S with winter tires on the stock rim. (believe they are called the 10 spoke 19", wider in the rear)

I have 2 rear summer tires took off from these stock rim past summer and im planning to buy 1 new set of rim plus 2 new front summer tires.

I got a seller selling a set of 15 spoke 19", i believe they are from 2011-2013 model, but i think all 4 are the same size
if this is true this mean the front 2 rims will be wider than my current stock winter rim.

Question:
are this new set indeed the same size on all 4 rim?
will they fit my car?
would my plan work? i.e. wrap my old rear tire (stock size on 2009 S coupe) on these new set and buy new summer front tires for the front rim.

 

If they are 19" OEM Infiniti G wheels they will fit your car, if they happen to be from a convertible they will have more aggressive (less positive) offsets but they will still work ok. If they are (4) front wheels they will be 8.5" wide, your rear wheels are 9" wide. You can run 245/40/19 on 8.5 & 9" wheels without problems.

 

Hi, thanks for your valued input.

According to the seller. They are
"19 X 8.5 square set up off set 43 centre hub 66.1"

Does that mean it's the 4 front wheel situation? (Do you happen to know which model they were taken off from?)
I only know the non sport model is 18" and sport is 19". Not aware of here are 8.5x4 or 8.5x2 + 9.5x2 setup.

Thanks again

 

Post pictures of the wheels.

 

Yes, they're all 4 front wheels...since you have a sport you can run square but staggered is what you car is built for.

 

Sorry. I have only received 1 picture

 

Hi. Thanks for your input.

What maybe the difference in performance I may notice between W setups?

 

Your statement may be true for coupes. Barring Akebono brakes, all G37s can use the same wheels so you have to know that the sedan comes with 17" and 18" wheels. My sedan Sport came with 18" staggered. Non-sport sedans generally come with square 17s. I believe the AWD models come with square 18" but I didn't sleep at a Holiday Inn Express last night and may have that backwards. No idea what size wheels come on the convertible.

 

Handling would be the most noticeable...some oversteer maybe
