Rears will be about an inch taller and over 3% different than your front tire diameter, they'll fit but I'd stick to the same sidewall height as your fronts w/ the 35 series in back.

 

Thank you if I do go with the 40 in the back would it damage anything or effect the ride

 

As a general rule w/ RWDs you want to be within 3% of OEM tire diameters.
As far as damage goes, I wouldn't try it

 

I'm sorry for the stupid question but this is my first set, what other tire options do I have other the 245/275 were I could maybe run 245/45 and 275/40

 

Tell me if this will work on my 08 coupe please
Enkei Kojin
18x8.5+35 front with 245x45-18
18x9.5+30 rear with 275x40-18
would like to stay at stock ride height
Thanks!

 

I have a 2010 G37x Coupe and I'm looking to buy 20'' Rohana RC10's. Right now my car is at stock height but within the next year, I will drop it on coils.

I want a square setup and my car to sit flush with no rubbing and no fender adjustments. Any suggestions?

Thanks in advance!

 

Ive got a 2008 G37s coupe and ive just bought a set of Varrstoen ES2's for practically nothing and im in the process of trying to get them to fit. From all my research it doesnt seem like it will take too much to fit. The sizes are 19x9.5 +30 with a 235-35-19 and 19x10.5 +30 with a 285-35-19. Im probably going to lower the car on a set of Tein S-techs as well. Problem is that I cant get the fronts to clear the Akebono's. I think im gonna need a set of either 15 or 20mm spacers with extended lugs. Has anyone run into trying to fit these before??

 

You won't have any variance in diameter front to back which is good, just the
overall diameters are an inch taller than stock, there's been guys that have gone up or down in overall diameter without issues, but as a general rule I'd stick closer to stock diameters if it were me.

 

Replied in your other thread

 

Try this template on those wheels for a better idea of just how much spacer you'll need

Thank you for the answers, I'm going to go with 245/40 and 275/35 like you said

 

Really like'n the idea of going with the 370Z wheels on my "370GT"....the
19x9 +47/ 19x10 +30 ....just wondering for my G37xS what would be an ideal set-up/tire size to run on? and not mess up the AWD system?
I currently have the 18' sports with H&R 20mm/25mm spacers and just went with the Swift springs....Thanks guys for the info!!!

 

G looks nice w/ your new drop. As far as the Z wheels, they'll fit but will poke in back a bit w/ your mild drop, also having to run stretched in the back will make the actual running diameter harder to predict. You really need almost zero variance from OEM diamters front to back w/ an AWD so I wouldn't recommend going w/ that setup.

 

So If I did want to run this set-up what tires/sizes would I be able to run on my G37xS or it's completely out of the question to run these on an AWD
and if so... I'm better off looking at a 19x8.5 set with like 245/40/19's

 

The main obstacle is the stretched rear tire, having the tire stretched will change the diameter compared to a standard mount and determining the adjusted diameter is hard to do without actually buying the tires and
running them. A variance over 1% from your front tires will most likely cause issues w/ your AWD system. Running a square setup is easier, and you can see a few setups over in this thread that are still quite aggressive
