All Infiniti G37s and Q50/60 use the same center cap size, also the maxima & 370z also share the same size (and I believe the Altima does as well).

 

Thanks blnewt. I went back out and measured again more closely and yeah they're as close to 2.125 inches as I can get it.

 

I have a G37x. How can I run 19x9.5 +40 front and 19x10.5 +23 rear to make the car think its running a square setup as its AWD?

 

Here's the best combos for common 19 setups that will work on AWD Gs, last number is diameter variance, need to be under 1%.
19s
225/45 & 255/40 0.06%
235/40 & 265/35 -0.37%
235/40 & 275/35 0.67%
245/40 & 275/35 -0.52%
245/40 & 285/35 0.51%

That 235/265 combo would be your best bet for fit at the fender, both would be considered a stretch mount though. The 245/275 would be a better mount but may have contact at the back fender if you keep camber at spec.

Member Ryne ran the same tire size on staggered wheels without any issues, you could go that route too.
Check his build thread for more info & pics, you'll have to scroll through it as he ran several different tire/wheel sets.

Hello,

If I put 245/40 on the front and 275/35 on the back for my 2008 g37 sport coupe will it interfere with the traction control system?

 

I assume 19" wheels, that won't be a problem at all.

 

Nope. Only thing that will bother traction control is using the curbs at the race track. These cars like that tire size.

 

Hello all,

I've looked through quite a bit of info so far, but tend to get mixed general insight.

I have a 2013 G37S sedan with the 18"x7.5" front and 18"x8.5" rear duckfeet wheels. I'm curious if stock 8.5" can be installed up front to run a squared setup. I intend to buy Nitto NT555 G2 255/45ZR18 all the way around. Any other recommendations are welcome.

Thanks

 

Yes, you can run 4 of the wider rear wheels all around, and the 255/45 is a good size there. And nice to be able to do a true rotation even though those NT555s are directionals (at least the first generation NT555s were).

 

I'm completely fine with only rotating front to rear instead of no rotation at all. I'm assuming that the 2mm difference in offset wouldn't be visibly noticeable?

Thanks for the quick response. Time to look high and low for reasonably priced set of rear wheels.

 

2 mm is not even a tenth of an inch. You'll notice that?

 

No, definitely not. It was late(or early, depending on how you look at it) and I must have been immediately thinking centimeters.🤔

 

I and have read many pages but I am not quite understanding which size tire I can fit WITHOUT adding spacers or making any modifications to suspension, etc. Basically I just want to be able to mount a slightly larger tire on the fronts and rear while keeping ride quality comfortable and good.

I drive a 2007 G35 Sedan Sport 6MT RWD that currently has mounted the 2008 Coupe G37 rims (Currently fronts have 225/45/19R and rears have 245/40/19R).

What is the biggest size tire I can run without having to run spacers or change anything with suspension? I'd like to leave my 2007 G35 Sedan Sport the same just run a slightly larger tire then I am currently running. Please let me know, I have really tried to understand but I am very confused. I would appreciate your help so much! I plan to order all season either the G-Force Comp-2 A/S or Pilot Sport A/S 3+. I need tires really bad and haven't driven in months because of this so your help is a huge thank you!

 

I just want to increase slightly because of the cost of the tires, what would be the next size up from the front- 225/45/19 and rear- 245/40/19 that I currently have on my 07 G35 Sedan Sport with G37 rims? I looked into the 245/40/19 and 275/35/19 pricing and it is roughly $80 more which is quite a bit but if it will give my ride a better look & comfortable I'll front that cash. But please let me know about a good size in between what I have now and the size I just posted in the sentence before. Thanks!
