Hey guys,

I can't get no response about 370z sport wheels on G37x under wheel/tire section...

maybe one of Sedan guys can help me out.

I'm trying to put 370z sport wheels :
19x9 +47 Front / 19x10 +30 Rear
245/40/19 Front / 275/35/19 Rear

Would this work on my X ? if not, what would be the proper tire size for the X ?

Your help is greatly appreciated!

 

so I came up with this tire rolling diameter calculation... Let me know if I'm on the right track.
I heard some of you said that not to throw off AWD system, rolling diameter should remain within 5%.

2011 G37XS
STOCK TIRE : 225/50/18
SIDEWALL : 4.4 IN
RADIUS : 13.4 IN
DIAMETER : 26.9 IN
CIRCUMFERENCE : 84.4 IN
REVS/MILE : 751.0

NEW TIRE (FRONT) : 245/40/19
SIDEWALL : 3.9 IN
RADIUS : 13.4 IN
DIAMETER : 26.7 IN
CIRCUMFERENCE : 83.9 IN
REVS/MILE : 755.0
* THIS PUTS WITHIN 0.5% FASTER FROM STOCK *

NEW TIRE (REAR) : 275/35/19
SIDEWALL : 3.8 IN
RADIUS : 13.3 IN
DIAMETER : 26.6 IN
CIRCUMFERENCE : 83.5 IN
REVS/MILE : 759.0
* THIS PUTS WITHIN 1% FASTER FROM STOCK *

My question is... both front and rear tires will stay within 1% from stock but will they be okay for X system ?

 

If you are within 1%, you'll be just fine and not do any damage to your AWD.

 

I thought having different sizes would be really bad for an AWD car 0.0
My friend used to always keep same tires and if one blew up he would replace all of them, in his Evo

 

Hey you can run the 370z wheels without any problems. My friend has had them on his G37x for about 10k miles and he has no problems with the AWD, so you should be fine

 

Gangsta, do you have a pic of your buddy's X with Z wheels?

 

mehhh, me and 4 of my boys ran them on our Xs 2 yrs ago> old news.

 

On a X:
Just put the 370z wheels on my car... - G35Driver

non-X:
Just got 370z wheels - G35Driver

Oh, and if you want my opinion, you can make them fit with lots of negative camber, lowering and trimming in the rear, but I really think the rear is too aggressive and the front not nearly aggressive enough (although you can add spacers to the front).
