I have a 2010 G37X Coupe and Im looking to replace my wheels. If i go with the wider wheels in the back, will it mess up my AWD system?

You can run staggered wheels, but use a tire calculator to make sure the overall diameters of the front and back are within 1% of each other.

Pick a set of tires from the following combos, then find wheels that will work with them
18s
235/45 & 265/40 (0.07%)
245/45 & 275/40 -0.07%
255/45 & 285/40 -0.22%

19s
235/40 & 265/35 -0.37%
235/40 & 275/35 0.67%
245/40 & 275/35 -0.52%
245/40 & 28535 0.51%

20s
235/35 & 275/30 0.07%
245/35 & 285/30 -0.07%

This calculator should be used when trying new setups~

Keep in mind the variances with a minus sign have smaller rear diameters, this isn't as good since the rears wear faster, this will cause the variance to increase over time. Not a big deal when you're starting at zero or close, but if you're already almost at 1% variance this needs to be considered. None of the above combos should have enough rear wear to be a issue but

Depending on how much wider you're going, you can run a square set of tires to keep your mind at ease...won't be able to do a full tire rotation but if you stagger you wouldn't be doing that anyway.

Staggered setups ok for AWD

19"
235/40R19 & 275/35R19
245/40R19 & 275/35R19
245/40R19 & 285/35R19
20"
235/35R20 & 275/30R20*
245/35R20 & 275/30R20
245/35R20 & 285/30R20

* - the best of those 6. Puts the rears at 0.07% larger circumference than the front

Man, I wish I had this type of web support and knowledge when I first got into cars 15-20 years ago.

I can email an Excel worksheet to do this to anyone who wants it.

what width of wheel/rim to run all four 275? 9"?

9.5" width is a better mount for a 275.
