Default Max wheel and tire size for a Stock 370z?

I have a Base 370z and i'm trying to put some new wheels on, that i got for a steal, they were previously on a G35. The front wheels are going to run 265/35/20 the wheels are 10.5 inch thick.
The rear wheels will be running: 305/35/20, the wheels for the rear are 11 inches thick.
Ive looked everywhere for someone running these. I wont be too torn up if they don't, ill just resell them and get another set of wheels.
For what its worth, the wheels are AG M350, I was not planning on rolling the fenders, but if need be I will do. Any feed back is appreciated
Thanks!

The front size you want to run are a bit too tall and the rears are WAY too tall.

Stock Base 18 Reference:
225/50-18 26.86"
245/45-18 26.68"

Your suggested sizes:
265/35-20 27.30" +0.44"
305/35-20 28.41" +1.73" (had to emphasize that in RED)

20" Sizes that would be acceptable (given width of wheels):
Front: 285/30-20 26.73" or 295/30-20 26.97"
Rear: 295/30-20 26.97" OR 305/30-20 27.2" (a tad tall but it works on Z34)

That all said, I have a friend who runs a set of GTR Track 20s on his Z34N with 275/30 & 305/30 with no issues and close to perfect fit with the spot-on correct offset; but the GTR Tracks are 9.5/10.5. I'd GUESS that the 285/305 setup would work IF THE OFFSETS ARE RIGHT (the most important measurement which you didn't mention.)

FYI, a pretty hot set up on lowered Z34: 19x10 +15 (+/-5mm) F and 19x11 +15 (+/-5mm) with 275/35 and 305/30-19 - Tire diameters are both a little less than stock Nismo but works really well. Only consideration with going up this wide is that unless you're racing, the tires never really reach optimum op temp (especially on Z34 which is lighter than Z33). But most people running these sizes don't really care cuz it LOOKS bishin'!
