245/40/19 or 245/35/19 on 9,5" ET25 G35x sedan

So guys I think, I've found new wheels for summer! Setup is G35x 2008 sedan on BC coils and Hotchkis sways.
Now I'm in doubts what tires to run! Now I have 245/35/20 on 8 ET40
So no stretch on this one, and wheels are hollow into the car even with 10mm spacers.
A 9,5" ET25 looks to be semi aggresive on a sedan (especially for Russia) and will make a stretch on a 245 tire

But what tire to run? I've seen only 9,5" ET15 on 245/35/19 (BBS LM reps) LightsOut ride...

 

i would at least do the 245/40. that is the stock size that comes on the G37 Sport 19" rears, and they are a 9" wide rim. i think 35 would be stretching it. i would probably step it up to a 275 if you dont want alot of stretch.

 

The thing is without a stretch I wouldn't fit 9,5" ET25 on my rears....

 

245 isn't too far of a stretch (depending on which tire you're talking about of course) so if it's something wider like the Dunlops then you should be fine..
