Nope, because a 245/40/19 is 26.7" in diamter and a 275/35/19 is 26.6" in diameter. The difference is negligible..it's 2.5 millimeters. No different than haveing low tread in the rear. Whether or not you can fit a 275 into the fenderwell is a different story.
So both tires would be turning at the same speed. The AWD and ABS won't know it at all.
Unsure what the specs are to trip the AWD or ABS faults. With most cars, ABS is around 3% difference in rotational speed, but i don't know the specs on the G35 at all.

Width of tires doesn't matter...all that matters is how tall the tire is from the ground up.
I wish i had a diagram to better explain it. Basically, if you roll both wheels, they need to cover the same distance on the ground. In other words, if the rear wheel spins 300 times in a mile, the front needs to also spin 300 times.
Width doesnt matter...it only matters in terms of tucking up into the fender and looks.
height from ground to top of tire matters. Rolling distance.

I have a 2006 DG G35x sedan with 19" coupe Rays (8" front, 8.5" rear). I wrapped each corner in 245/40R19 Yokohama s.drives. I have experienced no problems with the VDC or AWD system. Also, there is no rubbing.
The only drawback of this setup is the inability to rotate tires.

That's where the confusion comes from.

It still matters somewhat for the ABS.
I used to toss HUGE drag radials on the back of my Mustang to go to the track for the day and the nearly 2" differnce in diameter would be great enough to fault the ABS and disable it until i put matching wheels back on.
Granted, i don't really think anyone wants to run wheels with a HUGE difference all the time. In terms of ABS, a 1/2" difference or so should still be in it's window of functionality.
When it comes to AWD, i strongly suggest you get it as close as possible. Any slippage in the transfer case due to different sized wheels is wear...plain and simple.
