I run 33 all around in most of my cars. As others have mentioned, the recommended pressure induces understeer. It helps keep the average American driver out of trouble since understeer is easier to control than oversteer if you have no idea what you're doing (which most don't since our driver training sucks). Same reason BMW went with with a staggered setup on the 96 M3 since so many people were crashing their 95s.
46 is insanely high though. When I first bought the zhp, I was at a tire shop and the tech looked at me weird and explained that he has to air up to what the sticker says for liability reasons. I told him ok, I left the shop... and as soon as I could, I pulled over, looked at the sticker in shock and drained 13 psi from the rear tires.
After I got them mounted and balanced they were 48 front and rear...lol. I could tell....

I ran on 32 all around last year when I got the car.....decided to go 34, 38 this year and my mpg's went from 22.3 to 23.9. Better feel too!

33 - 35 all around. Low PSI upfront makes the wheels more prone to bents. BMW's recommended setting gives way too much under-steer for my liking.
The tire pressures on the door plate were written buy lawyers. They want higher pressures
for liability reasons.
Inside your drivers manual is where you will find the proper tire pressures.

I think I run 33/38 or something like that.
I'm having trouble finding a good pressure to run at for my 17 winters though. IIRC, i ran 33-34 PSI in them and I have center tire wear :/
Seems unusual for this wear to be due to those tire pressures. For winter I have 17" wheels with 205/50 tires and run 34 all around. Wear has been fine. Agree that for summer tires the 32/38 setting creates too much understeer. Prefer 36/38.I'm having trouble finding a good pressure to run at for my 17 winters though.
