Tire Pressure 330i confusion

Hi, I have a 330i with sports package and I just put on 225/45 R17 91H continental winter contact si tires. After the shop installed the tires the car drove like a lexus, very comfortable. I went home and checked the tire pressure and they were at 33 psi both front and rear. I looked at the manual as well as the sticker on the driver side door seal and I'm confused. The manual is telling me to pump 33 psi in the front and 41 psi in the rear. That seems pretty extreme between the front and rear. But when I look as the door seal it looks like they recommend 38 psi in the front and 45 psi in the rear which is what the manual says if I exceed 160km/h. I've attached the manual and sticker recommendation, could you guys help me with this?

I had a similar question in my thread:
http://www.e90post.com/forums/showthread.php?t=1322161

The door sticker does not match what the manual says.
In fact my sticker doesn't even match my wheel size, lol.

I wouldn't worry too much about this. i have been running around 36-38 psi in my winters for years without issue.
