Go with what your manual says.

Purely from memory, I think it is 35 front and 41 back for speeds up to 160Km/hour (which I hope suffices for your winter driving needs).

The door of your car has the max pressures only for the highest speed possible (up to 210 km/h).

I put in 36psi in the rear tires and 33 in the front tires yesterday. I am pretty sure that is what it says on the pillar where the car door is.....

32/36

I find the 330i SP ride quality sensitive to tire pressure.

Actually, for winter tires 225.45.17 it says you can do 33 front, 41 back if you keep the speed under 160Km/H (checked the manual last night)

This is what I am running. We'll see if I find it too harsh in the back.
