At least 37 to 40.......
you figure that if your OE tires (235/45/17) are at 33, then as you increase the diameter you need to increase the airpressure. I have 245/40/18s and I am running 37.....

Why would pressure need to change as the diameter of the tire decreases?
Isn't it more dependant on the weight of the vehicle than the diameter of the tire. All I can see the inner diameter changing is the actual mass of air inside the tire, but that has nothing to do with pressure.
