You might want to check the placard again. It has the pressures for all sizes on there (17",18",19",& 20"). The 4.6is/4.8is 20" tire is suggested 32psi front and rear, given a normal load. Your X5 with those wheels and tires should be kept at the same pressure. If you are pulling a trailer or have a heavy load, I believe the rears go up to 37psi.
