But the all 24-25mm offset. (4.8stock offset is 30/45mm f/r) So no good? Can you go up but not down. Or down a little as we'll as up a little? Has any tried differs series wheel tires? Also I don't see a lot of e53's with e70 22's are these just to big? Has anyone check into this?

See the BMW wheels size chart below for current wheel off set ranges and hub sizes. As mentioned already the e70 X5 wheels have a 74.1mm center bore...so would need hubcentric rings to mount on an e53.
The newer BMWs that are being offered with AWD models...are appearing with wheels that have a higher offset range. Take note of the F01 7 series wheels (for example)...some of them are within the 30mm-41mm range (and some rear wheels may be higher as new wheels debut).
Wheels with a lesser wheel offset will be pushed out toward the fender...so depending on how wide they are...you might be able to get by using them. But I'd be concerned about the weight requirement of a cast alloy wheel from a 3 series (for example).
Someone diid mount e38 style 37 MPars onn e53 and had no problem. These are forged alloy wheels and the front 8x18 wheel has a 13mm offset andthe rear 9.5"x18" wheel has a 25mmwheel offset. So again, depending on the width of the wheel...a lesser offset might work.
Do most 4.6is/4.8is come with the optional 19" compact spare? If so, that means the area below the cargo floor has the extra vehicle trim to hold the emergency spare. This trim should be removeable which would provide space for the larger spare tire/wheel set-up that the other e53s came with.
As JDS mentioned in his post above...BMW started throwing in smaller spares (across all model lines) to save money. The first time I remember this happening was around late 2002 when aBimBrd forum member (M Wong) had ordered a 540i M-sport with EU delivery. This model came with style 37 18" MPar wheels & had first been advertised to be like the e38 sport pkg & come with five style 37 wheels. But they received a letter from BMW stating that the option was being changed and wouuld come with a 17" spare tire of a different style.
My 06 originally came with four 18" style 153 wheels, and the spare is some 17" style wheel.
If you look at the tire inflation chart on your driver's door...you should see the smallest tire size you can use (I think it's an 18" tire for the 4.6is/4.8is models). If yu do have thhe compact 19" emergency spare and you wantto go with an 18" or 19"full size spare...see if removing item #7 & #17 in the diagram below will give you the room you need. If it'slike the other e53s...this willallow you to store the full size spare over the air compressor dome below the cargo floor:
(item #7 & #17 should be removable in the 4.6is & 4.8is w/19" compact emergency spare)
