BMW seems to recommend against rotation, but most of the X3's in the US come with asymmetrical tires (you can tell because tires are marked inside and outside on side walls), this means they are not directional, so in my book I am rotating, they can be moved front to back and left to right. If you have the same size on all 4 corners, you could do the typical cross over from front to back and move the backs straight to the front.

On my X5, the fronts wore bad and cupped and got really noisy from not rotating them - tire manufacturer recommended rotating the fronts from side to side (as my rears were different sizes) to even out the wear and cupping and stop from getting the noise with the new set. Unfortunately, BMW's run a lot of camber, so they tend to wear the insides of the tires more than the outsides and there is nothing that you can do about that!
