The Style 300 wheels, (if those are indeed the wheels in the photo and orig equipment), fit both the X5M and X6.



The wheels have rear wheel bore hole size same as your current 2006 4.4, but have a larger wheel bore diameter on those front wheels. Some posters have mentioned running wheel rings under wheels with larger bore hole.



Also note that the wheel lug bolts are slightly different...no idea of that fitment or if it affects wheel to hub snug down.
