Wheels from BMW iX on BMW X7: compatible?

Yes, the hub is identical

Same 5x112 PCD and same 66.6 mm centre bore: wheels from BMW iX bolt on and centre on BMW X7 without rings. You still need to check the offset and tyres, detailed below.

Wheel by wheel: offset and tyres

Each original wheel from BMW iX is compared with the one from BMW X7 of the same diameter: how much closer the wheel gets to the shock absorber or how far it sticks out of the wheel arch, and whether the tyre keeps the same overall diameter.

Before fitting the wheels

An identical hub is not enough: offset, width and diameter change the position of the wheel, and larger calipers can touch a smaller wheel. Original wheels often use bolts or nuts with a specific seat: keep the fixings intended for the wheel, with the thread of BMW X7 (M14x1.25), tightened to the torque shown on its vehicle page. Finally, check that the size is among the approved fitments for your vehicle. This comparison is for guidance only: have the fitting approved by a professional.
