The X5 uses a two piece lug bolt that incorporates a spacer washer and features anti-corrosion coating. The tightening torque on the lug bolts is 130 Nm ± 10 Nm. Advantages of using the spacer washer include:
- Longer expansion length for the bolt.
- A better fit to the wheel
- The spacer washer is fixed to the wheel when tightening and the lug bolt turns relative to it.
