TECHNICAL INFORMATION
A wheel lifter is recommended for easier wheel removal and installation without applying force (see applicable BMW equipment catalogue).
A wheel lifter is recommended for easier wheel removal and installation without applying force (see applicable BMW equipment catalogue).
- In vehicles with M Carbon ceramic brake: The wheel lifter must be used to install the wheel.
This process is intended to prevent damage to the brake disc.
Check
- Check lug bolts for wear.
Result
» Spots (> 30%) of the bearing surface (1) of the taper on the screw head show silvery wear.
Measure
- Replace wheel bolts.
NOTE:
TECHNICAL INFORMATION
Never use an impact screwdriver or electric screwdriver to apply and tighten the lug bolts.
The rim must rest uniformly against the brake disk.
In the case of non-original BMW lug bolts/wheel rims, it may be necessary to retighten the lug bolts on user account of setting properties (refer to the documentation from the manufacturer).
Do not apply oil to new lug bolts.
Recutting a damaged thread (wheel bolt/wheel hub) is not permissible!
