A torque wrench should always be used to tighten the wheel bolts. This ensures that the wheel bolts are tightened evenly and securely.
Caution: When replacing or removing tubeless tires, for safety reasons, it is essential to replace the valve with a rubberized body.
Loosen the wheel bolts when the car is on the ground with all wheels. To prevent the car from rolling, apply the handbrake or engage first gear.
For wheel bolts that are locked with a key, press the protective caps with a screwdriver. Insert the key into the bolt lock until it stops, with the key slot parallel to the oval recess. Turn the key 90° and remove it together with the locking part. Installation is carried out in the reverse order. When removing the key, the sleeve must be pressed against the wheel bolt. Put on the protective cap.
- a/b - wheel bolt galvanized / black chrome plated;
- c - lockable wheel bolt, black chrome plated.
If available, remove the anti-loosening device as follows: cap "1" is easily turned to the left with a wheel bolt key and removed. Then insert adapter "3" into wheel bolt "2" and unscrew the wheel bolt.
Attention: Adapter "3" must be carried in the on-board tool kit.
Raise the car.
Turn the wheel so that the valve - the lower arrow - is located at the bottom.
Before removing, mark the relative positions of the wheel disc and hub with a felt-tip pen so that when reassembling, the balanced wheel can be installed in the same position.
Please note: Depending on the design of the disc wheel, different wheel bolts are used. It is imperative that only those bolts specified by BMW are used.
When fitting light alloy wheels other than genuine BMW wheels, the corresponding wheel bolts must also be used instead of the BMW wheel bolts. It is recommended that the corresponding BMW spare wheel bolts be included in the vehicle tool kit.
Light alloy rims are protected from corrosion by a clear varnish. When replacing wheels, make sure not to damage the protective layer, otherwise restore the protective coating.
Before each wheel installation, clean the wheel disc centering area on the hub and the wheel disc mating surfaces from dirt and oil deposits. Apply a thin layer of grease for rolling bearings to the centering area.
Clean dirty bolts. Replace bolts with damaged threads or rust. Do not lubricate the threads of wheel bolts.
Before installing the disc wheel, insert the mounting pin, which is in the on-board tool kit, into the upper threaded hole for the wheel bolt. After screwing in several wheel bolts, remove the mounting pin.
Tighten the wheel bolts in a crisscross pattern in several steps. The tightening torque for all wheel bolts is 100 Nm.
Caution: If the wheel bolts are tightened one-sidedly or unevenly, increased stress may occur in the wheel and/or wheel hub. If new disc wheels are installed, tighten the wheel bolts to the specified tightening torque after 1,000 km.
