8. Remove heavy dirt deposits from
the wheel and hub contact faces
and clean the wheel studs
9. Fit the spare wheel or compact
spare wheel, insert at least two
screws on opposite sides of the
hub and screw them in
10. Insert and screw in the remaining
wheel studs, then tighten them all,
working across the hub rather than
round it
11. Lower the car and remove the jack
12. Firmly tighten the studs alternately
on opposite sides of the hub
13. Full-width wheel covers*: place the
cover in position so that the valve
cutout, see arrow, is aligned with
the tyre valve, then press the cover
on to the wheel with both hands
14. Correct the tyre pressure at the
earliest opportunity.
Cars with tyre pressure control
(RDC):
After fitting the spare wheel and
correcting the tyre pressure, reacti-
vate the system; see page 84.
Prevent dirt from entering the tyre
valves by attaching screw-on dust
caps. Dirt in the tyre valve can often
lead to a gradual loss of pressure.
Use only the genuine BMW full-
width wheel cover, otherwise the
cover may work loose. The full-width
wheel cover must not be attached to
the compact spare wheel, otherwise it
could be damaged.
<
Use the jack only for wheel-
changing. Never attempt to raise a
different type of vehicle or any other
load with the jack, or injury and damage
to property could result.
For safety reasons, have the wheel stud
tightening torque checked without
delay, using a suitable calibrated torque
wrench correct tightening torque =
100 Nm.
<
When replacing a wheel in the spare
wheel well, make sure that the central
threaded rod in the well is not bent or
damaged.
If the car is fitted with alloy wheels not
of original BMW pattern, note that dif-
ferent wheel studs may be needed.
Have a flat tyre repaired as soon as
possible, and the wheel and tyre rebal-
anced before fitting.
