The wheel cover can only be fitted by
BMW Service or a specialist work-
shop.
Wheel stud wrench and centering pin
In the toolkit underneath the luggage
compartment lid.
265/40 ZR 17 rear tires
In the event of a puncture, it may be
necessary to use the spare wheel with
a 235/45ZR17 tyre at the rear.
Although this wheel can be used
entirely satisfactorily in all load and
speed ranges, one with a tyre of size
265/40ZR17 should be fitted in its
place as soon as possible.
9 Screw in the remaining wheel
studs and tighten them all in a
crosswise pattern.
10 Lower the car, remove the jack,
insert the jack attachment point
cover with the flap at the bottom
and press it in at the top.
11 Tighten the wheel studs fully,
working in a crosswise pattern.
a
For safety reasons, the wheel
studs should be checked with a cali-
brated torque wrench without delay to
ensure that the specified tightening
torque of 100Nm (74 lb.ft.) has been
reached. If a new wheel (for instance
the spare wheel) is fitted for the first
time, check the tightening torque
again after the car has covered
1000km (about 600 miles).
c
12 Centre the wheel stud cover and
attach. Push it on and turn to the
left or right until wheel cap locks
into place. Cross-spoke wheels:
align with the arrow marked on the
wheel stud cover with the line
marked on the wheel and push on
the wheel cover.
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 your car is equipped with wheels
other than Original BMW light-alloy
wheels, make sure that the correct
wheel studs are used.
Have the flat or defective tyre repaired
or replaced as soon as possible, and
the new tyre balanced on the wheel.
