Wheel and tire combinationsThe right choice
BMW recommends using only
wheels and tires that have been
approved by BMW for your particular
vehicle model, as otherwise body con-
tact and serious accidents can result
despite the use of the same nominal
size, e.g. due to manufacturing toler-
ances. BMW cannot evaluate all tires
and wheels on the market, and is thus
unable to guarantee that the vehicle will
continue to perform safely if unap-
proved tires and/or wheels are
mounted.<
For each tire size, BMW has assessed
the safe performance of specific tire
brands and approved them for use.
Consult any BMW center for details.
Comply with any local/national regula-
tions, for example by recording the tire
type in the vehicle documents.
The correct wheel and tire combi-
nation affects various systems
that would otherwise be impaired, for
example ABS, ASC+T/DSC and
ADB/DBC.
For this reason, use only tires of the
same manufacture and tread configura-
tion. In the event of a flat tire, for exam-
ple, remount the approved wheel and
tire combination as soon as possible.<
StorageStore tires in a cool, dry place, protect-
ing them against light whenever possi-
ble. Protect the tires against contact
with oil, grease and fuel.
Winter tiresChoosing the right tireBMW recommends winter tires – M+S
tires – for operation under inclement
winter driving conditions. While all-sea-
son tires – M+S designation – provide
better winter traction than the corre-
sponding summer tires, they generally
do not achieve the performance of win-
ter tires.
In the interest of safe tracking and
steering response, install winter tires
made by the same manufacturer and
with the same tread configuration on all
four wheels.
Never exceed the maximum
speed for which the winter tires
are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by trained
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<

Tire condition, tire pressureAt tread depths below approx.
3/16 in/4 mm, winter tires display a per-
ceptible decrease in their ability to cope
with winter driving conditions, and
should be replaced in the interest of
safety.
Comply with the specified tire inflation
pressures — and be sure to have the
wheel and tire assembly balanced
every time you change a tire or wheel.Snow chains*Only certain snow chains have been
tested by BMW and determined and
approved as roadworthy. Consult any
BMW center for details. BMW recom-
mends using only these approved fine-
link snow chains. Use them in pairs on
either summer or winter tires, but only
on both rear wheels.
Comply with all manufacturer's safety
precautions when mounting the chains.
Do not exceed a speed of 30 mph /
50 km/h when using snow chains.
You cannot mount snow chains with the
following tires:
225/50 R 16
225/45 R 17
225/40 R 18245/40 R 17

13. Wheels with full wheel covers*:
place the wheel cover with the
valve opening – see arrow – over
the valve. Use both hands to press
the cover securely onto the rim
14. Check and correct the tire inflation
pressure at the earliest opportunity.
Vehicles with Tire Pressure Monitor
(TPM)/Flat Tire Monitor:
After mounting the spare tire or
correcting the tire inflation pres-
sure, reinitialize the system, refer to
page 92.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirty
valve stems frequently lead to slow
pressure loss.
Do not place the full wheel cover
on the space-saver spare tire,
since this could damage the cover.<
The vehicle jack is designed for
changing wheels only. Do not
attempt to raise another vehicle model
with it or to raise any other type of load.
To do so could cause accidents and
personal injury.
To ensure continued safety, have the
tightness of the torque bolts checked
with a calibrated lug wrench – torque
specification: 88.5 lb ft/120 Nm – at the
earliest opportunity.<
When storing a wheel in the spare tire
recess, take care to avoid bending the
threaded rod.
If light-alloy wheels other than original
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.
Driving with the space-saver
spare tireDrive cautiously. Do not exceed a
speed of 50 mph / 80 km/h.
Be aware that vehicle handling may be
altered. Anticipate, e.g., reduced track-
ing during braking, longer braking dis-
tances and changed steering charac-
teristics when approaching limit
conditions. These handling characteris-
tics will be even more pronounced if
winter tires are mounted.
Only one space-saver spare tire
may be mounted at one time.
Mount a wheel and tire of the original
size at the earliest possible opportu-
nity.<

Run Flat tires*Run Flat tires are labeled on the side-
wall with a circular symbol containing
the letters RSC. Run Flat tires consist of
self-supporting tires and special rims.
The tire reinforcement ensures that the
tire retains some residual safety in the
event of pressure drop and driving
remains possible to a restricted degree.
The vehicle is equipped with a Tire
Pressure Monitor (TPM) or Flat Tire
Monitor, which indicate a flat tire.
Because the sides of Run Flat
tires are reinforced, a drop in infla-
tion pressure usually cannot be
detected from the outside.<
Flat tireIf there is a tire failure, the red warning
lamp symbol lights up. This visual alert
is accompanied by an acoustic warning
signal.
Additional information on the Tire Pres-
sure Monitor (TPM) or Flat Tire Monitor
is found beginning on page 92.
Reduce vehicle speed carefully to
under 50 mph / 80 km/h, avoiding hard
brake applications and steering maneu-
vers.
If it cannot be determined immediately
from the outside which wheel is defec-
tive, check the tire inflation pressure at
all four wheels.
Have Run Flat tires replaced by
your BMW center. In the interest
of safety, Run Flat tires should not be
repaired. Your BMW center has the
information needed for working with
Run Flat tires and is equipped with the
necessary special tools.<
If appropriate, please consult your
BMW center to reequip your vehi-
cle from summer to winter tires – or vice
versa.<
Driving with a damaged tireRun Flat tires allow you to continue
driving to a restricted degree at a maxi-
mum speed of 50 mph / 80 km/h
depending on the cargo load and the
extent of tire damage. You can deter-
mine the distance you may continue
driving on the basis of the following val-
ues:
>Tire inflation pressure of 0 psi/
0 kilopascal (kPa):
approx. 100 miles/150 km
>Tire inflation pressure of approx.
7-15 psi/50-100 kPa:
approx. 300 miles/500 km
>Tire inflation pressure greater than
15 psi/100 kPa:
approx. 600 miles/1,000 km.
Drive cautiously. Do not exceed a
speed of 50 mph / 80 km/h. Be
aware that vehicle handling will be
altered when there is a loss in inflation
pressure. Anticipate, e.g., reduced
tracking during braking, longer braking
distances and changed steering char-
acteristics.<
