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, DSC and 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.<
StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel.
Do not exceed the maximum tire infla-
tion pressures specified on the tire
sidewall.
Winter tiresChoosing the right tireBMW recommends the use of winter
tires for operation under winter road
conditions. While all-season tires – with
M+S designation – provide better winter
traction than the corresponding sum-
mer tires, they generally do not achieve
the performance of winter 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. your BMW is eqipped with Run Flat
tires. These are indicated by a circular
symbol containing the letters RSC on

156
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 45 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
driving remains possible to a restricted
degree in the event of pressure drop or
even if the tire is deflated.
When mounting or replacing sum-
mer tires with winter tires, or vice
versa, use Run Flat tires since no spare
wheel is available in the event of a flat.
In this event, BMW recommends con-
sulting your BMW center. Your BMW
center has the information needed for
working with Run Flat tires and is
equipped with the necessary special
tools.<
