Recommended tire sizes and makes
BMW tests certain tire brands for each tire
size, classifies them as road-safe and
approves them. You can find out about
these at specialized dealers or at your
BMW center. Observe any country-specific
regulations, e.g. on making a correspond-
ing entry in the vehicle documents.
The factory-mounted tires have been spe-
cially selected to provide optimized perfor-
mance when installed on your vehicle; if
properly cared for, they will provide a com-
bination of safety and excellent ride com-
fort.
Run-flat tires
In the event of replacement, use run-flat
tires, refer to page 168, as there is no spare
wheel available for flats.
For safety reasons, BMW recom-
mends that you do not have damaged
run-flat tires repaired; they should be
replaced.<
Special characteristics of winter
tires
BMW recommends winter tires for use in
cold winter driving conditions. Although all-
season M+S tires provide better winter
traction than summer tires, they generally
fail to provide the same levels of cold-
weather performance as winter tires.
Run-flat tires
If you switch from summer to winter tires,
or vice versa, use run-flat tires, refer to
page 168, as in the event of a flat tire there
is no spare tire available. Your BMW center
will be glad to advise you.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated.
Unprofessional attempts by laymen to ser-
vice tires can lead to damage and acci-
dents. Have this work performed by skilled
professionals only. The technicians at your
BMW center will be glad to assist you with the required professional knowledge and
specialized equipment.<
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as pos-
sible. Always protect tires against all con-
tact with oil, grease and fuels. Do not
exceed the maximum tire inflation pressure
indicated on the side wall of the tire.
Snow chains*
BMW only tests certain snow chains, clas-
sifies them as road-safe and approves
them. Consult your BMW center for more
information. BMW recommends using
these approved, narrow-link snow chains.
These snow chains are approved exclu-
sively for use in pairs on the rear wheels
with the tire size 245/45 R 18.
Observe the manufacturer's instructions
when mounting snow chains.
Do not exceed a vehicle speed of 30 mph/
50 km/h with the chains mounted.
Do not initialize the Runflat Indicator
after mounting snow chains.
When you are driving with snow chains, it
can be beneficial to switch off DSC briefly,
refer to page 77.<
