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.

In the event of replacement, use run-flat 
tires, refer to page 

, 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.

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.

If you switch from summer to winter tires, 
or vice versa, use run-flat tires, refer to 
page 

is no spare tire available. Your BMW center 
will be glad to advise you.

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.

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.

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 

.
