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 
If your BMW is equipped with run-flat tires, 
refer to Run-flat tires, only use these tires, 
as in the event of a breakdown there is no 
spare wheel available. 
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. 
When switching to winter tires, observe the 
descriptions at Tire condition and Replac-
ing wheels/tires, refer to pages 
.
Run-flat tires 
If your BMW is equipped with run-flat tires, 
refer to Run-flat tires. Your BMW center will 
advise you if you wish to replace the tires of 
your BMW or wish to switch from summer 
to winter tires or vice versa.
If you switch from summer to winter tires, 
or vice versa, use run-flat tires, as in the 
event of a flat there is no spare wheel avail-
able.
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. 
Run-flat tires*
You will recognize run-flat tires by a circular 
symbol containing the letters RSC on the 
side of the tire. Run-flat tires consist of self-
contained tires and special rims. The tire 
reinforcement ensures that the tire retains 
some residual safety in the event of pres-
sure drop and driving remains possible to a 
restricted degree. 
If you switch from summer to winter 
tires, or vice versa, use run-flat tires, 
as in the event of a breakdown there is no 
spare wheel available. In this case, BMW 
recommends that you consult your BMW 
center. Your BMW center is qualified to 
handle run-flat tires and equipped with the 
necessary special tools.

Continuing driving with a damaged 
tire 
Driving on run-flat tires can continue, 
depending on the vehicle load and the 
severity of the tire damage, at a maximum 
speed of 50 mph/80 km/h.
In the case of complete tire pressure loss, 
0 psi/0 kPa, or obvious tire damage, you
