Winter tires
Choosing the right tire
BMW recommends Run Flat winter tires –
M+S – for operation under inclement winter
driving conditions. While all-season tires
with the M+S identification mark do indeed
possess better winter traction than summer
tires that have the H, V, W, Y and ZR speed
ratings, they generally do not provide the
same levels of performance as true winter
tires.
In the interests of sure tracking and safe
steering response, mount winter tires
which are made by the same manufacturer
and which have the same tread configura-
tion on all four wheels.
Your BMW is equipped with Run Flat tires.
Please consult your BMW center if you
wish to replace the tires of your BMW or
change from summer to winter tires, or vice
versa.
When replacing tires or changing from
summer to winter tires – or vice versa –
use only Run Flat tires since a spare tire will
not be available in the event of a flat tire.<
Comply with recommended speed
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 pro-
fessionals only. Any BMW center has the
required technical knowledge and the
proper equipment and will be happy to
assist you.<
Tire condition, tire pressure
Once the tire wears to below 3/16 in /
4 mm, winter tires display a perceptible
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 assemblies balanced every time
you change the tires.
Storage
Store tires in a cool, dry place, protecting
them against light whenever possible. Pro-
tect the tires from contact with oil, grease
and fuel.
Snow chains*
Only certain types of snow chains have
been tested by BMW, classified as road-
safe and approved. Consult your BMW
center for more information. BMW recom-
mends using only approved fine-link snow
chains.
Their use is only permitted in pairs on the
winter tires on the rear wheels. Comply
with all manufacturer's safety precautions
when mounting the chains.
You cannot mount snow chains on the fol-
lowing tires:
245/40 R 17
255/35 R 18
Do not exceed a speed of 30 mph /
50 km/h when using snow chains.<
Do not initialize the Flat Tire Monitor
after snow chains have been
mounted.
When driving with snow chains, it may be
useful to deactivate the DSC briefly. Refer
to page 51.<

Changing a wheel
Run Flat tires
Your BMW is equipped with Run Flat tires.
Therefore, the wheel no longer has to be
changed immediately in the event of a loss
in inflation pressure.
Run Flat tires are labeled on the sidewall
with a circular symbol containing the letters
RSC. Refer to page 75.
BMW recommends that you consult your
BMW center if you wish to replace the tires
of your BMW, or change from summer to
winter tires or vice versa.
Your BMW center knows how to work with
Run Flat tires and is equipped with the nec-
essary special tools.
When replacing tires or changing
from summer to winter tires – or vice
versa – use only Run Flat tires since a spare
tire will not be available in the event of a flat
tire.<
Jacking points
The jacking points are located at the posi-
tions indicated in the illustration.
Your BMW center can provide you
with a suitable jack.<
Battery
Maintenance
The battery is completely maintenance-
free. This means that the original electro-
lyte will normally last for the service life of
the battery under moderate climatic condi-
tions.
