Run Flat tires
Run Flat tires are labeled on the sidewall
with a circular symbol containing the letters
RSC. Run Flat tires consist of self-support-
ing tires and special rims. The tire rein-
forcement 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 summer
tires with winter tires, or vice versa,
use Run Flat tires since no spare wheel is
available in the event of a flat. Your BMW
center knows how to work with Run Flat
tires and is equipped with the necessary
special tools.<
Driving with a damaged tire
When using Run Flat tires, you can con-
tinue driving cautiously at a maximum
speed of 50 mph / 80 km/h, depending on
the cargo load and the extent of tire dam-
age.
If there is a total loss of tire inflation pres-
sure, 0 psi/kilopascal, or obvious tire dam-
age, you can gauge the mileage for contin-
ued driving on the basis of the following
indications:
>With a light load:
1 person without luggage:
approx. 150 miles/250 km
>With a medium load:
1 person, luggage compartment full,
or
2 persons without luggage:
approx. 90 miles/150 km>With a full load:
2 persons, luggage compartment full:
approx. 30 miles/50 km
Drive cautiously. Do not exceed a
speed of 50 mph / 80 km/h. Be aware
that vehicle handling will be altered when
there is a loss in inflation pressure. Antici-
pate, e.g., reduced tracking during braking,
longer braking distances and changed
steering characteristics.
For safety reasons, BMW recommends not
to have Run Flat tires repaired if they are
damaged, but to consult your BMW center
in such cases.<
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. Use them in pairs on either summer
or winter tires, but only on both rear
wheels.
Comply with all manufacturer's safety pre-
cautions when mounting the chains.
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 53.<
