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-supporting
tires and special rims. The tire reinforce-
ment ensures that the tire retains some
residual safety in the event of pressure
drop and driving remains possible to a
restricted degree.
Because the sides of the Run Flat
tires are reinforced, a drop in inflation
pressure usually cannot be detected from
the outside.<

The red warning lamp in the instru-
ment cluster lights up when a tire
has failed. In addition, an acoustic
signal is heard. Refer to pages 14, 53.
1.Reduce vehicle speed carefully to
under 50 mph / 80 km/h. Avoid hard
brake applications and steering maneu-
vers
2.Do not exceed 50 mph / 80 km/h again
3.Find out which tire has been damaged;
to do so, check the tire inflation pres-
sure of all four tires at the earliest
opportunity. Refer to page 71
4.Correct the tire inflation pressure if you
wish to continue driving and if it is safe
to do so. Refer to the following section
5.Have the damaged tires changed by
your BMW center.
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.<
For safety reasons, do not have Run
Flat tires repaired.
When replacing tires or changing from
summer to winter tires – or vice versa – use
Run Flat tires only since a spare tire will not
be available in the event of a flat tire.<
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.
You can estimate the distance you can
continue driving on the basis of the follow-
ing values:
>Tire inflation pressure of 0 psi / 0 kPa:
approx. 100 miles / 150 km
>Tire inflation pressure of 7 – 15 psi
50 – 100 kPa:
approx. 300 miles / 500 km
>Tire inflation pressure greater than
15 psi / 100 kPa:
approx. 600 miles / 1,000 km.
Drive cautiously and do not exceed a
speed of 50 mph / 80 km/h. In the
event of pressure loss, changes in handling
characteristics – such as reduced stability
when braking, increased stopping dis-
tance, and altered steering response – may
occur.<
