Check and correct the tire inflation
pressure at the earliest opportunity

Protect valve stems and valve
stem seal caps against dirt and

contamination. Dirt in valve stems is a
frequent source of gradual air loss.

Reinitialize the Flat Tire Monitor, refer
to page 96

Replace the damaged tire with a new
one as soon as possible and have the
new wheel balanced.

Driving with spare tire

On certain wheel-tire combinations,
the size of the spare tire deviates from

that of the rest of the tires. The spare tire is
fully capable of running in all load and
speed ranges. However, to recreate the
original conditions, the tire should be
replaced as soon as possible.

Run-flat tires*

You will recognize run-flat tires by a circular
symbol containing the letters RSC on the
side of the tire. They consist of self-con-
tained tires and special rims. The tire rein-
forcement ensures that the tire retains
some residual safety in the event of pres-
sure drop and driving remains possible to a
restricted degree. The vehicle is equipped
with a Flat Tire Monitor which indicates
punctures.

The reinforcement on the flanks of the
tires means that it is usually not pos-

sible to detect an air loss from outside.

Flat tire

If you have a flat tire, the indicator lamp
symbol in the Check Control will light up in
red, and a message will appear. In addition,
a gong sounds.
You can find more detailed information on
the Flat Tire Monitor on page

Reduce vehicle speed carefully to under
50 mph/80 km/h, avoiding hard brake
applications and steering maneuvers.

If the defective wheel is not recognizable as
such immediately, check the inflation pres-
sure in all four tires.

For reasons of safety, do not arrange
for run-flat tires to be repaired. Your

BMW center has the information needed
for working with these tires and is 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. You can deter-
mine the possible mileage for continued
driving on the basis of the following general
indications:

Tire inflation pressure 0 psi/kPa:
With empty vehicle approx. 90 miles/
150 km
With full payload approx. 30 miles/
50 km

Tire inflation pressure 7 psi/50 kPa to
15 psi/100 kPa:
Approx. 300 miles/500 km

Tire inflation pressure greater than
15 psi/100 kPa:
Approx. 600 miles/1,000 km.

Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. In the case

of air loss, you can expect changes in vehi-
cle handling such as reduce lane stability,
longer braking distances, and changes in
self-steering properties.
