Check and correct the tire inflation
pressure at the earliest opportunity
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 96.
Protect valve stems and valve
stem seal caps against dirt and
contamination. Dirt in valve stems is a
frequent source of gradual air loss.<

Replace the damaged tire with a new
one as soon as possible and have the
new wheel balanced.
If the defective wheel is not recognizable as
such immediately, check the inflation pres-
sure in all four tires.
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.<
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
Run-flat tires*
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/
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

restricted degree. The vehicle is equipped
with a Flat Tire Monitor which indicates
punctures.
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.<
The reinforcement on the flanks of the
tires means that it is usually not pos-
sible to detect an air loss from outside.<
