Tire inflation pressure

Information for your safety

It is not merely the tire's service life, but
also driving comfort and – to a great extent
– driving safety that depend on the condi-
tion of the tires and the maintenance of the
specified tire pressure.

Check the tire inflation pressure regu-
larly and correct it if necessary: at

least every two weeks and before begin-
ning a longer trip. If you fail to observe this
precaution, you may be driving on tires with
incorrect tire pressures, a condition that
can not only compromise your vehicle's
stability, but also lead to tire damage and
the risk of an accident.

Checking tire inflation pressure

Only check tire inflation pressure when the
tires are cold. This means after a maximum
of 1.25 miles/2 km driving or when the
vehicle has been parked for at least
2 hours. When tires are warm, the tire infla-
tion pressure increases.

After correcting the inflation pres-
sure(s), always reinitialize the Flat Tire

Monitor, refer to page

Inflation pressures for original tires

The tires must be at ambient temperature.
The inflation pressures, provided on a label
affixed to the B-pillar, are visible when the
driver's door is open.

Inflation pressure for other tire sizes

The tables below provide all the correct
inflation pressures for the specified tire
sizes at ambient temperature.

For correct identification of the right
tire inflation pressure for your tires,

observe the specifications for the corre-
sponding tire size.

Observe tire size

The specified pressures apply to tire sizes
approved by BMW and recommended tire
makes; your BMW center will be glad to
provide information.
