Tire inflation pressure

Information for your safety

It is not merely the tire's service life, but
also driving safety and driving comfort
that greatly depend on the condition of
the tires and the maintenance of the
specified tire inflation pressure.

Check tire inflation pressures on a
regular basis and correct them, if

necessary, including the compact
wheel: at least twice a month and
before beginning a longer trip. If this is
not done, incorrect tire pressures can
cause driving instability and tire dam-
age, ultimately resulting in accidents.
Do not drive with a pressureless, i.e.
flat, tire, unless your vehicle is
equipped with Run Flat tires. A flat tire
greatly impairs steering and braking
response, and can lead to complete
loss of control over the vehicle.

Checking tire pressures

Only check the tire inflation pressures
of cold tires. This means after driving a
maximum of 1.25 miles/2 km or after
the vehicle has been parked for at least
2 hours. Warm tires have higher infla-
tion pressures.

After correcting the tire inflation pres-
sure, reinitialize the Flat Tire Monitor,
refer to page

Inflation pressures for original
tires

Tire pressures for the standard tires of
your vehicle are shown on the driver's
door post, visible when the door is
open.

The inflation pressures apply to BMW-
approved tire sizes and recommended
tire brands. Your BMW center will be
glad to supply this information.

Inflation pressures for other tire
sizes

The following tire pressure table shows
all tire pressures for the given tire sizes
at ambient temperature.
