Tire inflation pressure

Information for your safety

The condition of the tires and the maintenance
of the specified tire pressure are crucial not only
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.

Checking 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 inflation pressure increases.

Check the tire inflation pressure regularly
and correct it as needed, even on the

compact wheel: at least twice a month and
before starting long trips. 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 driving stability,
but also lead to tire damage and the risk of an
accident.
Do not drive with deflated, i.e. flat tires. A flat tire
will seriously impair your vehicle's handling and
braking response. Attempts to drive on a flat tire
can lead to loss of control over the vehicle.

After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor

reset the Tire Pressure Monitor

, refer to

pages

Pressure specifications

The table on the next page provides all the cor-
rect inflation pressures for the specified tire
sizes at ambient temperature.

The inflation pressures in the table apply
to BMW-approved tire sizes and recom-

mended tire brands. Your BMW Sports Activity
Vehicle Center will be glad to supply this infor-
mation.

For correct identification of the right tire infla-
tion pressure for your tires, please note the fol-
lowing:

Tire size for your vehicle

Load status

Maximum permissible driving speed

Tire inflation pressures for speeds
up to 100 mph/160 km/h

For normal driving at speeds of up to 100 mph/
160 km/h and to achieve optimum driving com-
fort, take note of the tire inflation pressures
listed on the following page in the column for
speeds up to max. 100 mph/160 km/h and
adjust your tire pressure as needed.
These tire inflation pressures are also listed on
the door pillar and can be seen with the driver's
door open.

The maximum permissible speed for
these tire inflation pressures is 100 mph/

160 km/h. Do not exceed this speed; failure to
heed this limit can lead to tire damage and acci-
dents.

Tire inflation pressures for speeds

above 100 mph/160 km/h

In order to drive at maximum speeds
above 100 mph/160 km/h, take note of

the tire inflation pressures listed in the column
for speeds above 100 mph/160 km/h in the
table on the following page and adjust your tire
pressure as needed. Failure to due so can lead
to tire damage and accidents.
