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 tire

*

: at least twice a month and before

starting long trips. Otherwise driving instability
or tire damage, and therefore accidents, can
result from incorrect tire inflation pressures.
Do not drive with depressurized, i.e. flat tires,
except run-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 a loss of control over the vehicle.

<

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

page

94

, or reset the Tire Pressure Monitor,

refer to page

96

.

Pressure specifications

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

The inflation pressures apply to the tire
sizes and tire brands respectively

approved and recommended by BMW; a list of
these is available from your BMW center.

For correct identification of the right tire infla-
tion pressure for your tires, observe the follow-

Maximum allowable driving speed

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

For normal driving up to 100 mph/160 km/h,
adjust pressures to the respective tire inflation
pressures listed on the following pages in the
column Traveling speeds up to max. 100 mph/
160 km/h to achieve optimum driving comfort.
These pressure specifications can be found on
the door post when you open the driver's door.

The permissible top speed for these tire
inflation pressures is 100 mph/160 km/h.

Do not exceed this speed, otherwise tire dam-
age and accidents may result.

<

Tire inflation pressures for speeds
above 100 mph/160 km/h

In order to drive at maximum speeds in
excess of 100 mph/160 km/h, please

observe, and, if necessary, adjust tire pressures
for speeds exceeding 100 mph/160 km/h from
the relevant table on the following pages. Oth-
erwise tire damage and accidents could
occur.

<

Observe all national and local maximum speed
limits, otherwise violations of the law could
occur.
