Tire inflation pressure

Information for your safety

The factory-mounted tires have been spe-
cially selected to provide optimal perfor-
mance when installed on your vehicle; if
properly cared for they will furnish a combi-
nation of tremendous safety and excellent
ride comfort.

It is not merely the tire's service life, but
also driving comfort and – above all else –
driving safety that depend on the condition
of the tires and the maintenance of the spe-
cified tire pressure.

Incorrect inflation pressure is a frequent
cause of tire damage. Tire inflation pres-
sures also have a substantial effect on your
BMW's handling response.

Check tire inflation pressures regu-
larly – at least every two weeks and

before beginning a longer trip. If you fail to
observe this precaution you may be driving
on tires with incorrect tire pressures, a con-
dition that can not only compromise your
vehicle's stability, but also lead to tire
damage and the risk of an accident.
Remember to check the inflation pressure
in your spare tire. Inflate the spare to the
highest pressure specified for any tire on
the vehicle.

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

Checking inflation pressure

The table on the next page provides the
correct inflation pressures for cool tires,
ambient temperature, in psi/kilopascal.

Vehicles with Flat Tire Monitor or TPM Tire
Pressure Monitor:
After mounting a spare tire or correcting
the inflation pressure(s) always reinitialize
the system, refer to page

Complying with tire approval
specifications

The inflation pressures in the table apply to
tire sizes and tires from BMW approved
manufacturers. Your BMW center is familiar
with these pressures. Different pressures
may be specified for tires from other
manufacturers.
