Tire inflation pressures If the driver's door is open, the infla-
tion pressures are also visible on the
door pillar. Inflation pressures are
indicated in psi (bar) with tires cold
(ambient temperature).
The inflation pressures apply to tires
from BMW-approved manufacturers;
your BMW Retailer will provide you
with this information. Higher pres-
sures may be required for tires from
other manufacturers.a
Periodically check the inflation
pressure Ð also of the spare tire Ð at
least twice each month and before
setting out on an extended trip. Failing
this, incorrect tire pressure may ren-
der the car unstable or cause tire
damage resulting in an accident.cSedan models

Information for your safetyThe factory-approved radial tires have
been selected to provide optimum
safety and driving comfort on your vehi-
cle.
In a very real sense, both tire life and
your own safety are riding on correct
tire specifications and inflation pres-
sures.
Incorrect inflation pressures are a fre-
quent cause of tire damage. To a great
extent it also influences the ability of
your BMW to hold the road.a
Check the tire pressures Ð also in
the spare tire Ð at least every two weeks,
and before every extended trip.
Incorrect inflation pressures can also
lead to tire damage and accidents.c
Tire tread - tire damageInspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread depth.
The tread depth should not be less than
0.12 in (3 mm). Otherwise there is an
increased risk of aquaplaning, even at
relatively moderate speeds and with
only small amounts of water on the
road.
We recommend that you always replace
the tires once the tread wears to 0.12 in
(3 mm). Once the tread has worn to
0.063 in (1.6 mm), tread depth indica-
tors appear.a
Never continue driving on a deflat-
ed (flat) tire. A flat tire greatly impairs
steering and braking response, and can
lead to complete loss of control over the
vehicle.
Avoid overloading the vehicle so that the
permitted load on the tires is not ex-
ceeded. This can cause overheating and
gradual internal damage. The ultimate
result can assume the form of a sudden
air loss.Unusual vibrations encountered during
normal vehicle operation can indicate
tire failure or some other vehicle defect,
as can variations in normal vehicle
response, such as a pronounced ten-
dency to pull to the left or right. Should
this occur, you should respond by
immediately reducing your speed and
carefully proceeding to the nearest
BMW Retailer or professional tire cen-
ter, or having the vehicle towed in to
have it and its tires inspected.
Tire damage (up to and including blow-
outs) can endanger the lives of both the
vehicle occupants and other road
users.c
