Wheels and tires
Tire inflation pressure
Information for your safety
It is not merely the tire's service life, but
also driving comfort and Ð to a great extent
Ð driving safety that depend on the condi-
tion of the tires and the maintenance of the
specified tire pressure.
Check the tire inflation pressure regu-
larly and correct it if necessary,
including the spare wheel: 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 condition that can not only
compromise your vehicle's stability, but
also lead to tire damage and the risk of an
accident.
Do not drive with deflated, 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 loss of control over the vehi-
cle.<
Checking inflation pressure
Only check tire inflation pressure when
the tires are cold. i.e. after a maximum of
2 hours' driving or when the vehicle has
been parked for at least 2 hours. When tires
are warm, the tire inflation pressure
increases.
After correcting the inflation pressure(s),
always reinitialize the Flat Tire Monitor,
refer to page 95.
Inflation pressure for original tires
The inflation pressures for your standard
tires can be found on the door pillar when
you open the driver's door.
Inflation pressure for other tire sizes
The table below provides all the correct
inflation pressures for the specified tire
sizes at ambient temperature.
For correct identification of the right
tire inflation pressure for your tires,
observe the specifications for the corre-
sponding tire size.<

Temperature
The temperature grades are A Ð the
highest Ð, B, and C, representing the tire's
resistance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel.
Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudden tire failure. The grade C
corresponds to a level of performance
which all passenger car tires must meet
under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A repre-
sent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive load-
ing, either separately or in combination,
can cause heat buildup and possible tire
failure.<
Run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the
side of the tire, refer to page 193.
M+S
Winter and all-season tires.
These have better winter properties than
summer tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects
lodged in the tread. Check the tread depth.
Tire tread
The tread depth should not fall below e in/
3 mm.
At tread depths below e in/3 mm, there is
an increased risk of high-speed hydroplan-
ing, even when only small amounts of
water are present on the road surface.As winter tires display a noticeable loss in
their ability to cope with cold-weather driv-
ing conditions once the tread wears to
below k/K in/4 mm, to ensure continued
safety you should always have such tires
replaced.
Wear indicators at the tread-groove base,
refer to arrow, are distributed over the tire's
circumference and are marked on the side
of the tire with TWI Ð Tread Wear Indicator.
These indicators signal at a tread depth
of k/FK in/1.6 mm that the legally permitted
wear limit has been reached.
Tire damage
Unusual vibrations encountered dur-
ing normal vehicle operation can
indicate tire failure or some other vehicle
defect. This can, for example, be caused
by driving over curbs.
These kinds of problems may also be
signaled by other changes in vehicle
response, such as a strong tendency to
pull to the left or right. Should this occur,
respond by immediately reducing your
speed. Carefully proceed Ð or have your
vehicle towed Ð to the nearest BMW center
or tire dealer to have the wheels or tires
inspected.
Tire damage, extending to sudden and
complete loss of pressure in extreme
cases, can pose a potentially lethal safety
hazard for the vehicle's occupants and
other road users alike.<

Replacing wheels/tires
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled pro-
fessionals only. The technicians at your
BMW center will be glad to assist you with
the required professional knowledge and
specialized equipment.<
The correct wheel and tire combination
affects various systems whose function
would otherwise be impaired, e.g. ABS or
DSC.
Have the wheel and tire assemblies bal-
anced every time either a wheel or a tire is
replaced.
BMW does not recommend the use
of retreaded tires, as otherwise driv-
ing safety may be reduced. Possible varia-
tions in the design and the age Ð which
could be substantial Ð of the carcasses can
lead to unusually rapid wear.<
The right wheels and tires
BMW recommends that you use only
wheel and tire combinations that
BMW has tested and approved for your
particular vehicle. Variations in factors such
as manufacturing tolerances mean that
even wheels and tires with identical official
size ratings could actually have different
dimensions than the approved units Ð these
differences could lead to body contact, and
with it the risk of severe accidents. If non-
approved wheels and tires are used, BMW
cannot evaluate their suitability, and there-
fore cannot be held liable for driving
safety.<
To maintain good handling and vehicle
response, use only tires of a single tread
configuration from a single manufacturer.
After a flat tire, always remember to have
the original wheel and tire combination
remounted on the vehicle as soon as pos-
sible.
Recommended tire brands
BMW tests certain tire brands for each tire
size, classifies them as road-safe and
approves them. You can find out about
these at specialized dealers or at your
BMW center. Observe any country-specific
regulations, e.g. on making a correspond-
ing entry in the vehicle documents.
The factory-mounted tires have been spe-
cially selected to provide optimized perfor-
mance when installed on your vehicle; if
properly cared for, they will provide a com-
bination of safety and excellent ride com-
fort.
Run-flat tires
If your BMW is equipped with run-flat tires,
refer to Run-flat tires, only use these tires,
as in the event of a breakdown there is no
spare wheel available.
Special characteristics of winter
tires
BMW recommends winter tires for use in
cold winter driving conditions. Although
so-called all-season M+S tires provide bet-
ter winter traction than summer tires, they
generally fail to provide the same levels of
cold-weather performance as winter tires.
When switching to winter tires, observe the
description at Tire condition, and Replac-
ing wheels/tires, refer to page 191.
Run-flat tires
If your BMW is equipped with run-flat tires,
refer to Run-flat tires, only use these tires,
as in the event of a breakdown there is no
spare wheel available.
Observing speed ratings
Never exceed the maximum speed
for which the winter tires are rated.
Unprofessional attempts by laymen to ser-
vice tires can lead to damage and acci-
dents. Have this work performed by skilled
professionals only. The technicians at your
BMW center will be glad to assist you with
the required professional knowledge and
specialized equipment.<

California Proposition 65
Warning
California laws require us to issue the fol-
lowing warning:
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the interior
furnishings in a vehicle, contain or emit
chemicals known to the State of California
to cause cancer and birth defects and
reproductive harm. In addition, certain flu-
ids contained in vehicles and certain prod-
ucts of component wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other
reproductive harm.
Battery posts, terminals and related acces-
sories contain lead and lead compounds.
Wash your hands after handling.
Used engine oil contains chemicals that
have caused cancer in laboratory animals.
Always protect your skin by washing thor-
oughly with soap and water.<
OBD connector
The Onboard Diagnostic OBD interface
socket is located on the left of the driver's
side under the instrument panel and under
a cover.
The cover has the letters OBD on it.The purpose of the OBD system is to
ensure proper operation of the emission
control system for the vehicle's lifetime.
The system monitors emission-related
components and systems for deterioration
and malfunction.
An indicator lamp informs you of the
need for service, not of the need to
stop the vehicle. However, the sys-
tems should be checked by your BMW
center at the earliest possible opportunity.
Indicator lamp for Canadian mod-
els.
Under certain conditions, the indicator
lamp will blink or flash. This indicates a
rather severe level of engine misfire. When
this occurs, you should reduce speed and
consult the nearest BMW center as soon as
possible. Severe engine misfire over only a
short period of time can seriously damage
emissions control components, especially
the catalytic converter.
When the fuel filler cap is not properly
tightened, the OBD system can
detect the vapor leak and the indicator will
light up. If the filler cap is subsequently
tightened, the indicator lamp should go out
within a few days.<
