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, including the
spare wheel: at least twice a month and before
starting long trips. If you fail to take this precau-
tion, 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 acci-
dent. 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 vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor, refer to
page90, or reset the Tire Pressure Monitor,
refer to page92.<
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 inflation
pressure for your tires, pay attention to the fol-
lowing:>Tire sizes for your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving
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 for traveling speeds up to a max. of
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 driving
above 100 mph/160 km/h
In order to drive at maximum speeds in
excess of 100 mph/160 km/h, please
consult the relevant table on the following
pages and adjust tire pressures as necessary to
the specified pressures for speeds exceeding
100 mph/150 km/h. Otherwise, tire damage
and accidents could occur.<
Observe all national and local maximum speed
limits; otherwise, violations of the law could
occur.

Temperature
The temperature grades are A, B, and C, A
being highest, and represent the tire's resis-
tance 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 Vehi-
cle Safety Standard No. 109. Grades B and A
represent 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 loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
RSC 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 page205.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Indicates specially reinforced tires.
Tire condition
Inspect your tires frequently for tread depth,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not fall below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm.
At tread depths below 0.12 in/3 mm, there is an
increased risk of high-speed hydroplaning,
even when only small amounts of water are
present on the road surface.
Winter tires display a noticeable loss in their
ability to cope with cold-weather driving condi-
tions once the tread wears to below 0.16 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 circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the tire tread
has been driven down to the wear indicators, a
tread depth of 0.063 in/1.6 mm has been
reached.
Wheel/tire damage
Please note that low profile tires make wheels,
tires, and suspension parts more susceptible to
road hazards and consequential damages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, 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.
In these cases, reduce speed immedi-
ately and have wheels and tires thor-
oughly checked. Drive carefully to the nearest
BMW center or tire shop that works according
to BMW repair procedures with correspond-

ingly trained personnel. If necessary, have the
vehicle towed there.
Tire damage can be extremely dangerous for
vehicle occupants and other road users.<
Run-flat tires*
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire.
The run-flat tires consist of special rims and
tires that are self-supporting to a limited
degree. The tire reinforcement ensures that the
tire retains some residual safety in the event of
pressure drop and driving remains possible to a
restricted degree.
To continue driving with a damaged tire:
>When equipped with Flat Tire Monitor, refer
to Indication of a flat tire on page91.
>When equipped with Tire Pressure Monitor,
refer to Low tire pressure message on
page93.
New wheels and tires
Only have new wheels and tires mounted
by a BMW center or a tire specialist that
works in accordance with BMW guidelines and
uses appropriately trained personnel. If this
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
hazards.<
Retreaded tires
BMW does not recommend the use of
retreaded tires; otherwise, driving safety
may be reduced. Possible variations in the
design and the age – which could be substantial
– of the tire casing structures can lead to unusu-
ally 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 manufac-
turing tolerances mean that even wheels and
tires with identical official size ratings could
actually have different dimensions than the
approved units – these differences could lead to
body contact, and with it, the risk of severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot be held liable for driving
safety.<
You can ask your BMW center for the right
wheel and tire combination.
The correct wheel and tire combination affects
various systems whose function would other-
wise be impaired, such as ABS or DSC.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration 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 possible.
Wheels with electronics for
TPM Tire Pressure Monitor*
When mounting new tires or changing over
from summer to winter tires, or vice versa, only
use wheels with TPM electronics; otherwise the
Tire Pressure Monitor may not be able to detect
a flat tire, refer to page91. Your BMW center
will be glad to advise you.

Wheels and tires

Recommended tire sizes and brands
BMW recommends particular tire brands for
each tire size. You will recognize them by the
clearly visible BMW identification on the tire
sidewall.
With proper use, these tires meet the highest
standards for safety and handling characteris-
tics.
Run-flat tires
When installing new tires or when changing
from summer tires to winter tires or vice versa,
for your own safety, use run-flat tires. No spare
wheel is provided in the event of a flat. Your
BMW center will be glad to advise you.
For safety reasons, BMW recommends
that you not have damaged run-flat tires
repaired; they should be replaced.<
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 better winter trac-
tion than summer tires, they generally fail to
provide the same levels of cold-weather perfor-
mance as winter tires.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated.<
Storage
Always store wheels or tires in a cool, dry place
with as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres-
sure indicated on the side wall of the tire.
Wheel changing between axles
BMW does not recommend changing the front
wheels to the rear or vice versa as this can dam-
age handling characteristics.
Snow chains*
Only certain fine-link snow chains are tested,
classified as road-safe, and recommended by
BMW. Consult your BMW center for more infor-
mation. Use on winter tires is only permissible in
pairs on the rear wheels. Follow the manufac-
turer's instructions when installing snow
chains. Do not exceed 30 mph/50 km/h with the
chains mounted.
Do not initialize the Flat Tire Monitor after
mounting snow chains. When you are
driving with snow chains, it can be beneficial to
activate DTC briefly, refer to page88.<
