Tire identification marks
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.
Tire size
Speed letter
T = up to 118 mph/190 km/h
H = up to 131 mph/210 km/h
V = up to 150 mph/240 km/h
W = up to 167 mph/270 km/h
Y = up to 186 mph/300 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of
the U.S. Department of Transportation.
DOT code:
Tire age
The tire's date of manufacture is indicated on
the sidewall:
DOT ... 3305 indicates that a tire was manufac-
tured in week 33 of the year 2005.
BMW recommends replacing all tires at least
every 6 years, even if some tires may last for
10 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one
and one-half, 1γ, times as well on the govern-
ment course as a tire graded 100. The relative
performance of tires depends upon the actual
conditions of their use, however, and may
depart significantly from the norm due to varia-
tions in driving habits, service practices and dif-
ferences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
These grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac-
teristics.< e.g.

Temperature
The temperature grades are A, the highest, 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 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
separately 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 page188.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and foreign objects lodged in
the tread, and 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 noticeably loose their suitability for
winter use below a tread depth of 0.16 in/4 mm.
New tires should be mounted in the interest of
safety.
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
is worn down to the wear indicators, then the
legally permissible tread depth limit of 0.063 in/
1.6 mm has been reached.
Wheel/tire damage
Please note that low-profile tires cause wheels,
tires and suspension parts to be more suscep-
tible to road hazards and consequential dam-
ages.
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 your speed imme-
diately and have the wheels and tires
inspected immediately. To do this, carefully
drive to the nearest BMW center or a special-
ized tire dealer that works in accordance with
BMW guidelines and uses appropriately trained
personnel. Have the vehicle towed to the repair
shop if necessary. Tire damage can be
extremely dangerous to vehicle occupants and
other road users.<

Wheels and tires
188
Run-flat tires
You will recognize run-flat tires by the circular
symbol containing the letters RSC on the side
of the tire.
Run-flat tires consist of self-contained tires and
special rims. The sidewall reinforcement
ensures that the tire retains some residual
safety in the event of pressure drop and driving
remains possible to a restricted degree.
For continued driving with damaged tires, refer
to Indication of a flat tire, page89.
New wheels and tires
Only have new wheels and tires mounted
by a BMW center or a repair shop that
works in accordance with BMW guidelines and
uses appropriately trained personnel. If this
work is performed inexpertly, there is a danger
of damage and associated safety risks. Make
sure that the new wheels are balanced.<
Retreaded tires
BMW does not recommend the use of
retreaded tires; otherwise, driving safety
may be reduced. Potentially substantial varia-
tions in the design and the age of the carcasses
can result in a reduced service life.<
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 find out the right wheel-tire combina-
tion from your BMW center.
The right wheel-and-tire combination is
another vital factor in ensuring reliable opera-
tion of various vehicle systems such as ABS
and DSC.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. After a tire is
damaged, always remember to have the original
wheel and tire combination remounted on the
vehicle as soon as possible.
Recommended tire brands
BMW recommends particular tire brands for
each tire size. You can recognize these from the
clearly visible BMW marking 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, for your own
safety, use run-flat tires. No spare wheel is pro-
vided in the event of a flat. Your BMW center will
be glad to advise you.
For safety reasons, BMW recommends
that you do 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 all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Watch speed
Always observe the maximum permissi-
ble speed for the winter tires, otherwise
tire damage may occur, which can result in acci-
dents.<
Storage
Always store wheels and 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 pressure indicated on the side wall
of the tire.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Consult your BMW center for more infor-
mation.
These snow chains are approved exclusively for
use in pairs on the rear wheels with the tire size:
>245/50 R 17 Y
>245/45 R 18 Y
Follow the chain manufacturer's instructions
when installing snow chains. Do not exceed a
vehicle speed of 30 mph/50 km/h with the
chains installed.
Do not initialize the Flat Tire Monitor after
installing snow chains as this could cause
the Flat Tire Monitor to malfunction.
When you are driving with snow chains, it can
be beneficial to switch off DTC briefly, refer to
page87.<

Replacing components

License plate lamps
Bulb 5 watts, WY 5 W
1.Push a screwdriver from the left under the
lamp and pry out the lamp toward the right.
2.Turn the bulb holder to the left by 905 and
remove.
3.Remove and replace the bulb.
Light-emitting diodes LEDs
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers, and never
stare into the unfiltered light for several
hours, as irritation of the retina could result.<
Changing a wheel
Your BMW is equipped with run-flat tires as a
standard feature. An immediate wheel change
in the event of a flat tire is therefore no longer
required.
For continued driving with damaged tires, refer
to Indication of a flat tire, page89.
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to Run-flat tires on page188.
If you have new tires mounted or switch from
summer to winter tires, or vice versa, use run-
flat tires because no spare tire is provided in case of a flat. Your BMW center will be glad to
advise you.
Also refer to New wheels and tires, page188.
The suitable tools for changing tires are
available as accessories from your BMW
center.<
Car jacking points
The jacking points for the car jack are located in
the positions shown.
Vehicle battery
Maintenance
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate.
Your BMW center will be glad to advise in all
matters concerning the battery.
Charging battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine switched off. For the connections, refer
to Jump starting on page203.
Disposal
After replacement, have old batteries dis-
posed of by your BMW center or deposit
them at a recycling center. Maintain the battery
in an upright position for transport and storage.
Always secure the battery to prevent it from tip-
ping over during transport.<
