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,
under-inflation, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.<
RSC: Run Flat tires
Run Flat tires are labeled on the sidewall with a
circular symbol containing the letters RSC.
Refer to page82.
M+S
Winter and all-season tires.
These have better winter performance proper-
ties 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
Tread depth should not be allowed to go below
1/8 in / 3 mm even though in Europe, for exam-
ple, the legally specified minimum tread depth
is only 1/16 in / 1.6 mm. Below 1/8 in / 3 mm
tread depth, there is a very high risk of hydro-
planing, even with only small amounts of water
on the road and at relatively moderate speeds.At tread depths below approx. 1/6in/ 4mm,
winter tires display a perceptible decrease in
their ability to cope with winter driving condi-
tions, and should be replaced in the interest of
safety.
Tread wear indicators in the tread-groove base,
see arrow, are distributed around the wheel cir-
cumference and are labeled on the tire sidewall
as TWI, Tread Wear Indicator. At a tread depth
of 1/16 in / 1.6 mm, the indicators signal that the
legally permissible wear limit has been reached.
Wheel/tire damage
Due to low-profile tires, please note that
wheels, tires and suspension parts are
more susceptible to road hazards and conse-
quential damages.<
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle malfunction. This type of
problem can be caused by contact with curbs,
etc. This is also true for irregularities in the vehi-
cle's handling characteristics, such as a pro-
nounced tendency to pull to the left or right.
Should this occur, respond by immedi-
ately reducing your speed. Proceed care-
fully to the nearest BMW center or professional
tire center, or have the vehicle towed there.
Tire damage up to and including sudden and
complete air loss can pose an extreme hazard
for both vehicle occupants and other road
users.<

Wheels and tires
82
Run Flat tires fitted
Run Flat tires are labeled on the sidewall with a
circular symbol containing the letters RSC.
Run Flat tires consist of self-supporting tires
and special rims. The tire reinforcement
ensures that driving remains possible to a
restricted degree in the event of pressure drop
or even if the tire is deflated.
Wheel and tire replacement
Have new wheels and tires mounted only
by a BMW center or specialized tire shop
that works according to BMW requirements
with the appropriately trained personnel. Work
that is improperly carried out could result in
consequential damage and pose safety haz-
ards. Make sure that the new wheels are bal-
anced.<
BMW advises against using retreaded
tires, since driving safety may be
impaired. This is due to possible variations in
casing structures and, in some cases, to their
extreme age, factors which can lead to a
decrease in their durability.<
The correct wheels and tires
BMW recommends using only wheels
and tires that have been approved by
BMW for your particular vehicle model, as oth-
erwise body contact and serious accidents can
result despite the use of the same nominal size,
e.g. due to manufacturing tolerances. If non-
approved wheels and tires are used, BMW can-
not evaluate their suitability, and therefore can-
not be held liable for driving safety.
nations for your vehicle.
The correct wheel and tire combination also
affects other systems which would otherwise
be impaired, for example ABS or DSC.
To maintain good handling and vehicle
response, use only tires of a single brand and
tread configuration. In the event of a flat tire,
remount the previous wheel and tire combina-
tion as soon as possible.
Recommended tire brands
BMW tests certain tire brands for each tire size,
classifies them as road-safe and approves
them. You can best find out about these at a
specialized shop, particularly your BMW center.
Observe any country-specific regulations, e.g.
on making a corresponding entry in the vehicle
documents.
The factory-approved radial-ply tires are
matched to your vehicle and have been
selected to provide optimum safety and driving
comfort when used properly.
Run Flat tires
When mounting new tires or replacing summer
tires with winter tires, or vice versa, use Run Flat
tires since no spare wheel is available in the
event of a flat. Your BMW center will be glad to
provide you with more information.
For safety reasons, BMW recommends to
have Run Flat tires replaced, not repaired,
if they are damaged.<
Special characteristics of winter tires
BMW recommends the use of winter tires for
operation under winter road conditions. While
all-season tires with M+S designation provide
better winter traction than summer tires, they
generally do not achieve the full performance of
winter tires.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated. Unpro-
fessional attempts by laymen to service tires

can lead to damage and accidents. Have this
work performed by skilled professionals only.
The technicans at your BMW center will be glad
to assist you with the required professional
knowledge and specialized equipment.<
Storage
Store tires in a cool, dry place, protecting them
against light whenever possible. Protect the
tires from contact with oil, grease and fuel. Do
not exceed the maximum tire inflation pres-
sures specified on the tire sidewall.
Snow chains*
Only certain types of snow chains have been
tested by BMW, classified as road-safe and
approved. Consult your BMW center for more
information. BMW recommends using only
approved fine-link snow chains. Use them in
pairs on either summer or winter tires, but only
on both rear wheels.
Comply with all manufacturer's safety precau-
tions when mounting the chains.
Do not exceed a speed of 30 mph / 50 km/h
when using snow chains.
Do not initialize the Flat Tire Monitor after
snow chains have been mounted.
When driving with snow chains, it may be useful
to deactivate the DSC briefly. Refer to
page51.<

Replacement procedures
94 Please contact a BMW center in case of a mal-
function.
License plate lamps
5 watt bulb
1.Push out the lamp with a suitable object and
remove it
2.Replace the bulb.
Snap the lamp back into place.
Light-emitting diodes LEDs
Control elements, display units and other inte-
rior equipment in your vehicle use a light-emit-
ting diode behind a cover as a light source.
These light-emitting diodes are similar to con-
ventional lasers.
Do not remove the covers, and do not
look directly at the unfiltered light for sev-
eral hours. Otherwise, it can lead to retinal irrita-
tion of the eye.<
Changing a wheel
Run Flat tires
Your BMW is equipped with Run Flat tires.
Therefore, the wheel no longer has to be
changed immediately in the event of a loss in
inflation pressure.
Run Flat tires are labeled on the sidewall with a
circular symbol containing the letters RSC.
Refer to page82.
BMW recommends that you consult your BMW
center if you wish to replace the tires of your
B MW , o r change from summe r to winter tire s o r
vice versa.
Your BMW center knows how to work with Run Flat tires and is equipped with the necessary
special tools.
When mounting or replacing summer
tires with winter tires, or vice versa, use
only Run Flat tires since no spare wheel is avail-
able in the event of a flat.<
Jacking points
The jacking points are located at the positions
indicated in the illustration.
Your BMW center can provide you with a
suitable jack as an accessory.<
Vehicle battery
Maintenance
The battery is completely maintenance-free.
This means that the original electrolyte will nor-
mally last for the service life of the battery under
moderate climatic conditions. Your BMW cen-
ter will be happy to advise you if you have any
questions concerning the battery.
Indicator lamp
The indicator lamp lights up:
The battery is no longer being charged.
The alternator drive belt is defective or
there is a malfunction in the charging circuit of
the alternator. Please contact the nearest BMW
center.
If the drive belt is defective, pull over and
switch off the engine immediately to pre-
vent overheating and serious engine damage.
If the onboard supply voltage drops to a very
low level, increased steering effort may also be
necessary.<
