Wheels and tires
Mobility
In these cases, reduce speed immedi-
ately and have wheels and tires thor-
oughly checked. To do so , drive carefully to the
nearest BMW center or tire dealer. If necessary,
have the vehicle towed there.
O t h e r w i s e , t i r e d a m a g e c a n pose a lethal hazard
to vehicle occupants and other road users. <
Tire age
For various reasons, such as the development
of brittleness, BMW recommends tire replace-
ment after no more than 6 years, regardless of
the actual wear of the tires.
The manufacturing date of tires is contained in
the tire coding:
DOT... 3010 means that the tire was manufac-
tured in week 30 of 2010.
New wheels and tires
Have new wheels and tires mounted only
by your BMW center or by a tire dealer. If
this work is not carried out properly, there is a
danger of subsequent damage and related
safety hazards. Make sure that the new wheels
are balanced. <
Retreaded tires
BMW recommends that you do not use
retreaded tires, since driving safety may
be impaired. The causes for this include poten-
tially different tire casi ng structures and often
wide variations in tire ag e, which can result in a
limited service life. <
Correct wheels and tires
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount run-flat tires for your own safety. In the
event of a flat, no spare wheel is available. Your
BMW center will be glad to advise you.
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, which could
lead to body contact an d thus to severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot guarantee their driving
safety.<
You can inquire about the right wheel/tire com-
bination at your BMW center.
The correct combination of wheels and tires is
also necessary to ensure reliable operation of
various vehicle systems such as ABS, DSC or
FTM.
To maintain good handling and vehicle
response, use only tires of a single brand and
tread configuration. After a tire has been dam-
aged, mount the previous wheel and tire combi-
nation again as soon as possible.
Wheels with Tire Pressure Monitor
TPM electronics
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 Monito r may not be able to
detect a puncture , refer to page102. Your
BMW center will be glad to advise you.
Recommended tire brands
Certain makes of tire are recommended by
BMW for each tire size. They are marked with a
clearly visible BMW designation on the sidewall
of the tire.

MobilityWheels and tires
When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Special characteristics of winter tires
BMW recommends winter tires for driving on
winter roads or at temperatures below +45 7/
+7 6. Although all-season M+S tires provide
better winter traction th an summer tires, they
generally fail to provide th e same levels of cold-
weather performance as winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents. <
If the car is capable of speeds higher than that
permitted for the winter tires, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW center
can supply these labels.
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as possible.
Always protect tires agains t all contact with oil,
grease and fuels. Do not exceed the maximum
tire inflation pressure indicated on the sidewall
of the tire.
Swapping wheels between axles
BMW advises against swapping wheels
between the front and rear axles, even if all tires
have the same size, as this could impair driving
characteristics. If the tires are of mixed sizes,
swapping wheels betwee n the axles is not per-
missible.
Run-flat tires
The symbol identifying run- flat tires is a circle
with the letters RSC on the sidewall.
Run-flat tires comprise a conditionally self-sup-
porting tire and a spec ial rim. The reinforce-
ment in the sidewalls en sures that the tire can
continue to be used su bject to certain restric-
tions, even if depressurized.
For information on continuing to drive with a flat
tire, refer to In dication of a flat tire, page 101.
Snow chains
Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your BMW center for
more information.
Snow chains must be mounted in pairs and on
the rear wheels only. Observe the manufac-
turer's instructions when mounting snow
chains. Do not exceed a speed of 30 mph or
50 km/h.
Do not initialize the Fl at Tire Monitor if
snow chains are mounted; otherwise, the
instrument might issue an incorrect reading.
When driving with snow chains, you may find it
helpful to activate DT C temporarily, refer to
page 98.<

MobilityCare
Care
Vehicle equipment
In this chapter, all pr oduction, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehi cle, for example due to
the special options or national-market version
selected. This also app lies to safety related
functions and systems.
Care products
Regular cleaning and care contributes signifi-
cantly to the value re tention of your BMW.
BMW recommends cleaning and caring for your
vehicle with products that are approved by
BMW for this purpose.
Your BMW center will be happy to advise you on
the products and services available for cleaning
and caring for your BMW.
Original BMW CareProducts have been
material-tested, laboratory-checked and
proven in the field, and offer optimal care and
protection for your vehicle. <
Do not use cleaners that contain alcohol
or solvents as these may result in dam-
age.<
Cleaning agents can contain substances
that are dangerous or hazardous to your
health. Therefore, follow the warning and safety
instructions on the packaging. When cleaning
inside the vehicle, always open the doors or
windows of the vehicle. In enclosed areas, pro-
vide for sufficient ventilation. Only use products
designed for cleaning vehicles. <
Exterior care
Washing the vehicle
Especially during the winter months,
ensure that the vehicle is washed more
frequently. Heavy soiling an d road salt can lead
to vehicle damage. <
After washing the vehicle, apply the
brakes briefly to dry them; otherwise,
water can reduce braking efficiency over the
short term and the brake discs can corrode. <
Automatic car washes
Give preference to car washes that use cloth or
soft brushes in order to avoid paint damage.
Do not use high-pressure car washes;
otherwise, water may drip into the vehicle
around the windows. <
Before driving into a car wash, ensure that it is
suitable for your BMW. Check the following:
> Dimensions of your vehicle, refer to
page 285.
> If necessary: fold in the exterior mirrors,
refer to page 55.
> Maximum permissible tire width.
Avoid car washes with guide rail heights
over 4 in/10 cm; otherwise, there is the
danger of damaging chassis parts. <
Preparations before driv ing into an automatic
car wash:
> Unscrew the rod antenna.
> Deactivate the rain sensor to prevent
undesired wiper operation.
> Remove additional add-on parts, e.g. spoil-
ers or phone antennas, if they could be
damaged.
> Leave the remote control in the ignition
lock.

damaged tire, refer to Indication of a flat tire on
page 101.
The symbol identifying run- flat tires is a circle
with the letters RSC on the sidewall, refer to
