Wheels and tires
210 work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
h a z a r d s . M a k e s u re t h a t t h e n e w w h ee l s a r e b a l-
anced.<
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 casing structures and often
wide variations in tire age, which can result in a
limited service life.<
Correct 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, which could
lead to body contact and thus to severe acci-
dents. When selecting tires, also take their load
capacity into account. 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 or DSC.
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 Monitor may not be able to detect
a puncture, refer to page86. 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.
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 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.
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.<
Storage
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 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. With standard-equipment tires

and other mixed tire sizes, swapping wheels
between the axles is not permissible.
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.
Ensure that the snow chains are sufficiently
tensioned at all times. If necessary, retension as
specified by the snow chain manufacturer.
Do not initialize the Flat Tire Monitor if
snow chains are mounted, otherwise the
instrument might issue an incorrect reading.<

In the event of a malfunction, please contact
your BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.
Repairing a flat tire with the
M Mobility System
To repair a flat tire, your BMW M3 includes an
M Mobility System. With this system you can
apply a sealant to the inside of the tire to seal
the damaged section, restore the tire inflation
pressure and continue on your trip.
Safety measures in the event of a flat tire:
Park the vehicle as far away from moving
traffic as possible and on a firm surface. Switch
on the hazard warning flashers.
Apply the parking brake and engage first gear
or reverse. Have all occupants leave the vehicle and move beyond the danger zone, e. g. behind
the guard rails.
If necessary, erect a warning triangle
* or warn-
ing flasher
* at a suitable distance. Adhere to
country-specific regulations.<
Preparations
The M Mobility System is located in the cargo
bay under the floor board.
If possible, leave any foreign bodies that have
penetrated the tire in place.
Instructions on how to use the M Mobility
System can also be found on the device
itself.<
Before using the M Mobility System, fol-
low the instructions on the sealant bot-
tle.<
Remove the label with the speed restriction
from the sealant bottle and apply it to the steer-
ing wheel.
Please note the expiry date on the sealant
bottle.<

Using the M Mobility System
To repair a flat tire with the M Mobility System,
proceed as follows:
>Fill the sealant, refer to page227.
>Distribute the sealant, refer to page227.
>Produce the tire inflation pressure, refer to
page227.
Filling the sealant
Strictly follow the specified sequence,
otherwise the sealant may escape under
high pressure.<
1.Shake the sealant bottle.
2.Screw connection hose 9 onto the connec-
tor of the sealant bottle.
3.Ensure that screw 8 on the pressure gauge
is closed.
4.Unscrew the dust cap from the valve of the
defective wheel and screw filling hose 2 of
the sealant bottle onto the valve.5.Insert the sealant bottle into the housing of
the compressor so that the bottle is upright.
6.Ensure that the compressor is switched off,
position 0.
7.Insert connector 3 into the cigarette lighter
socket in the interior of the vehicle, refer to
page108.
8.With the ignition switched on:
Switch on the compressor and let it run for
approx. 3 minutes to fill the sealant. The
inflation pressure of the tire after filling is
unimportant.
9.Switch off the compressor.
10.Detach the hoses from the sealant bottle
connector and from the tire valve.
Return the M Mobility System to its storage
location in the vehicle.
Distributing the sealant
Immediately drive approx. 2 miles/3 km to
evenly distribute the sealant in the tire.
Do not exceed a speed of 35 mph/
60 km/h. If possible, do not fall below a
speed of 12 mph/20 km/h.<
Producing the tire inflation pressure
1.After driving approx. 2 miles/3 km, stop at a
suitable location.
2.Connect connection hose9 of the com-
pressor directly to the tire valve.
3.Insert connector 3 into the cigarette lighter
socket in the interior of the vehicle.

Replacing components
228 4.Adjust the tire inflation pressure to 29 psi/
200 kPa. With the ignition switched on, pro-
ceed as follows:
>To increase the inflation pressure:
Switch on the compressor, position I. To
check the current inflation pressure set-
ting, briefly switch off the compressor.
Do not let the compressor run for
more than 10 minutes, otherwise the
device will overheat and may be dam-
aged.<
>To reduce the inflation pressure: turn
screw 8 on the pressure gauge.
If the inflation pressure is not maintained,
drive the vehicle a second time, refer to
Distributing the sealant. Then repeat steps 1 to
4.
Use of the M Mobility System may be ineffec-
tual for tire damage larger than approx. 0.16 in/
4 mm. Please contact the nearest BMW center,
refer to page230, or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel if the tire can-
not be made roadworthy with the M Mobility
System.<
The tire inflation pressure must be at least
29 psi/200 kPa. If it is not, do not continue
driving.<
Continuing your trip
Do not exceed the maximum allowable
speed of 50 mph/80 km/h to avoid the risk
of an accident.<
Reinitialize the Flat Tire Monitor, refer to
page85 for more information.
Have the faulty tire and the sealant bottle of the
M Mobility System replaced as soon as possi-
ble.<
