Tire inflation pressure
Check tire inflation pressures
regularly – at least every two
weeks and before beginning a longer
trip. Incorrect tire pressure can other-
wise lead to driving instability, tire
damage and accidents.<
Comply with tire approval
specificationsThe inflation pressures in the table
apply to tires made by BMW-approved
manufacturers. Your BMW center is
familiar with these pressures. Higher
pressures may be specified for tires
made by other manufacturers. You
will find a list of approved tires on
page 103.
Your vehicle is equipped with tires that
meet both US standards and European
standards. We recommend the exclu-
sive use of BMW-approved tires.
Have winter tires mounted at your
BMW center or a tire dealer.< BMW Tires
All tire pressures are in
psi (kilopascals [kPa])

Winter operationThe onset of winter is often accompa-
nied by rapid changes in weather.
Adaptations in driving style should be
accompanied by preparations on the
vehicle itself to ensure that your vehicle
operation through the winter remains
safe and trouble-free.CoolantEnsure that the coolant contains the
year-round 50 : 50 ratio of water and
antifreeze with corrosion inhibitor.
This mixture provides protection
against freezing down to approx.
– 34 7 (– 37 6). Replace the coolant
every three years.LocksBMW door lock deicer can be used to
free the doors if they are frozen. This
deicer also contains lubricant.
After using deicer, treatment with BMW
lock cylinder grease is recommended.
Rubber seals and components In order to prevent freezing, apply BMW
rubber treatment or silicone spray to
weather-stripping on the doors, hood,
luggage compartment and to convert-
ible top seals.
A full range of car-care products is
available from your BMW center.< Snow chainsMount the BMW snow chains
* only in
pairs on the rear wheels only. Comply
with the manufacturer's safety precau-
tions. Do not exceed a speed limit of
30 mph (50 km/h) when driving with
chains. As an exception in this situa-
tion, we recommend that you deacti-
vate the DSC and RDW when snow
chains are mounted. Refer to page 65
or page 67.
Starting offWhen starting from a full stop or
"rocking" free in deep snow, we recom-
mend that you deactivate the DSC
system. Refer to page 65.Driving on low-traction road
surfacesUse smooth, gentle pressure to control
the accelerator pedal. Avoid excessive
engine speeds and shift to the next
higher gear at an early point. Shift down
into the next lowest gear when
approaching uphill or downhill grades.
Maintain an adequate distance between
yourself and the vehicle ahead.Braking Winter road conditions substantially
reduce the traction available between
the tires and the road surface.
Remember that – in every situation –
braking distances will be significantly
longer as a result of this.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response.

Wheel and tire combinationsThe right choice
Use only wheels and tires
approved by BMW for the corre-
sponding vehicle model, as otherwise
the tires may make contact with the
body as the result of tolerances despite
the same nominal size being used,
leading to serious accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.<
For wheel and tire specifications
approved by BMW, refer to the informa-
tion on page 103.
The correct wheel and tire combi-
nation affects different systems
such as ABS, DSC and RDW. The func-
tion of these systems is impaired if
improper wheel and tire combinations
are used.
For this reason, use only tires of the
same brand and tread pattern on the
vehicle and, for example, restore the
approved wheel and tire combination
following a flat tire as soon as
possible.<
Codes on tires and wheelsThe code on tires has the following
meaning.
Codes on radial tires:
The speed rating indicates the
approved maximum speed for the tire.
Summer tires:
S = up to 112 mph (180 km/h)
T = up to 118 mph (190 km/h)
H = up to 130 mph (210 km/h)
V = up to 149 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = up to 186 mph (300 km/h)
ZR = over 149 mph (240 km/h) Example:
Nominal width
in mm
Aspect ratio in %
Belt rating ID code
for radial tires
Wheel diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)
205/60 R 15 91 H
All season and winter tires:
Q M+S = up to 100 mph (160 km/h)
T M+S = up to 118 mph (190 km/h)
H M+S = up to 130 mph (210 km/h)
Codes on light-alloy wheels:
Protect valve inserts against dirt by
using screw-on valve caps.
Dirt in the valves frequently leads to
slow leaks.Storage Store tires in a cool, dry place,
protecting them against light whenever
possible. Protect the tires against
contact with oil, grease and fuel. Example:
Rim width
in inches
Code letter for
flange type
Symbol for full-drop
center rim
Rim diameter in inches

Special features of winter tires Snow chains
*
Choosing the right tireBMW recommends winter tires (M+S
radial tires) for operation under
inclement winter driving conditions.
While so-called all season tires (M+S
designation) provide better winter trac-
tion than summer tires with the load
ratings H, V, W, Y and ZR, they gener-
ally do not achieve the performance of
winter tires.
In the interests of sure tracking and safe
steering response, mount winter tires
which are made by the same manufac-
turer and which have the same tread
pattern at all four wheels.Comply with recommended speed
Never exceed the maximum
speed for which the winter tires
are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire pressureOnce the tire wears to below 0.16 in
(4 mm), winter tires display a percep-
tible decrease in their ability to cope
with winter driving conditions, and
should be replaced in the interest of
safety.
Comply with the specified tire inflation
pressures – and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.The use of narrow-link BMW snow
chains on winter tires is approved only
in pairs and only on the rear wheels.
Comply with all manufacturer's safety
precautions when mounting the chains.
Deactivate the Tire Pressure
Warning (RDW) when using snow
chains. The snow chains can lead to
malfunction warnings and undetected
losses in pressure.

Wheel with asymmetrical hump
(AH)The rim design with a so-called asym-
metrical hump results in a clearly
extended holding of the tire on the rim
in the case of a leak compared to the
usual symmetrical hump, so that the
vehicle can be braked to a stop more
safely. Another advantage of the asym-
metrical hump is that no special tire is
required.

Caring for your vehicleWhen using an automatic car wash, be
sure that:
>The car wash system is suited for the
dimensions of your vehicle.
>No damage will occur on vehicles
with attached body accessories (such
as spoilers or antennas). Consult the
car wash operator if necessary.
>The wheels and tires of your vehicle
cannot be damaged by the convey-
ance devices of the car wash system.
>The vehicle is cleaned with minimum
brush pressure, and ample water is
available for washing and rinsing.
Parts of the vehicle which are inacces-
sible to the automatic washer – such as
door sills, door and hood edges, etc. –
should be cleaned by hand.
In the winter months, it is especially
important to ensure that the vehicle is
washed on a regular basis. Large quan-
tities of dirt and road salt are difficult to
remove, and they also cause damage to
the vehicle.If spray wands or high-pressure
washers are used, be sure to
maintain an adequate distance between
the spray source and the vehicle's
surface. Inadequate distance and
excessive pressure can damage or
weaken the finish, making it more
susceptible to subsequent attack. In
addition, moisture could penetrate to
vehicle components, leading to long-
term damage.<
When cleaning the headlamps,
please observe the following:
>Do not rub dry (this causes scratches)
and never use abrasives or strong
solvents to clean the covers.
>Remove dirt and contamination (such
as insects) by soaking with BMW Car
Shampoo and then rinsing with plenty
of water.
>Always use a deicer spray to remove
accumulated ice and snow – never
use a scraper.<
After washing the vehicle, apply
the brakes briefly to dry them.
Braking efficiency might otherwise be
reduced by the moisture and the brake
discs could also be corroded.<

Changing a wheel Repairing a flat tireThe M roadster and M coupe are deliv-
ered from the factory without a jack and
lug wrench.
Please have your BMW center switch
the tires on your vehicle from summer
to winter tires, or the reverse.
To repair a flat tire, refer to the following
pages.Safety measures in the event of a
flat tire:
Stop the vehicle as far as possible from
the flow of traffic. Turn on the hazard
warning flashers.
Turn the steering wheel to the straight-
ahead position and engage the steering
lock, engage the parking brake and
shift into 1st or reverse gear.
All passengers should be outside the
vehicle and well away from your imme-
diate working area (for instance, behind
the guardrail).
If a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all safety guidelines and regula-
tions.<
M Mobility SystemYou will find an M Mobility system in the
M roadster and M coupe, for repairing
flat tires. With the aid of this system,
you can apply a liquid sealant to the
inside of the tire, thereby sealing off the
damaged area, and then continue
driving.
The M Mobility system makes trans-
porting a spare wheel superfluous,
thereby reducing the amount of weight
you have to carry around.
