Tire replacement Uniform Tire Quality GradingQuality 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
Use only tires with emergency
driving characteristics as there is
no spare tire available if you get a flat.
For further information, refer to
page 135.<
Tire ageThe date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 1200 indicates that the tire was
manufactured in week 12 of 2000.
BMW recommends the replacement of
all tires when the tires are no more than
6 years old, even if a tire life of 10 years
is possible.

Wheel and tire combinations The right choice Use only BMW-approved tires with
emergency driving characteristics.
Refer to page 103.
Due to the maximum speeds this vehi-
cle can reach, the use of specific brands
and sizes is mandatory. Consult any
BMW center for details. Comply with
local/national regulations.
The correct wheel/tire combinaton
affects different sytems, such as
ABS, ATC, DSC and RDW. The function
of these systems is impaired if improper
wheel/tire combinations are used.
For this reason, use only tires made by
the same manufacturer that have the
same tread configuration and possess
emergency driving characteristics. And
after a flat tire, for instance, restore the
approved wheel-tire combination as
soon as possible.<
Codes on tires and wheels The tire codes will aid you in selecting
the correct tire.
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 150 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = up to 186 mph (300 km/h)
ZR = over 150 mph (240 km/h) For example:
Nominal width
in mm
Aspect ratio in X
Radial tire code
Rim diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)
245/45 R 18 96 W
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 stamped on light-alloy wheels:
Protect tire valves from dirt by using
screw-on valve stem caps. Dirt in the
valves frequently leads to slow leaks.
Tires with emergency driving character-
istics also possess an additional identi-
fication mark that varies by manufac-
turer, e. g.:
Bridgestone RFT
Dunlop DSST
Goodyear EMT
Michelin ZP For example:
Rim width
in inches
Code letter for
flange type
Symbol for full-drop
center rim
Rim diameter in inches
Hump on the 2 rim shoulders

Winter tires Snow chains
*
Choosing the right tireFor winter road driving, BMW recom-
mends winter tires (M+S radial belt
tires). Although all-season M+S tires
provide better winter traction than stan-
dard summer tires with H, V, W and ZR
speed ratings, they generally fail to pro-
vide the same levels of performance as
standard snow tires in winter driving.
In the interests of safe tracking and
steering response, install radial tires
made by the same manufacturer and
with the same tread configuration on all
four wheels if you elect to mount winter
tires.
Mount only winter tires that have been
approved by BMW. Any BMW center
will be glad to provide you with informa-
tion on the best winter tires for your
particular driving conditions.
Use only winter tires with emer-
gency driving characteristics as
there is no spare tire available if you get
a flat.
For further information, refer to
page 135.<
Do not exceed specified
maximum speeds
Never exceed the maximum speed
for which 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. Your BMW center
will be glad to assist you with both their
expertise and the proper equipment for
your vehicle.<
Tire condition, tire pressureOnce the tread depth on winter tires is
less than 0.16 in (4 mm), they are no
longer suitable for winter road driving,
and in the interest of safety should be
replaced.
Comply with the specified tire inflation
pressures Ð and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel.
The use of narrow-link BMW snow
chains is permissible in pairs only on
the rear wheels with winter tires with
tire size 245/45 R 18 96 H. Comply with
all manufacturer's safety precautions
when mounting the chains.
Do not activate the RDW system
while using snow chains.
Malfunction warnings and undetected
losses in pressure are possible when
driving with snow chains.
For further information, refer to
page 65.<

Storing your vehicle
If you plan on parking the vehicle
for more than three months,
please adhere the maintenance opera-
tions described below.<
Preparations for storageHave your BMW center perform the
following procedures:
1 Clean and apply a rustproofing agent
or other treatment to the engine,
engine compartment, undercarriage,
axles and major components in accor-
dance with approved repair proce-
dures. Wash the vehicle, clean the
interior and treat painted and
chromed parts. Clean the weather-
stripping around the hood, luggage
compartment and doors
2 Change engine oil and oil filter at op-
erating temperature. As an additional
corrosion protection measure, an an-
ticorrosive agent can be added to the
engine in accordance with the manu-
facturer's instructions
3 Check the coolant level and concen-
tration and top off if necessary
4 Check the fluid level of the wind-
shield washer fluid reservoir; top off
if necessary
5 Fill the fuel tank completely to pre-
vent the formation of condensation
6 Increase the tire inflation pressure to
51 psi (350 kPa).Before parking the vehicle1 Dry the parking brake and footbrake
by brake applications to prevent the
brake discs and drums from
corroding
2 Park the vehicle in a covered, dry,
and well-ventilated area. Place the
transmission in first gear or, if neces-
sary, chock the wheels to prevent the
vehicle from rolling. Do not engage
the parking brake
3 Remove the battery, charge it com-
pletely and store it in a cool (but
frost-free) room
4 Remove the hardtop and store it
separately, refer to page 95
5 Close the convertible top.During storageRecharge a battery that has been taken
out of the car every six months. If it is
not recharged, it will not be serviceable.
Every time the battery is discharged,
especially over extended periods, its
service life is reduced.
Removing the vehicle from
storageRecharge the battery if the "Magic Eye"
turns black, refer to page 136.
Then have Inspection I performed by
your BMW center, including a brake
fluid replacement, if necessary. Refer to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).

Changing a wheel Safety tiresYour BMW Z8 roadster is equipped
with safety tires.
The safety tires are made of self-sup-
porting tires and customized wheel
rims. Reinforcing the tires makes sure
that they remain upright and still drive-
able to a limited degree even in the
event of loss of pressure. Your vehicle
is equipped with a tire pressure monitor
that signals you in case of a flat tire.
In the event of tire failure The red indicator lamp on the instru-
ment panel will flash in the event of a
flat tire. In addition, a gong will sound.
Refer to page 65.
Carefully reduce speed to less than
50 mph (80 km/h), avoiding any hard
braking or steering maneuvers while
doing so.
You will still be able to drive about
155 miles (250 km) on your safety tire,
until you can get to a safe place to park,
a gas station, or to your nearest BMW
center. Under minimum vehicle loading,
it could conceivably last more than
155 miles (250 km) sein.
If you cannot immediately determine
which tire is defective just by looking
at it, then check the tire pressure in all
four tires.Have your BMW center replace
your tires. For safety reasons, do
not have safety tires repaired. Your
BMW center has been trained to work
with the safety tires and is equipped
with the necessary special tools.<
If necessary, please have your
BMW center switch the tires on
your vehicle from summer to winter
tires, or the reverse.<

Deceleration sensors continuously
monitor the acceleration forces acting
upon the vehicle. If, as the result of a
frontal collision, a deceleration is
reached at which the protection of the
safety belts alone is no longer adequate,
the gas generators of the driver and
passenger airbags are ignited. However,
the passenger airbag is only triggered if
an additional sensor has recognized
that the passenger seat is occupied.
In the event of a side collision, only the
side airbags will be triggered if neces-
sary. And only that airbag for that side
of the vehicle where the collision
occurred will be triggered.

The airbags located under the marked
covers inflate and unfold in a matter of
a few milliseconds. In this process, they
tear through the designed separation
points of the covers or press them out.
Because the inflation process must be
virtually instantaneous, it is necessarily
accompanied by a certain amount of
ignition and inflation noise. The gas
required to inflate the airbags is not
dangerous, and the associated smoke
then dissipates.
The entire process is completed within
fractions of a second.The AM frequency bands (medium-
wave, long-wave and short-wave) make
it possible to receive stations from a
great distance, because the broadcast
signals travel not only along the ground
as surface waves, but also as atmo-
spheric waves that are reflected from
the ionosphere.
Frequency-modulation (FM) provides
substantially better sound quality than
the other frequency bands. However,
because FM transmissions rely on line-
of-sight broadcast waves, their effec-
tive reception range is limited.
The limitations inherent to radio recep-
tion in a moving vehicle have been min-
imized by a number of innovative sys-
tem designs.
