Fuel quality Tire inflation pressure The engine uses lead-free gasoline
only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI
AKI = Anti Knock Index
Do not use leaded fuels. The use
of leaded fuels will cause perma-
nent damage to the system's oxygen
sensor and the catalytic converter.<
You will find the tire inflation pressures
on the door pillar (visible with door
open).Check tire pressuresAll pressure specifications are indicated
in psi (kilopascal) for cold tires at
ambient temperature (refer also to the
next page).
Remember to reactivate the Flat
Tire Monitor after every wheel or
tire change, refer to page 67.<520de008
Check tire inflation pressures
regularly Ð at least every two
weeks and before each extended
journey. Otherwise, incorrect tire pres-
sure can lead to poor handling, 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 tire sizes
on page 104.
Your vehicle is equipped with tires that
not only meet US standards, but also
European standards. We recommend
the exclusive use of BMW-approved
tires.

Dynamic Performance Flat Tire MonitorSport mode recognitionActivating:
In ignition position 2, press the button.
The indicator lamp will come on.
Deactivating:
Whenever the indicator lamp is on, it
will go out if you press the button again.
The conceptThe Flat Tire Monitor keeps track of the
inflation pressures in all four wheels as
you drive. The system provides an alert
whenever the inflation pressure has
dropped significantly in one of the tires.
To initialize the Flat Tire Monitor with
the correct inflation pressures, start by
ensuring that all of the vehicle's tires
are inflated to the pressures specified
in the inflation pressure table on
page 27. Now you can activate the
system.
The indicator lamp within the
instrument cluster flashes to
alert you to substantial pres-
sure loss in any of the tires.
To activate the system1. Turn the ignition key to position 2
2. Press the button long enough for the
indicator lamp in the instrument
cluster to light up red for a few
seconds
3. As you drive, the Flat Tire Monitor
automatically enters the system
initialization mode in which it stores
the current pressures as its reference
figures. The initialization process
lasts for ten minutes or somewhat
longer. Once it has been completed
the Flat Tire Monitor is able to detect
and warn of flat tires.520de117

68n
Flat Tire MonitorRepeat this process after any changes
in tire inflation pressure, tire rotation or
replacement.
Do not reactivate the system after peri-
odic corrections of inflation pressures
to maintain them at the levels stored
during an earlier initialization process. In the event of a flat tireThe red indicator lamp will flash in the
event of a flat tire.
A supplementary gong is also heard.
Carefully reduce speed to less than
50 mph (80 km/h), avoiding any hard
braking or steering maneuvers while
doing so.
For additional details, refer to
page 137.
The Flat Tire Monitor cannot alert
you to severe and sudden tire
damage caused by external factors.
Another factor which the Flat Tire
Monitor does not recognize is the
balanced and very gradual pressure
loss that takes place in all tires over an
extended period of time.<
Check tire pressure on a regular
basis and correct it as required.
Refer to page 26.
Do not activate the system when driving
on snow chains or when operating the
vehicle on a closed racing circuit. False
alarms and undetected pressure loss
are both possible under these condi-
tions.
In certain circumstances, there could
be a delayed detection of any loss in
inflation pressure while driving on
snow-covered or slippery road
surfaces.
Performance-oriented driving (slip at
the drive wheels, high levels of lateral
acceleration) can also delay the
appearance of status reports in the Flat
Tire Monitor's display panel.<
System interferenceThe red indicator lamp in the instrument
cluster will stay on for as long as there
is a malfunction.
The indicator lamp will come on if the
system malfunctions.
Please contact your BMW center for
additional information.

Information for your safetyThe vehicle's factory-approved safety
tires have been specially designed to
provide optimum safety and driving
comfort on your vehicle.
It is not merely the tire's service life, but
also driving comfort and Ð above all else
Ð driving safety that depend on the
condition of the tires and the mainte-
nance of the specified tire pressure.
Incorrect inflation pressure is a
frequent cause of tire damage. It
also significantly influences the road-
holding ability of your BMW. Check tire
inflation pressures regularly (refer to
page 26), at least every two weeks and
before beginning a longer trip. If this is
not done, incorrect tire pressures can
cause driving instability and tire
damage, ultimately resulting in acci-
dents.<
Safety tiresYour BMW Z8 is equipped with safety
tires.
The assembly consists of self-
supporting tires mounted on specially-
designed wheel rims. Special reinforce-
ment elements support the sidewalls in
the event of pressure loss. Although tire
performance is then restricted, the
vehicle can still be driven on the
deflated tire for a limited distance. Your
vehicle is equipped with a Flat Tire
Monitor that signals you in case of a flat
tire.
For further information, refer to
pages 67, 137.
Tire tread Ð tire damageInspect your tires frequently for tread
depth, wear, signs of damage and for
foreign objects lodged in the tread.
Tread depth should not be allowed to
fall below 0.12 in (3 mm), even though
the legally specified minimum tread
depth is only 0.063 in (1.6 mm). At at
tread depth of 0.063 in (1.6 mm), tread
depth indicators (arrow) in the tread-
groove base will indicate that the legally
permissible wear limit has been
reached. Below 0.12 in (3 mm) tread
depth, there is an increased risk of
aquaplaning, even at relatively
moderate speeds and with only small
amounts of water on the road.390de331

Special features of 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, Y and
ZR speed ratings, they generally fail to
provide 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.
When selecting winter tires,
remember that you should never
mount anything other than safety tires,
as your vehicle is not equipped with a
spare tire.
For further information, refer to
page 137.<
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.
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
exceed a speed of 30 mph (50 km/h)
while driving with mounted snow
chains.
Do not activate the Flat Tire
Monitor when driving with snow
chains mounted. Malfunction warnings
and undetected losses in pressure are
a possibility when driving with snow
chains.

page 67.<
