Information for your safetyFactory-approved steel-belted radials
with emergency driving characteristics
are meant for your vehicle, offering
optimum driving safety as well as the
driving comfort you desire.
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 con-
dition of the tires and the maintenance
of the specified tire pressure.
Incorrect inflation pressure is a frequent
cause of tire damage. It also signifi-
cantly influences the roadholding ability
of your BMW.
Check tire inflation pressures reg-
ularly (refer to page 24), at least
every two weeks and before beginning
a longer trip. If this is not done, incor-
rect tire pressures can cause driving
instability and tire damage, ultimately
resulting in accidents.<
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.
For further information, refer to
pages 65, 135.

Snow chains
*
It is impossible to install snow chains
when using summer tires 275/40 R 18
99 W.
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.<
The use of rims and wheel bolts
that do not meet the specifications
of the original factory-installed equip-
ment will affect the safe operation of
your vehicle and may cause an accident
and personal injury.
Never mix tires of different design, such
as steel-belted radials with radial bias
belted or bias-ply tires, etc. Mixing tire
types will adversely affect roadholding
and can lead to loss of vehicle control.<

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.<
