2001 BMW Z8 rims

Information for your safetyThe factory has approved steel-belted
radials with emergency driving charac-
teristics for your vehicle. These tires
combine optimal driving safety with the
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
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 signifi-
cantly influences the roadholding 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.<
Run-flat tiresYour BMW Z8 is equipped with run-flat
tires.
The assembly consists of self-support-
ing tires mounted on specially-designed
wheel rims. Special reinforcement
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 tire pressure
monitor that signals you in case of a flat
tire.
For further information, refer to
pages 67, 135.
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 a
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

Approved wheel and tire specifications 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 67.< BMW tests certain tire brands for each tire size, classifies them as road-safe and
approves them. Your BMW center can provide further information.
Observe any regulations applicable in the country of use, e.g. requiring entry in
the vehicle documents.

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 Run-flat tiresYour BMW Z8 roadster is equipped
with run-flat tires.
The assembly consists of self-support-
ing tires mounted on specially-designed
wheel rims. Special reinforcement
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 tire pressure
monitor that signals you in case of a flat
tire.
In the event of a flat tire 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 67.
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 approx.
155 miles (250 km) on your run-flat tire,
until you can get to a safe place to park,
a gas station, or to the nearest BMW
center. Under minimum vehicle loading,
it could conceivably last more than
155 miles (250 km).
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 run-flat tires repaired. Your
BMW center has been trained to work
with the run-flat 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.<
