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).Checking tire pressuresAll pressure specifications are indicated
in psi (kilopascal) for cold tires at
ambient temperature (refer also to the
next page).
Reactivate the Tire Pressure
Warning (RDW) after changing a
tire or a wheel. Refer to page 67.<520de008
Check tire inflation pressures
regularly Ð at least every two
weeks and before each extended
journey. Incorrect tire pressure can lead
to 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 103.
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.

Tire Pressure Warning (RDW)The conceptRDW monitors the tire pressure in all
four wheels while driving. The system
provides an alert whenever the inflation
pressure drops significantly in one of
the tires.
For RDW to "learn" the correct tire infla-
tion pressure, check the inflation pres-
sure in all tires, comparing them with
the values in the inflation pressure table
(refer to page 27), and make correc-
tions as necessary. Then activate the
system.
The indicator lamp within the in-
strument cluster flashes to alert
you to substantial pressure loss
in any of the tires.
To activate the system 1 Turn the ignition key to position 2
2 Press the switch long enough for
the indicator lamp in the instrument
cluster to light up red for a few
seconds
3 RDW carries out an automatic
initialization process while you are
driving, and stores this data to aim for
optimal conditions. This one-time
"learning" process lasts at least
10 minutes, after which the RDW is
able to detect and report a flat tire.520de117
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement.
Do not reactivate the system after
periodic corrections of inflation pres-
sures to maintain them at the levels
stored during an earlier initialization
process.

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
