Tire inflation pressureComply with tire approval
specificationsThe inflation pressures in the table
apply to tires from BMW-approved
manufacturers. Your BMW center is
familiar with these pressures. Higher
pressures may be specified for tires
from other manufacturers. You will find
a list of approved tires sizes beginning
on page 130.
Your vehicle is equipped with tires that
meet US and European standards.
We recommend the exclusive use of
BMW-approved tires.BMW Tires

For all-season tires, use the same tire inflation pressure as for summer tires.
BMW 320i, 325i, 325xi: when using the tire 205/50 R 17 93 W extra load, the
inflation pressure increases by 3 psi (20 kilopascal).
330i/330xi: when using the tires 225/45 R 17 91 W and mixed tires 225/45 ZR 17
(front) + 245/40 ZR 17 (rear) the inflation pressure decreases by 3 psi
(20 kilopascal).

Tire Pressure Control (RDC)
*
In the event of a flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, an acoustic
signal is sounded.
If this occurs, reduce vehicle speed
immediately and stop the vehicle in a
safe location. Avoid hard brake applica-
tions. Do not oversteer. Replace the
wheel and flat tire.
The space-saver spare tire is
provided for temporary use only in
the event of a tire failure. It does not
have RDC electronics and is not moni-
tored. A full-size spare tire that has the
same dimensions as the tires already
mounted on the vehicle is equipped
with the necessary RDC electronics,
and will be also be monitored once the
tires have been mounted and the
system activated.<
RDC cannot alert you to severe
and sudden tire damage caused
by external factors.<
Have the tires changed by your
BMW center.
Your BMW center has been trained to
work with the RDC system and is
equipped with the necessary special
tools.<
System interferenceLocal devices using the same radio
frequency can interfere with the RDC.
The yellow indicator lamp will come on
during the malfunction.
The indicator lamp also comes on
>in the event of a system fault
>if a wheel is mounted without the
appropriate electronics
>if, in addition to the spare tire
*, addi-
tional wheels with RDC electronics
are on board.
Please contact your BMW center for
additional information.

Tire replacement Tire rotationTire ageThe date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 4100 means that the tire was
manufactured in week 41 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.
Spare tires over 6 years old should be
used only in case of emergency. A tire
in this condition should be replaced by
a new tire immediately, and should not
be mounted together with new tires.
Between the axlesThe tread wear patterns at the front end
differ from those at the rear Ð the actual
patterns will vary according to indi-
vidual driving conditions. In the inter-
ests of safety and maintaining optimal
handling characteristics, tire rotation is
not recommended.
If a proposed interaxle rotation of tires
is based on economic considerations,
one should consider whether the costs
for the rotation are likely to be recap-
tured by any increase in the service life
of the tires that might be realized. In
principle, interaxle rotation must be
performed in short intervals, with a
maximum of 3,000 miles (5,000 km).
Consult your BMW center for more
information.
Should you decide to rotate the tires, it
is essential to comply with the following:
Rotate tires on the same side only, since
braking characteristics and road grip
could otherwise be adversely affected.
Following rotation, the tire inflation
pressure should always be corrected.If different tire sizes are mounted
on the front and rear axles (refer to
page 130), the wheels may not be
rotated from one axle to the other.<
128n
Wheel and tire combinations The right choice Use only BMW-approved tires. Refer to
page 130.
Due to the high speeds this vehicle can
reach, the use of specific brands, spec-
ifications and sizes is mandatory.
Consult any BMW center for details.
Comply with local/national regulations.
The correct wheel-tire combina-
tion affects different systems such
as ABS, ATC and ASC+T/DSC. The
function of these systems is impaired if
improper wheel-tire combinations are
used.
For this reason, use only tires of the
same brand and tread pattern. In the
event of a flat tire, for example, remount
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.
The 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 187 mph (300 km/h)
ZR = above 150 mph (240 km/h) Example:
Nominal width
in mm
Aspect ratio in %
Radial tire ID code
Rim diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)
205/60 R
1591W
Winter tires and all-season 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 valve from dirt by using
screw-on valve stem caps. Dirt in the
valves frequently leads to slow leaks. Example:
Rim width
in inches
Code letter for
flange type
Symbol for full-drop

Changing a wheel Battery Driving with the space-saver
spare tireDrive cautiously and do not exceed a
speed of 45 mph (80 km/h).
Be aware that vehicle handling will be
altered. Slower brake response time,
longer braking distances and changed
steering characteristics may be antici-
pated when approaching limit condi-
tions.
The changes in handling characteristics
will be even more pronounced in
conjunction with winter tires.
Only one space-saver spare tire
may be mounted at one time.
Mount a wheel and tire with the same
size and specifications as the others
at the earliest possible opportunity.
Maintain correct tire pressures. Refer
to page 29.<
Battery locationThe battery is located at the right-rear
of the luggage compartment. Raise the
luggage compartment floor panel (refer
to page 41). Use a screwdriver or a coin
to loosen the two fasteners in the illus-
tration f-turn. Loosen the third fastener
in the upper-center side trim panel.
Remove the fasteners. In order to
remove the storage tray, slide the side
trim panel slightly upward.
Battery posts, terminals, and
related accessories contain lead
and lead compounds. Wash hands after
handling.<460de176
Charge conditionThe "Magic Eye
*" is a hydrometer that
allows you to read the charge condition
of the battery:
>Green: adequate charge.
>Black: not adequately charged. The
battery must be recharged. Please
contact your BMW center for addi-
tional information.
>Yellow: replace the battery.
The service life specified for the
battery can be achieved only if it is
always kept adequately charged. If the
vehicle is primarily used for stop-and-
go traffic, be sure to check the charge
state often.<
