used in your country (psi; kilopascal).
For vehicles with Tire Pressure Control 
(RDC): 
After correcting the tire inflation pres-
sure, reactivate the system. Refer to 
page 91.462de197
Check tire inflation pressures, 
including the space-saver spare 
tire, regularly, at least every two weeks 
and before beginning any extended 
driving. Otherwise, incorrect tire pres-
sure can lead to tire damage and acci-
dents.<

Tire inflation pressure Comply with tire approval 
specificationsThe inflation pressures in the table 
apply to tires from BMW-approved 
manufacturers. Your BMW center is 
familiar with these manufacturers. 
Higher pressures may be specified for 
tires made by other manufacturers. You 
will find a list of approved tires begin-
ning on page 137.
Your vehicle is equipped with tires that 
meet US and European standards. We 
recommend the exclusive use of tires 
approved by BMW.BMW Tires
All pressure specifications in 
the table are indicated in psi 
(kilopascal) for cold tires 
(cold = ambient temperature)

For all season tires, use the same tire inflation pressure as for summer tires.
BMW 325Ci: when using the tire 205/50 R 17 93 W extra load, the
inflation pressure increases by 3 psi (20 kilopascal). 
BMW 330Ci: when using the tire 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).

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 to stop the vehicle in a safe 
location. Avoid hard brake applications. 
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 flat tire. It does not have 
RDC electronics and is not monitored.<
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 RDC 
electronics. 
>if additional wheels with RDC elec-
tronics are on board.
Please contact your BMW center for 
additional information.

Information for your safetyThe factory-approved radial tires are 
matched to the vehicle and have been 
selected 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 signifi-
cantly influences the roadholding ability 
of your BMW.
Be sure to check the tire inflation 
pressure Ð including the space-
saver spare tire Ð on a regular basis, i.e. 
at least twice a month and before 
beginning a longer trip. Refer to 
page 28. If this is not done, incorrect 
tire pressures can cause driving insta-
bility and tire damage, ultimately 
resulting in an accident.<
Tire tread Ð tire damageInspect your tires frequently for tread 
wear, signs of damage and for foreign 
objects lodged in the tread. Check the 
tread depth. 
Tread depth should not be allowed to 
go 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 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
Do not drive on a deflated (flat) 
tire. A flat tire greatly impairs 
steering and braking response, and can 
lead to complete loss of control over 
the vehicle. 
Avoid overloading the vehicle so that 
the permitted load on the tires is not 
exceeded. Overloading can lead to 
overheating and increases the rate at 
which damage develops inside the 
tires. You could have a blowout as a 
result. 
Unusual vibrations encountered during 
normal vehicle operation can indicate 
tire failure or some other vehicle defect. 
This is also true for irregularities in the 
vehicle's handling characteristics, such 
as a pronounced tendency to pull to the 
left or right. Should this occur, respond 
by immediately reducing your speed. 
Proceed carefully to the nearest BMW 
center or professional tire center, or 
have the vehicle towed in to have it and 
its tires inspected. 
Tire damage (up to and including blow-
outs) can endanger the lives of both the 
vehicle occupants and other road 
users.<

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 41of 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, tire rotation must be 
performed at short intervals (maximum 
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 137), the wheels may not be 
rotated from one axle to the other.<

Changing a wheel 
Take these precautionary 
measures if you have either a flat 
tire or are changing the tire:
Stop the vehicle as far as possible from 
passing traffic. Park on a firm, flat 
surface. Switch on the hazard warning 
flashers. Turn the steering wheel to the 
straight-ahead position, remove the key 
and engage the steering lock. Shift into 
1st or reverse gear (selector lever in 
"Park" with automatic transmission) and 
engage the parking brake. 
All passengers should be outside the 
vehicle and well away from your imme-
diate working area (behind a guardrail, 
for instance). 
Set up a warning triangle
* or portable 
hazard warning on the roadside at an 
appropriate distance from the rear of 
the vehicle. Comply with all safety 
guidelines and regulations. 
Change the wheel only on a level, firm 
surface which is not slippery. Avoid 
jacking the vehicle on a soft or slippery 
support surface (snow, ice, loose 
gravel, etc.), as it could slide sideways. 
Position the jack on a firm support 
surface. 
Do not place wooden blocks or similar 
objects  under the jack. If this is done, 
the jack might not be able to reach its 
full support capacity because of the 
limited height. 
Do not lie under the vehicle or start the 
engine when the vehicle is supported 
by the jack. Failure to comply with this 
creates a risk of fatal injury.< 
Your BMW has a space-saver spare tire 
for temporary use to ensure your 
mobility. 
To remove the space-saver spare 
tire, take out the floor panel in the 
luggage compartment completely (refer 
to page 41).<
You will need the following:In order to avoid rattling noises later, 
note the position of the tools when you 
remove them and return them to their 
original position when you are through 
using them.
>Jack (1) 
Raise the floor panel in the luggage 
compartment (refer to page 41) and 
unclip the jack from where it is stored 
(arrow). 
After use, swing the crank back and 
clip into place.
>Wedge (2) 
Located behind the jack on the wall 
in the luggage compartment. Loosen 
the wing nut to remove it.46cde038
