Tire inflation pressure The inflation pressures are indicated on 
a sticker attached to the B-pillar behind 
the driver's door (visible with door 
open).Check tire pressuresAll pressure specifications are stated in 
psi (kilopascal) with cold tires (cold = 
ambient temperature). Refer to the next 
page as well.
For trailer towing, the inflation pressure 
for heavier loads always applies.
For vehicles with RDC (Tire Pressure 
Control)
*:
After a correction of the tire inflation 
pressure, reactivate the system. Refer 
to page 82.

Check tire inflation pressures reg-
ularly – at least every two weeks 
and before beginning a longer trip. In-
correct tire pressure can otherwise lead 
to tire damage and accidents.
Also check the inflation pressure of the 
space-saver tire or spare tire
*. Inflate 
the spare tire to the highest inflation 
specified for your vehicle.<
Comply with tire approval 
specificationsThe inflation pressures in the table apply 
to tires from BMW-approved manufac-
turers. Your BMW center is familiar with 
these pressures. Higher pressures may 
be specified for tires from other manu-
facturers. You will find a list of approved 
tires beginning on page 117.

Tire Pressure Control (RDC)

Flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with 
a red lamp. In addition, there is an 
acoustical warning signal.
If this occurs, reduce vehicle speed im-
mediately and stop the vehicle in a save 
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 case 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 also be monitored once the 
tires have been mounted and the sys-
tem activated.<
The RDC cannot alert you to 
severe and sudden tire damage 
caused by external factors.<
Have the tires changed by your 
authorized BMW center.
Your authorized BMW center has been 
trained to work with the RDC system 
and is equipped with the necessary 
special tools.<
System interferenceThe RDC can be subjected to interfer-
ence locally by outside equipment or 
devices which use the same radio fre-
quency.
The indicator lamp will come on with 
a yellow lamp 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 authorized BMW 
center for additional information.

Information for your safetyThe factory-approved radial tires are 
matched to the car and have been se-
lected to provide optimum safety and 
driving comfort on your car. 
It is not merely the tire's service life, but 
also driving comfort and – above all 
else – 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 pressure regu-
larly — including the space-saver 
and/or the spare tire — at least twice a 
month and before beginning a longer 
road trip. Incorrect tire pressure can 
otherwise lead to tire damage and acci-
dents.<
Tire tread – Tire damageInspect your tires frequently for tread 
wear, signs of damage and for foreign 
objects lodged in the tread. Check the 
tread depth. 
The tread depth should not be any shal-
lower than 0.12 in (3 mm).
Otherwise there is an increased risk of 
aquaplaning, even at relatively moder-
ate speeds and with only small amounts 
of water on the road.
We recommend that you always replace 
the tires once the tread wears to 0.12 in 
(3 mm). If you continue to use the tires, 
wear indicators appear in the tread at 
0.063 in (1.6 mm).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. 
The ultimate result can assume the form 
of a sudden air loss.
Unusual vibrations encountered during 
normal vehicle operation can indicate 
tire failure or some other vehicle defect, 
as can variations in normal vehicle 
response, such as a pronounced ten-
dency to pull to the left or right. Should 
this occur, respond by immediately 
reducing your speed and carefully pro-
ceeding to the nearest BMW center or 
professional tire center, or having 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.<

114n
To maintain good handling and vehicle 
response, use only tires of a single 
tread configuration from a single manu-
facturer. BMW tests and approves 
wheel/tire combinations. Refer to 
page 117.
Do not use retreaded tires, since 
driving safety may be impaired by 
their use. This due to the possible varia-
tions in casing structures and, in some 
cases, to their extreme age, that can 
lead to a decrease in their durability.<
Tire ageThe date on which the tire was manu-
factured is indicated by the code on the 
sidewall:
DOT ... 129 indicates that the tire was 
manufactured in Week 12 of 1999.
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. Such 
a tire should be replaced by a new tire 
immediately, and should not be fitted 
together with new tires.
Between the axlesThe tread wear patterns at the front end 
differ from those at the rear – the actual 
patterns will vary according to individ-
ual driving conditions. In the interests of 
safety and maintaining optimal handling 
characteristics, tire rotation is not rec-
ommended.
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 which might be realized.
In principle, interaxle rotation should be 
performed in short intervals, with a 
maximum of 3,000 miles (5,000 km). 
Consult your authorized 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, correct the tire infla-
tion pressure.
If different tire sizes are mounted 
on the front and rear axles (refer to 
page 117), the wheels may not be ro-
tated from one axle to the other.<

Changing tires 
Take these precautionary mea-
sures if you have either a flat tire 
or are changing the tire:
Park the vehicle as far from the flow of 
traffic as possible and on firm ground. 
Switch on the hazard flashers. Turn the 
steering wheel to the straight-ahead 
position, remove the key and engage 
the steering lock. Shift into 1st or re-
verse (selector lever in "Park" with auto-
matic) and engage the parking brake.
All passengers should be outside the 
car and well away from your immediate 
working area (behind the guardrail, for 
instance).
If a warning triangle or portable hazard 
warning lamp is available, set it up on 
the roadside at an appropriate distance 
from the rear of the vehicle. Comply 
with all safety guidelines and regula-
tions.
Change the wheel only on a level, firm 
surface that is not slippery. Avoid jack-
ing the car on a soft or slippery support 
surface (snow, ice, loose gravel, etc.), 
as it could slide sideways.
Ensure that the jack is positioned on a 
solid support surface.
Do not place wooden blocks or similar 
objects  under the jack. If this 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 – risk of fatal injury.<
