Flat tire
The red warning lamp in the
instrument cluster lights up to
warn of pressure loss and tire
failure. This visual alert is accompanied
by an acoustic warning signal. Reduce
your speed immediately, and steer and
brake gently as you bring the vehicle to
a stop.
To reset the warning lamp: after replac-
ing the flat tire you will need to reset the
red warning lamp manually. Maintain
pressure on the Flat Tire Monitor button
until the warning lamp goes out. Then
reinitialize the system.
The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors.
The system also does not detect the
gradual and minor loss of pressure that
all tires display over extended periods
of time.<
Check tire inflation pressures on a
regular basis, correcting them as
necessary, refer to page 25.
The system may respond to operation
on slippery or snow-covered road sur-
faces with false warnings or delays in
detecting actual pressure loss.
Performance-oriented driving – slip at
the drive wheels, high rates of lateral
acceleration – can also increase the
time that the Flat Tire Monitor requires
to detect a flat tire.<
System malfunctionsThe yellow indicator lamp in the instru-
ment cluster lights up and remains on
until the problem is corrected.
Please refer the problem to your BMW
center.

117 Wheels and tires
Tire inflation pressureInformation for your safetyThe factory-approved tires are matched
to your vehicle and have been selected
to provide optimum safety and driving
comfort when used properly.
It is not merely the tire's service life, but
also driving comfort and – above all else
– driving safety that depend on the con-
dition of the tires and the maintenance
of the specified tire inflation pressure.
Incorrect tire inflation pressure is a fre-
quent cause of tire damage. It also sig-
nificantly influences the roadholding
ability of your BMW.
Be sure to check the tire inflation
pressure, including the space-
saver spare tire or the spare tire, on a
regular basis, at least twice a month
and before every extended journey,
refer to page 25. If this is not done,
incorrect tire pressures can cause driv-
ing instability and tire damage, ulti-
mately resulting in an accident.<
Tire conditionTire tread – 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 1/8 in / 3 mm, even though
the legally specified minimum tread
depth is 1/16 in / 1.6 mm.
Below 1/8 in / 3 mm tread depth, there
is a great risk of hydroplaning, even at
relatively moderate speeds and with
only small amounts of water on the
road. Tread wear indicators – see arrow
– are embedded in the base of the tire's
tread. Their locations are indicated by
the letters TWI – Tread Wear Indicator –
at various points on the tire's shoulder.
When the tread reaches a depth of
1/16 in / 1.6 mm, these indicators
appear and signal that the tires have
worn to the minimum legal level.
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 leads to over-
heating and causes damage to the
inside of the tires.
The ultimate result can assume the
form of a sudden air loss.
Unusual vibrations encountered during
normal vehicle operation can indicate a
damaged tire or some other vehicle
malfunction. This type of problem can
be caused by contact with curbs, etc.
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.

tires must meet under the Federal
Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels
of performance on the laboratory test
wheel than the minimum required by
law.
The temperature grade for this tire
is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible tire failure. applicable on the tire sidewall between

BMW advises against using
retreaded tires, since driving
safety may be impaired. This is due to
the possible variations in casing struc-
tures and, in some cases, to their
extreme age, which 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... 3502 indicates that the tire was
manufactured in week 35 of the year
2002.
BMW recommends the replacement of
all tires – including the spare tire* –
when the tires are no more than 6 years
old, even if a tire life of 10 years is pos-
sible.Run Flat tires*Run Flat tires consist of self-supporting
tires and special rims. The tire rein-
forcement ensures that the tire retains
some residual safety in the event of
pressure drop and driving remains pos-
sible to a restricted degree. The vehicle
is equipped with a Tire Pressure Moni-
tor (TPM) or Flat Tire Monitor, which
indicate a flat tire. For additional infor-
mation on the Tire Pressure Monitor
(TPM) or Flat Tire Monitor, refer to
page 85 or 86.
Run Flat tires are only possible in
conjunction with the Tire Pres-
sure Monitor (TPM) or Flat Tire Moni-
tor.<

Tire condition, tire pressureAt tread depths below approx. 3/16 in /
4 mm, winter tires display a perceptible
decrease in their ability to cope with
winter driving conditions, and should be
replaced in the interest of safety.
Comply with the specified tire inflation
pressures — and be sure to have the
wheel and tire assembly balanced
every time you change a tire or wheel.Snow chains*Only certain snow chains have been
tested by BMW and determined and
approved as roadworthy. Consult any
BMW center for details. BMW recom-
mends using only these approved fine-
link snow chains. Use them in pairs on
either summer or winter tires, but only
on both rear wheels.
BMW 325xi: in an extreme emergency –
for instance, with the vehicle stuck on
one side, or when obstructions make it
impossible to reach one tire – a chain
may also be mounted on just one tire
for the limited period needed to resolve
the problem.
Comply with all manufacturer's safety
precautions when mounting the chains.
Do not exceed a speed of 30 mph /
50 km/h when unsing snow chains.You cannot mount snow chains on the
following tires:
225/50 R 16
225/45 R 17
245/40 R 17
225/40 R 18

13. Wheels with full wheel covers*:
place the wheel cover with the
valve opening – see arrow – over
the valve. Use both hands to press
the cover securely onto the rim
14. Check and correct the tire inflation
pressure at the earliest opportunity.
Vehicles with Tire Pressure Monitor
(TPM)/Flat Tire Monitor: after
mounting the spare tire or correct-
ing the inflation pressure, reinitial-
ize the system, refer to page 85
or 86.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirty
valve stems frequently lead to slow
pressure loss.
Do not attempt to install the full
wheel cover on the space-saver
spare tire, since this could damage the
cover.<
The vehicle jack is designed for
changing wheels only. Do not
attempt to raise another vehicle model
with it or to raise any other type of load.
To do so could cause accidents and
personal injury.
To ensure continued safety, have the
tightness of the torque bolts checked
with a calibrated lug wrench – torque
specification: 88.5 lb ft/120 Nm – at the
earliest opportunity.<
When storing a wheel in the spare tire
recess, take care to avoid bending the
threaded rod.
If the original BMW light-alloy wheels
have been replaced with other light-
alloy wheels, different lug bolts may be
required.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.
Driving with the space-saver
spare tireDrive cautiously. Do not exceed a
speed of 50 mph / 80 km/h.
Be aware that vehicle handling may be
altered. Anticipate, e.g., reduced track-
ing during braking, longer braking dis-
tances, and changed steering charac-
teristics when approaching limit
conditions. These handling characteris-
tics will be even more pronounced if
winter tires are mounted.
Only one space-saver spare tire
may be mounted at one time.
Mount a wheel and tire of the original
size at the earliest possible opportu-
nity. For certain wheel/tire combina-
tions, the size of the spare tire will
differ from that of the remaining tires.
The spare tire is fully functional at all
loads and speeds. However, the spare
tire should be replaced at the earliest
possible opportunity in order to achieve
the original operating conditions.<

Run Flat tires*Run Flat tires are labeled on the side-
wall with a circular symbol containing
the letters RSC. Run Flat tires consist of
self-supporting tires and special rims.
The tire reinforcement ensures that the
tire retains some residual safety in the
event of pressure drop and driving
remains possible to a restricted degree.
The vehicle is equipped with a Tire
Pressure Monitor (TPM) or Flat Tire
Monitor, which indicate a flat tire.
Because the sides of Run Flat
tires are reinforced, a drop in infla-
tion pressure usually cannot be
detected from the outside.<
Flat tireIf there is a tire failure, the red warning
lamp symbol lights up. This visual alert
is accompanied by an acoustic warning
signal.
Additional information on the Tire Pres-
sure Monitor (TPM) or Flat Tire Monitor
is found beginning on page 85.
Reduce vehicle speed carefully to
under 50 mph / 80 km/h, avoiding hard
brake applications and steering maneu-
vers.
If the defective wheel is not immedi-
ately recognizable on the outside,
check the tire pressure at all four
wheels.
Have Run Flat tires replaced by
your BMW center. In the interest
of safety, Run Flat tires should not be
repaired. Your BMW center has the
information needed for working with
Run Flat tires and is equipped with the
necessary special tools.<
If appropriate, please consult your
BMW center to reequip your vehi-
cle from summer to winter tires – or vice
versa.<
Driving with a damaged tireRun Flat tires allow you to continue
driving to a restricted degree at a maxi-
mum speed of 50 mph / 80 km/h
depending on the cargo load and the
extent of tire damage. You can deter-
mine the distance you may continue
driving on the basis of the following val-
ues:
>Tire inflation pressure of
0 psi/0 kilopascal (kPa):
approx. 100 miles/150 km
>Tire inflation pressure of approx.
7-15 psi/50-100 kPa:
approx. 300 miles/500 km
>Tire inflation pressure greater than
15 psi/100 kPa:
approx. 600 miles/1,000 km.
Drive cautiously. Do not exceed a
speed of 50 mph / 80 km/h. Be
aware that vehicle handling will be
altered when there is a loss in inflation
pressure. Anticipate, e.g., reduced
tracking during braking, longer braking
distances and changed steering char-
acteristics.<
