Information for your safety It is not merely the tire's service life, but
also driving comfort and – to a great
extent – driving safety that depend on
the condition of the tires and the main-
tenance of the specified tire pressure. Checking inflation pressureOnly check tire inflation pressure when
the tires are cold. i.e. after driving a
maximum of 1.25 miles/2 km or when
the vehicle has been parked for at least
2 hours. When tires are warm, the tire
inflation pressure increases.
Regularly check the tire inflation
pressure and correct as needed,
including the spare tire: at least every
two weeks and before beginning a
longer trip. If this is not done, incorrect
tire pressures can cause driving insta-
bility and tire damage, ultimately result-
ing in an accident. Do not drive with a
depressurized, i.e. flat, tire. A flat tire
greatly impairs steering and braking
response, and can lead to complete
loss of control over the vehicle.<
After correcting the inflation pres-
sure(s), always reinitialize the Flat
Tire Monitor, refer to page102.<
Inflation pressure for original
equipment tiresYou will find tire inflation pressures on
the inside door pillar.Inflation pressure for other tire
sizesThe tire pressure table below gives all
of the tire pressure specifications for
the tire sizes indicated, with the ambi-
ent temperature.
In order to clearly identify the cor-
rect tire inflation pressure for your
tires, be sure to note the specifications
for the appropriate tire sizes.<530de225

Tire identification marksKnowledge of the labeling on the side
of the tire makes it easier to identify and
choose the right tires.Tire sizeSpeed code letter:
Q = up to 105 mph/160 km/h
T = up to 118 mph/190 km/h
H = up to 131 mph/210 km/h
V = up to 150 mph/240 km/h
W = up to 167 mph/270 km/hTire Identification Number Tires with DOT codes meet the guide-

DOT code:Tire age The manufacturer of your BMW recom-
mends that all tires, i.e. including the
spare wheel, be replaced regardless of
the actual wear after 6 years at the lat-
est.
The tire's date of manufacture is indi-
cated on the sidewall:
DOT... 3603 indicates that the tire was
manufactured in week 36 of 2003. Uniform Tire Quality Grading Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example: e.g.
Manufacturer's code
for tire brand
Tire size and tire model
Tire age
DOT xxxx xxx 3603
DOT Quality Grades Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must con-
form to Federal Safety Require-
ments in addition to these grades.< Tread wear The tread wear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course.
For example, a tire graded 150 would
wear one and one-half, 1γ, times as
well on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may
depart significantly from the norm due
to variations in driving habits, service
practices and differences in road char-
acteristics and climate.

Replacing wheels/tires
Have new wheels and tires
installed only by your BMW Sports
Activity Vehicle center or a tire special-
ist workshop that works according to
BMW guidelines with appropriately
trained personnel. If this work is not
carried out properly, there is a danger
of subsequent damage and related
safety hazards.<
Retreaded tires
BMW does not recommend the
use of retread tires, as otherwise
driving safety may be reduced. The rea-
son for this is that possible variations in
the design and aging – which could be
substantial – of the tire casing can
result in a limited service life.<
The right wheels and tires
BMW recommends that you use
only wheel and tire combinations
that BMW has tested and approved for
your particular vehicle. Variations in fac-
tors such as manufacturing tolerances
mean that even wheels and tires with
identical official size ratings could actu-
ally have different dimensions than the
approved units – these differences
could lead to body contact, and with it
the risk of severe accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.<
You can ask your BMW Sports Activity
Vehicle center for the correct wheel/tire
combination.
The correct wheel/tire combination also
affects various systems whose function
would otherwise be impaired, e.g. ABS,
DSC, xDrive.
To maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer. After a flat tire, always remem-
ber to have the original wheel and tire
combination remounted on the vehicle
as soon as possible.
Recommended tire sizes and makes:
For each tire size, certain tire makes
have been tested by BMW and classi-
fied and approved as safe. You can find
out about them at a specialized store,
preferably your BMW Sports Activity
Vehicle center. Follow any national reg-
ulations, e. g. listed in the vehicle docu-
ments.
The factory-approved radial ply tires are
matched to your vehicle and with
proper use, offer both optimal driving
safety and the desired driving comfort.
Special features of winter tires BMW recommends winter tires for use
in cold winter driving conditions.
Although all-season M+S tires provide
better winter traction than summer
tires, they generally fail to provide the
same levels of cold-weather perfor-
mance as winter tires.
When switching to winter tires, observe
the description under Tire condition,
page144, and Replacing wheels/tires.
Observing speed ratings:
Never exceed the maximum
speed for which the winter tires
are rated. Unprofessional attempts by
laymen to service tires can lead to dam-
age and accidents. Have this work per-
formed by skilled professionals only.
The technicians at your BMW Sports
Activity Vehicle center will be glad to
assist you with the required profes-
sional knowledge and specialized
equipment.<

Replacing wheels/tires Snow chains
*
Storage Store wheels or tires in a cool, dry
place, protecting them against light
whenever possible. Always protect tires
against all contact with oil, grease and
fuels.
Do not exceed the maximum tire infla-
tion pressure indicated on the side wall
of the tire.Only certain snow chains have been
tested by BMW and classified and
approved as safe. Consult your BMW
Sports Activity Vehicle center for
details. BMW recommends only using
these approved, narrow-link snow
chains. Use is only permitted in pairs on
the rear wheels with the following tire
sizes:
X5 4.8is: 255/55 R 18
All other models: 235/65 R 17
Observe the manufacturer's instruc-
tions when installing snow chains.
Do not exceed a maximum speed of
30 mph/50 km/h.
After mounting snow chains, do
not initialize the Flat Tire Monitor.
When you are driving with snow chains,
it can be beneficial to switch off DSC
briefly, refer to page96.<

Changing a wheel Vehicle battery 10. Screw in the remaining lug bolts.
Tighten all the bolts securely in a
diagonal pattern
11. Lower the jack and remove it from
beneath the vehicle
12. Tighten the lug bolts in a diagonal
pattern
13. Check and correct the tire inflation
pressure at the earliest opportunity.
After mounting the spare wheel or
correcting the inflation pressure,
reinitialize the Flat Tire Monitor,
refer to page102.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirt in
the valve stems frequently leads to slow
leaks.
The vehicle jack is designed for
changing wheels only. Do not
attempt to raise another vehicle model
with it or to raise any load of any kind.
To do so could cause accidents and
personal injury.
To ensure safety, always have the lug
bolts checked with a calibrated torque
wrench as soon as possible to ensure
that they are tightened to the specified
torque. The tightening torque is
101 ft-lb/140 Nm.<
Store the wheel and the tools in the
order opposite that for removal.
Before removing the support rod,
be sure that the tailgate is held
down firmly. If you fail to do so, it could
retract sharply upward and cause per-
sonal injury and vehicle damage.
After you remove the rod, close the tail-
gate carefully. Continue to hold it firmly
until it is completely closed.<
If light-alloy wheels other than Genuine
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced. Driving with spare wheel
Do not exceed a speed of
130 mph/210 km/h, otherwise tire
damage could lead to accidents.<
With certain wheel-and-tire com-
binations the size of the spare
wheel differs from that of the other
wheels. To restore the original state,
the normal wheel should be remounted
as soon as possible.<
Battery posts, terminals and
related accessories contain lead
and lead compounds. Wash hands after
handling.<
Battery care The battery is maintenance-free, that is,
the original electrolyte will normally last
for the service life of the battery under
moderate climatic conditions. Your
BMW Sports Activity Vehicle center will
be glad to advise in all matters con-
cerning the battery.Charging battery Only charge the battery in the vehicle
via the terminals in the engine compart-
ment with the engine off. For correct
connections, refer to Jump starting on
page171. Disposal
Following replacement, have old
batteries disposed of by your
BMW Sports Activity Vehicle center or
hand them in to a recycling center.
Maintain the battery in an upright posi-
tion for transport and storage. Always
restrain the battery to prevent it from
tipping over during transport.<
