Wheel and tire combinations The right choice
Use only wheels and tires
approved by BMW for the corre-
sponding vehicle model, as otherwise
the tires may make contact with the
body as the result of tolerances despite
the same nominal size being used,
resulting in serious accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.<
BMW tests certain tire brands for each
tire size, classifies them as road-safe
and approves them. Consult your
BMW Sports Activity Vehicle center for
more information. Observe any regula-
tions applicable in the country of use,
e.g. requiring entry in the vehicle docu-
ments.
The correct wheel and tire combi-
nation affects different systems
such as ABS, ATC and DSC. The func-
tion of these systems is impaired if
improper wheel and tire combinations
are used.
For this reason, use only tires of the
same brand and tread pattern on the
vehicle and, for example, restore the
approved wheel and tire combination
following a flat tire as soon as
possible.<
The use of rims and lug bolts that
do not meet the specifications of
the original factory-installed equipment
will affect the safe operation of your
vehicle and may cause an accident and
personal injury.
Never mix tires of different design, such
as steel-belted radials with radial bias
belted or bias-ply tires, etc. Mixing tire
types will adversely affect roadholding
and can lead to loss of vehicle
control.<
Storage Store wheels or tires in a cool, dry
place, protecting them against light
whenever possible. Protect the tires
against contact with oil, grease and
fuel.

Winter tires Snow chains
*
Choosing the right tire BMW recommends winter tires Ð M+S
radial tires Ð for operation under
inclement winter driving conditions.
While so-called all-season tires with
M+S designation provide better winter
traction than summer tires with the load
ratings H, V, W, Y and ZR, they gener-
ally do not achieve the performance of
winter tires.
In the interests of safe tracking and
steering response, install radial tires
made by the same manufacturer and
with the same tread configuration on all
four wheels if you elect to mount winter
tires.
Do not exceed specified
maximum speeds
Never exceed the maximum speed
for which the tires are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Your BMW Sports
Activity Vehicle center will be glad to
assist you with both their expertise and
the proper equipment for your vehicle.<
Tire condition, tire pressureWinter tires display a perceptible loss in
their ability to cope with winter driving
conditions once the tread wears to
below 0.16 in/4 mm, and should thus
be replaced.
Comply with the specified tire inflation
pressures Ñ and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.
Only certain snow chains have been
tested by BMW and classified and
approved as safe. Consult your BMW
Sports Activity Vehicle center for
details. The use of narrow-link BMW
snow chains is approved only in pairs
on the rear wheels and only with the
following tire sizes.
BMW X5 4.6is: 255/55 R18
All other models: 235/65 R 17.
Comply with all manufacturer's safety
precautions when mounting the chains.
Do not exceed a maximum speed of
30 mph/50 km/h.

Changing a wheel9. Position the spare wheel. Secure
the wheel by turning at least two
lug bolts into opposite bolt holes
10. Screw in the remaining lug bolts.
Tighten all the bolts securely
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 tire inflation pres-
sure, reactivate the system, refer to
page 97.
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 continued safety, have the
tightness of the lug bolts checked with
a calibrated lug wrench Ð torque speci-
fication: 101 lb-ft/140 Nm Ð at the
earliest opportunity.<
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 original
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
With certain wheel-and-tire com-
binations the size of the spare
wheel differs from that of the other
wheels. The spare wheel is equivalent
to these in all speed and load ranges.
However, to restore the original state,
the normal wheel should be remounted
as soon as possible.
When the spare wheel is mounted, the
maximum speed rating is 130 mph/
210 km/h.<
