2008 BMW 525XI TOURING tires

Wheels and tires
230
Retreaded tires
BMW does not recommend that you use
retreaded tires, as driving safety may be
impaired. The causes for this include the possi-
bly different tire casing structures and the often
wide variations in their age, which 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 factors such as manufac-
turing tolerances mean that even wheels and
tires with identical official size ratings could
actually have different dimensions than the
approved units – these differences could lead to
body contact, and with it the risk of severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot be held liable for driving
safety.<
You can inquire about the right wheel/tire com-
bination at your BMW center.
The correct wheel/tire combination also affects
various systems whose function would other-
wise be impaired, e.g. ABS, DSC or xDrive.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. Following
tire damage, have the original wheel and tire
combination remounted on the vehicle as soon
as possible.
Wheels with electronics for
TPM Tire Pressure Monitor
When mounting new tires or converting from
summer to winter tires or vice versa, only use
wheels with TPM electronics, otherwise the
Tire Pressure Monitor cannot detect a flat tire,
refer to page96. Your BMW center will be
happy to advise you on this subject.
Recommended tire brands
Certain tire makes are recommended by BMW
depending on the tire size. You can recognize
these from the clearly visible BMW marking on
the tire sidewall.
When used properly, these tires comply with
the most demanding standards for safety and
vehicle response.
Run-flat tires
When mounting new tires, or changing from
summer to winter tires or vice versa, use run-flat
tires for your own safety. In addition, no spare
tire is available in case of a flat tire. Your BMW
center will be glad to advise you.
Special characteristics 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 performance as
winter tires.
Paying attention to speed
Always observe the maximum permissi-
ble speed for the winter tires, otherwise
t i re d a m a g e m a y o c cu r , w h ic h c a n re s u l t i n a c c i-
dents.<
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible. Always
protect tires against all contact with oil, grease
and fuels. Do not exceed the maximum tire
inflation pressure indicated on the side wall of
the tire.

Rotating wheels between axles
BMW does not recommend moving the front
wheels to the rear or vice versa, as otherwise
the handling characteristics may be impaired.
With tires of different makes and types
* such a
change is not permissible.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Consult your BMW center for more infor-
mation.
Use is only permissible in pairs on the rear
wheels.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with the chains mounted.
After mounting snow chains, do not ini-
tialize the Flat Tire Monitor, otherwise
incorrect displays can occur.
When driving with snow chains, it may be prac-
tical to briefly activate DTC, refer to page91.<

What you will need
To avoid rattling noises later on, note the posi-
tions of the tools before removing them, then
return them to their initial positions after com-
pleting work.
1Chock
*
2Vehicle jack*
3Lug wrench*
The tools are located in the mount under the
floor mat or floor panel flap.
1.Lift up floor mat or floor panel flap and cover
located beneath it.
2.Take out the required tools.
3.After using the tools, return them to the
storage space.
With run-flat tires, no tools are provided
for wheel changes. They can be pur-
chased as accessories at your BMW center.<
Sports Wagon: removing and installing
floor panel flap of storage area package
1.Unhook the roll-up cover at the rear.
2.Raise the floor panel flap.
3.Unhook the two catch straps at the top.4.Unlock the gas spring strut, refer to arrow,
and remove.
5.Fold over the floor panel flap toward the
front to release it and remove.
6.Open the front floor panel flap.
7.Swing up the spare tire cover and hook the
hooks into the upper frame of the tailgate
opening.
8.Take out the cross support upward.
When installing the floor panel flap, proceed in
the reverse order and press down the hinge
covers.

3.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems with valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Initialize the Flat Tire Monitor, refer to
page94, or reset the Tire Pressure Monitor,
refer to page96.
5.Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
The driving characteristics change, for example
reduced track stability on braking, extended
braking distance, and altered self-steering
characteristics in the limit range. In conjunction
with winter tires, these characteristics are more
pronounced.
Only one compact wheel may be
mounted. Restore the wheels and tires to
their original size as quickly as possible. Failure
to do so is a safety risk.<
Vehicle battery
Battery care
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW center will be glad to advise in
all matters concerning the battery.
Charging battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine switched off. Connections, refer to
Jump starting on page254.
Disposal
Have old batteries disposed of by your
BMW center or hand them in to a recy-
cling center. Maintain the battery in an upright
position for transport and storage. Always
restrain the battery to prevent it from tipping
over during transport.<
Power failure
Following a temporary power failure, e.g. due to
a discharged battery, the use of some equip-
ment will be restricted, requiring its reinitializa-
tion. In the same way, individual settings are lost
and must be updated again:
>Seat, mirror and steering wheel memory
The positions must be stored again, refer to
page48.
>Time and date
Must be updated again, refer to page86.
>Radio
Radio stations must be stored again, refer
to page174.
>Navigation system
You must wait until the system becomes
functional again, refer to page142.
>Glass roof, electric
It may only be possible to raise the glass
roof. The system must be initialized, refer to
page42.
>Panorama glass roof
It may only be possible to raise the glass
roof. The system must be reinitialized, refer
to page44.
>Active steering
The system is deactivated and must be
reinitialized, refer to page98. Until then,
larger steering wheel movements are
required.
>Power windows
The pinch prevention system for the power
windows must be reinitialized, refer to
page40.
Talk to your BMW center before placing
the stored vehicle back in service.
