winter tires BMW X3 3.0I 2007 E83 Owner's Manual

Wheels and tires
94
Temperature
The temperature grades are A, B, and C, A
being highest, and represent the tire’s resis-
tance to the generation of heat and its ability to
dissipate heat when tested under controlled
conditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature can
lead to sudden tire failure. The grade C corre-
sponds to a level of performance that all pas-
senger car 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 sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not fall below 0.12 in/
3 mm. At tread depths below 0.12 in/3 mm,
there is an increased risk of high-speed hydro-
planing, even when only small amounts of water
are present on the road surface.
Winter tires display a noticeable loss in their
ability to cope with cold-weather driving condi-
tions once the tread wears to below 0.16 in/
4 mm. To ensure continued safety you should
always have such tires replaced.Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the tire tread
has worn down to the wear indicators, then the
legally permissible tread depth limit of 0.063 in/
1.6 mm has been reached.
Wheel/tire damage
Please note that low-profile tires, make
wheels, tires and suspension parts more
susceptible to road hazard and consequential
damages.<
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. The same
applies to any other abnormal road behavior,
such as pulling severely to the right or left.
In these cases, reduce speed immedi-
ately and have wheels and tires checked
immediately. Drive carefully to the nearest
BMW Sports Activity Vehicle Center or tire spe-
cialist. Have the vehicle towed to one of these
locations if necessary.
Tire damage can pose a potentially lethal safety
hazard for the vehicle's occupants and other
road users alike.<
New wheels and tires
Have new wheels and tires installed only
by your BMW Sports Activity Vehicle
Center or a tire shop that works according to
BMW repair procedures with correspondingly
trained personnel. If this work is not carried out
properly, there is a danger of subsequent dam-

age and related safety hazards. Make sure that
the new wheels are balanced.<
Retreaded tires
BMW does not recommend the use of
retreaded tires; otherwise, driving safety
may be reduced. The causes for this include the
possibly different tire casing structures and the
often wide variations in their age, which can
result in a limited service life.<
Correct 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 ask your BMW Sports Activity Vehicle
Center for the correct wheel-and-tire combina-
tion.
The correct wheel-and-tire combination 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. After tire
damage, always remember to have the original
wheel and tire combination remounted on the
vehicle as soon as possible.
Wheels equipped with electronics for
TPM Tire Pressure Monitor
When installing new tires or when changing
from summer tires to winter tires or vice versa,
only use wheels equipped with TPM electron-
ics; otherwise, the Tire Pressure Monitor can-
not detect a flat tire, refer to page54. Your
BMW Sports Activity Vehicle Center will be
happy to advise you in this regard.
Recommended tire brands
BMW recommends particular tire brands for
each tire size. You will recognize them by the
clearly visible BMW identification on the tire
sidewall.
With proper use, these tires meet the highest
standards for safety and handling characteris-
tics.
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires do provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated.<
Storage
Store wheels or tires in a cool, dry place, pro-
tecting them from light whenever possible. Pro-
tect the tires from contact with oil, grease and
fuel. Do not exceed the maximum tire inflation
pressure indicated on the side wall of the tire.
Changing wheels from one axle to
another
BMW does not recommend changing the front
wheels to the back or vice versa as this can
impair handling characteristics.

Protect valve stems with valve stem
seal caps from dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*, refer to
pages53, 54.
Do not initialize the Flat Tire Monitor
when driving with a compact wheel.<
5.Replace the defective 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.
Mounting the compact wheel can change the
driving characteristics. For example, it can
reduce tracking stability during braking, extend
braking distances, and alter self-steering char-
acteristics in the limit range. With winter tires,
these characteristics are more pronounced.
Only one compact wheel may be
mounted. You should re-equip with
wheels and tires of the original size as soon as
possible.<
Vehicle battery
Maintenance
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 Sports Activity Vehicle Center
will be happy to advise you on all questions con-
cerning the battery.
Warning lamp
The warning lamp lights up. The battery
is no longer being charged. The alterna-
tor V-belt is defective or there is a mal-
function in the charge current circuit of the
alternator. Have the system checked immedi-
ately.Do not continue driving if the V-belt is
defective. The engine could be damaged
due to overheating.
Moreover, an increased amount of force is
required for steering if there is a sharp drop in
the onboard supply voltage.<
Charging battery
Charge the battery in the vehicle only when the
engine has been switched off. For connections,
refer to Jump starting on page114.
Disposal
Have old batteries disposed of following
replacement at your BMW Sports Activity
Vehicle Center or bring them to a collection
point. Maintain the battery in an upright position
for transport and storage. Always secure the
battery to prevent it from tipping over during
transport.<
Power failure
After a temporary power supply interruption,
some equipment is subject to limited use and
must be reinitialized. Individual settings are also
lost and must be updated again:
>Panorama glass sunroof
It may be only possible to raise the sunroof.
The system must be initialized, refer to
page24.
>Power windows
The pinch protection system must be reini-
tialized, refer to page23.
>Seat and mirror memory
The positions must be stored again, refer to
page30.
>Time
Must be set again, refer to page46.
