146 n 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,
page
144 , 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.
