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.

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 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 a flat
tire, always 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 page

. 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.
