Run-flat tires

You will recognize run-flat tires by the circular
symbol containing the letters RSC on the side
of the tire.
Run-flat tires consist of partially self-contained
tires and special rims. The sidewall reinforce-
ment ensures that the tire retains some residual
safety in the event of pressure drop and driving
remains possible to a restricted degree.
To continue driving with a damaged tire:

With Flat Tire Monitor, refer to Indication of
a flat tire page

With Tire Pressure Monitor, refer to Mes-
sage with low tire inflation pressure page

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 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

When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. Your
BMW Sports Activity Vehicle Center will be
happy to advise you.

For safety reasons, BMW recommends
that you do not have damaged run-flat

tires repaired; they should be replaced. Other-
wise it is not possible to rule out occurrences of
consequential damage.

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.

When changing to larger wheels and tires,
it may be necessary to make changes to

the wheel-well trim piece, as otherwise road
users could be endangered or the vehicle could
be damaged. Only have this work carried out by
a BMW Sports Activity Vehicle Center or a
workshop that works in accordance with BMW
guidelines and uses appropriately trained per-
sonnel.

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 other-
wise be impaired, e.g. ABS, DSC, xDrive or Flat
Tire Monitor.
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.
