BMW 2009 X6 xDrive50i Owner's Manual

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

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.

<

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.

<

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.

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, 
Dynamic Performance Control in the BMW X6, 
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.

When mounting new tires or changing from 
summer to winter tires or vice versa, only use 
wheels with TPM electronics, otherwise the
