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 self-contained tires and
special rims. The sidewall reinforcement
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

Only have new wheels and tires mounted
by a BMW center or a repair shop that

works in accordance with BMW guidelines and
uses appropriately trained personnel. If this
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
hazards. Make sure that the new wheels are bal-
anced.

Retreaded tires

BMW does not recommend the use of
retreaded tires; otherwise, driving safety

may be reduced. Potentially substantial varia-
tions in the design and the age of the carcasses
can result in a reduced 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 find out the right wheel-tire combina-
tion from your BMW center.
The right wheel-and-tire combination is
another vital factor in ensuring reliable opera-
tion of various vehicle systems such as ABS
and DSC.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. After a tire is
damaged, always remember to have the original
wheel and tire combination remounted on the
vehicle as soon as possible.

Wheels with electronics for
TPM Tire Pressure Monitor

When mounting new tires or converting from
summer to winter tires or vice versa, only use
wheels with TPM electronics, otherwise the
Tire Pressure Monitor cannot detect a flat tire,
refer to page

. Your BMW center will be

happy to advise you on this subject.
