and altered natural steering characteristics.
If unusual vibrations occur while the vehicle
is being driven, this can indicate final failure
of the damaged tire. Reduce speed and
stop as soon as possible. Do not continue
driving. Contact your BMW center.
<
New wheels and tires
Only have new wheels and tires
mounted by a specialist. If this work is
not carried out properly, there is a danger
of subsequent damage and related safety
hazards.
<
You can find out the right wheel-tire combi-
nation from your BMW center.
Have the wheel and tire assemblies bal-
anced every time either a wheel or a tire is
replaced.
The correct combination of wheels and
tires is another vital factor in ensuring reli-
able operation of various vehicle systems
such as ABS and DSC.
BMW does not recommend that you
use retreaded tires, since driving
safety may be impaired. Possible variations
in the design and the age – which could be
substantial – of the carcasses can lead to
unusually rapid wear.
<
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 manufacturing 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 accidents. If non-
approved wheels and tires are used, BMW
cannot evaluate their suitability, and there-
fore cannot be held liable for driving
safety.
<
To maintain good handling and vehicle
response, use only tires of a single tread
configuration from a single manufacturer.
After flat tire, always remember to have the
specified wheel and tire combination
remounted on the vehicle as soon as pos-
sible.
Recommended tire sizes and makes
BMW tests certain tire brands for each tire
size, classifies them as road-safe and
approves them. You can find out about
these at specialized dealers or at your
BMW center. Observe any country-specific
regulations, e.g. on making a correspond-
ing entry in the vehicle documents.
The factory-mounted tires have been spe-
cially selected to provide optimized perfor-
mance when installed on your vehicle; if
properly cared for, they will provide a com-
bination of safety and excellent ride com-
fort.
Run-flat tires
If your BMW is equipped with run-flat tires,
refer to page
170 , only use these tires, as in
the event of a breakdown there is no spare
wheel available.
For safety reasons, BMW recom-
mends that you do not have damaged
run-flat tires repaired; they should be
replaced.

Special characteristics 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 performance as winter tires.
Run-flat tires
If your BMW is equipped with run-flat tires,
refer to page
170 , when mounting new
tires or converting from summer to winter
tires, or vice versa, use only run-flat tires,
as in the case of a flat tire, no spare wheel
is available. Your BMW center will be glad
to advise you.
