Wheel and tyre combinations
Choosing the correct tyres
Use only wheels and tyres
approved by BMW for your vehi-
cle, because even if the nominal sizes
are the same, manufacturing tolerances
and other factors could cause the tyres
to contact the bodywork and this, in
turn, could result in serious accidents. If
BMW has not approved the wheels and
tyres it cannot assess their suitability or
provide any guarantee of road safety.
<
For each size of tyre BMW tests certain
makes, and approves those that it certi-
fies as roadworthy. You can obtain
information on approved makes from
BMW Service. Always comply with
national regulations: some countries,
for example, require special entries in
the vehicle's registration papers.
The correct wheel and tyre combi-
nation has an effect on various
systems which could otherwise mal-
function, for example ABS, AGS,
ASC+T/DSC and ADB/ADB-X/DBC.
For this reason, only use tyres of the
same make and tread design and, for
example after a tyre failure, have the
approved combination of wheel and
tyre fitted to the car again as soon as
possible.

Tyre storage
Store wheels and tyres in a cool, dry
and preferably dark place when not in
use. Protect tyres against contamina-
tion from oil, grease and fuel.
Winter tyres
The correct tyres
BMW recommends you to fit winter
tyres (M+S radial-ply) if the car is used
for driving in wintery conditions.
Although there are tyres with an M+S
marking for use all the year round, and
their performance in winter is better
than that of summer tyres with H, V, W,
Y or ZR speed codes, they do not nor-
mally match the performance of winter
tyres.
In the interests of reliable directional
stability and steerability, fit winter tyres
of the same make and tread pattern to
all four road wheels.
Note the speed limit applicable to
these tyres
In Germany: a warning notice stating
the maximum permitted speed with
winter tyres fitted must be displayed in
the driver's field of view if the car is
capable of a speed higher than that
permitted for the winter tyres (please
check for similar local legislation). Tyre
dealers and BMW Service points can
supply these labels.
