Wheel and tyre combinations

Choosing the correct tyres

BMW recommends using only
wheels and tyres approved by

BMW for your vehicle, because even if
the nominal sizes are the same, manu-
facturing 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 can-
not 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 or from the tyre-fitting
specialist. Always comply with national
regulations: some countries, for exam-
ple, require special entries in the vehi-
cle's registration papers.

The correct wheel and tyre combi-
nation has an effect on various

systems which could otherwise mal-
function, for example ABS, DSC and
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 if the car is used for driving in win-
tery 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, they do not match the perform-
ance 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

If the car is capable of a speed higher
than that permitted for the winter tyres,
local legislation may require you to affix
a warning label in the driver's field of
vision, stating the maximum permitted
speed with winter tyres fitted. Tyre
dealers and BMW Service points can
supply these labels.
