Snow Chains - BMW 320i Owner's Handbook Manual

When properly used, these tyres meet the high-
est standards in terms of safety and handling
characteristics.
Run-flat tyres
When fitting new tyres or changing over from
summer to winter tyres and vice versa, fit run-
flat tyres for your own safety. In the event of a
flat, moreover, no spare wheel is available.
BMW Service will be glad to advise you on this.
For safety reasons, BMW recommends
that damaged run-flat tyres be renewed
rather than repaired.<
Special characteristics of winter tyres
BMW recommends you to fit winter tyres if the
car is used for driving in wintry conditions.
Although all-season tyres with an M+S marking
have better winter characteristics than summer
tyres, they do not normally match the perform-
ance of winter tyres.
Note the speed limit applicable to these
tyres
Always comply with the speed limit for the
winter tyres fitted to your car; failure to do
so could result in tyre damage and
If the car is capable of speeds higher than that
permitted for the winter tyres, a label stating the
maximum permitted speed for the tyres fitted
must be displayed in your field of view. Special-
ist tyre dealers and BMW Service can supply
these labels.
Tyre storage
Store wheels and tyres in a cool, dry and prefer-
ably dark place when not in use. Protect tyres
against contamination from oil, grease and fuel.

tested by BMW, classified as safe for use and
