Snow Chains - BMW 730i Owner's Handbook Manual

Recommended makes of tyre
Certain makes of tyre are recommended by
BMW for each tyre size. You can recognise
these by the clearly visible BMW designation on
the sidewall of the tyre.
When properly used, these tyres meet the high-
est standards in terms of safety and handling
characteristics.
Run-flat tyres
When mounting new tyres or replacing summer
with winter tyres or conversely, use tyres with
run-flat properties for your own safety. In the
event of a puncture there is moreover no spare
wheel at your disposal. Your BMW Service will
be pleased to advise.
In the interests of safety, BMW recom-
mends that damaged run-flat tyres be
replaced 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
Do not exceed the maximum speed laid
down for the winter tyres fitted to your
car, otherwise the tyres could become dam-
aged and this could result in an

permitted for the winter tyres, a label stating the

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.
Interchanging front and rear wheels
BMW advises against interchanging the front
and rear wheels, as this could impair their han-
dling characteristics.

Snow chains*

Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. BMW Service is able to provide
the details of these makes. Such chains may be
used only as a pair, with winter tyres fitted at the
rear. When fitting, comply with the snow chain
manufacturer's instructions. When driving with
chains, do not exceed a speed of 50 km/h,
approx. 30 mph.
