Never exceed the maximum
speed laid down for the winter
tyres fitted to your car.
Lack of expert knowledge or incorrect
handling of tyres can cause damage
and lead to accidents.
All work on tyres should therefore be
carried out only by experts.
BMW Service will gladly place its spe-
cialised knowledge and facilities at your
disposal.

Tyre condition and tyre pressures
Below a tread depth of 4 mm (3/16 in),
winter tyres become noticeably less
suitable for winter driving conditions
and should therefore be replaced for
safety reasons.
Keep to the specified tyre pressures
and have the wheels and tyres rebal-
anced each time the wheels are
changed or new tyres fitted.
Snow chains*
Only certain snow chains have been
tested by BMW and determined and
approved as roadworthy. You can
obtain information on approved makes
from BMW Service. BMW recommends
using only these approved fine-link
snow chains. Fit snow chains to either
summer or winter tyres, but only to both
rear wheels.
325xi, 330xi, 330xd: only under
extreme circumstances – vehicle stuck
on one side or if a tyre is inaccessible –
is it permissible to fit a chain to one rear
wheel for a short time.
When fitting, comply with the manufac-
turer's instructions. When snow chains
are in use, do not exceed 50 km/h
(approx. 30 mph).
Snow chains cannot be fitted to tyres of
the following sizes:
> 225/50 R 16
> 225/45 R 17
> 245/40 R 17
> 255/35 R 18.
Do not initialise the Runflat Indica-
tor after fitting snow chains.
When driving with snow chains, it may
be advisable to switch off DSC tempo-
rarily, see page
