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
