228 Wheels and tyres
Winter tyres lose their effectiveness when the tread is worn down to a depth
of 4 mm.
The speed rating code ⇒ p age 226, New tyres and wheels determines the
following speed limits for winter tyres: ⇒
Q max. 160 km/h
S max. 180 km/h
T max. 190 km/h
H max. 210 km/h
In some countries, vehicles which can exceed the speed rating of the fitted
tyre must have an appropriate sticker in the driver's field of view. These
stickers are available from your Technical Service. The legal requirements of
each country must be followed.
Do not have winter tyres fitted for unnecessarily long periods. Vehicles with
summer tyres handle better when the roads are free of snow and ice.
If you have a flat tyre, please refer to the notes on the spare wheel
⇒ p age 226, New tyres and wheels.
WARNING
The maximum speed for the winter tyres must not be exceeded. Other-
wise, this could lead to damage and risk of accident.
For the sake of the environment
Fit your summer tyres again as soon as possible. They are quieter, do not
wear so quickly and reduce fuel consumption.
Snow chains
Snow chains are only permitted on front wheels and only for tyres
195/65R15 and 205/55R16. These tyres may only be fitted with fine-pitch
link chains which do not protrude more than 15 mm ⇒ p age 260.
Other tyres may use fine-pitch links which do not protrude more than 9 mm,
including tension device.
Remove wheel hub covers and trim rings before fitting snow chains. For
safety reasons, cover caps, available at any Technical Service, must then be
fitted over the wheel bolts.
All-wheel drive: Where snow chains are compulsory on certain roads, this
normally also applies to cars with all-wheel drive. Snow chains may only be
fitted to the front wheels (also on vehicles with all-wheel drive).
WARNING
Snow chains should be correctly tightened in accordance with the manu-
facturer's instructions. This will prevent the chains coming into contact
with the wheel housing.
CAUTION
Remove the snow chains to drive on roads without snow. Otherwise they
will impair handling, damage the tyres and wear out very quickly.
Note
● In some countries, the maximum permitted speed with snow chains is

50 km/h (31 mph). The legal requirements of each country must be fol-
lowed.
● We recommend that you ask your Technical Service for information
about appropriate wheel, tyre and snow chain size.
