Winter tyres
The handling of your vehicle will be significantly improved when driving on
wintry roads and at temperatures below 7 °C if you fit winter tyres.
Summer tyres do not offer the same grip on ice and snow at a temperature
below 7 °C because of their construction (width, rubber blend, tread
pattern). This particularly applies to vehicles which are equipped with low-
profile tyres or high-speed tyres (code index H or V on wall of tyre).
Winter tyres must be mounted on all four wheels to obtain the best
handling characteristics.
You must only fit those types of winter tyre which are approved for your
vehicle. The permissible sizes of winter tyres are stated in your vehicle
documents. Approvals may differ because of national legislation.
Please remember that the tyres should be inflated to 20 kPa (0.2 bar)
more than is the case for summer tyres ⇒ page 264, fig. 199.
Winter tyres no longer offer the same winter performance once the tyre
tread has worn down to a depth of about 4 mm.
Ageing also causes winter tyres to lose most of their winter performance
properties - even in cases where the remaining tread depth is still clearly
more than 4 mm.
Speed restrictions apply to winter tyres as well as to summer tyres
⇒ page 266, ⇒ .
You can fit winter tyres of a lower speed category to your vehicle provided
that you also do not drive faster than the permissible maximum speed for
such tyres, even if the possible maximum speed of your vehicle is higher.
The corresponding tyre category can damage the tyres when exceeding
the permissible maximum speed.
Please pay attention to the notes if you decide to fit winter tyres
⇒ page 263.
You can also fit so-called “all-weather tyres” instead of winter tyres.
Please contact your specialist garage if there are any points which are not
clear who will be able to provide you with information regarding the
maximum speed for your tyres.
WARNING
You must on no account drive your car at more than the permis-
sible maximum speed for your winter tyres - risk of an accident
resulting from tyre damage and loss of control over your car.
For the sake of the environment
Fit your summer tyres on again in good time since summer tyres offer you
better grip and handling on roads which are free of snow and ice as well
as ar temperatures below 7 °C - the braking distance is shorter, there is
less tyre noise, tyre wear is reduced and fuel consumption is reduced.
Note
Please observe the various differing legal requirements regarding tyres.
Unidirectional tyres*
The direction of rotation of the tyres is marked by arrows on the wall of
the tyre. This indicates the direction of rotation of the tyre, and it is essen-
tial that the tyres are fitted on to run in this direction. Only then are the
tyres able to provide the optimal properties in terms of grip, low noise,
wear-and-tear and aquaplaning.
Should it be necessary to fit on a spare wheel in exceptional cases with a
tyre not dedicated to the running direction or in opposite running direction,
please adopt a cautious style of driving as the tyre is no longer able to
provide optimal grip and handling in such a situation. This particularly
