Wheels and tyres

Tyre condition, wheel condition

Drive over edges slowly and at right

angles if possible. Driving over sharp

edges can cause tyre and wheel

damage. Do not trap tyres on the kerb

when parking.
Regularly check the wheels for

damage. Seek the assistance of a

workshop in the event of damage or

unusual wear.

Winter tyres

Winter tyres improve driving safety at

temperatures below 7 °C and should

therefore be fitted on all wheels.
In accordance with country-specific

regulations, affix the speed sticker in

the driver's field of view.
4-door notchback

Tyre size 205/65 R16 is only suitable

as a winter tyre.

60 : cross-section ratio (tyre height

to tyre width), %

R

: belt type: Radial

RF : type: RunFlat

16 : wheel diameter, inches

95 : load index e.g. 95 is equivalent

to 690 kg

H

Directional tyres

Fit directional tyres such that they roll

in the direction of travel. The rolling

direction is indicated by a symbol

(e.g. an arrow) on the sidewall.

Tyre pressure

Check the pressure of cold tyres at

least every 14 days and before any

long journey. Do not forget the spare

wheel. This also applies to vehicles

with tyre pressure monitoring system.
