Wheels and tyres
Unusual vibration or the car pulling to one side may indicate that one of the
tyres is damaged. Reduce speed immediately and stop if you suspect that
damage may have occurred! Check the tyres for damage (blisters, cracks,
etc.). If no external damage is visible, drive slowly and carefully to the near-
est Official Service and have the vehicle inspected.
Handling wheels and tyres

wheels around
Changing wheels around
If the wear is visibly greater on the front tyres, they should be exchanged for
the rear tyres as shown in the diagram ⇒ Fig. 125. All the tyres will then last
for about the same time.
To ensure that the wear is equal on all tyres and maintain their optimum
useful life, they should be changed around every 10 000 km (6000 miles).
Storing tyres
Mark tyres when you remove them to indicate the direction of rotation. This
ensures you will be able to install them correctly when you replace them.
When removed, the wheels and/or tyres should be stored in a cool, dry and
preferably dark location. Store tyres in a vertical position if they are not fit-
ted on wheel rims. Replacing tyres and wheels
All four wheels must be fitted only with tyres of the same type, size and the
same tread pattern.
The correct tyre/wheel combinations specified for your vehicle are listed in
its registration documentation.
Understanding the tyre designations makes it easier to choose the correct
tyres. The tyre designation is marked on the sidewall. For example.
