Tyres

WARNING
Incidents which occur when driving, such as striking the kerb, may damage the tyres and wheel rims, and could also lead to misalignment of the front or rear axle geometry. In this case, have the condition of these checked by an approved dealer.
The tyres are the only contact between the vehicle and the road, so it is essential to keep them in good condition.
You must make sure that your tyres con- form to local road traffic regulations.

Maintaining the tyres

The tyres must be in good condition and the tread form must have sufficient depth; tyres approved by our Technical Department have wear warning strips 1 which are indicators moulded into the tread at several points.
When the tyre tread has been worn to the level of the wear indicators, they become visible 2: it is then necessary to replace your tyres because the tread rubber is 1.6 mm deep at most, resulting in poor road-holding on wet roads.
An overloaded vehicle, long journeys by motorway, particularly in very hot weather, or continual driving on poorly surfaced minor roads will lead to more rapid tyre wear and affect safety.

Changing wheels around

This practice is not recommended.

Tyre pressures

WARNING
Incorrect tyre pressures lead to abnormal tyre wear and unusually hot running. These are factors which may seriously affect safety and lead to:
  • poor road holding;
  • the risk of blow-outs or of throwing a tread.
The pressure depends on the load and the speed of use. Adjust the pressure according to the conditions of use (refer to the label affixed to the edge of the driver's door).
Adhere to the tyre pressures (including the emergency spare wheel). The tyre pressures should be checked at least once a month and additionally before any long journey (refer to the label affixed to the edge of the driver's door TYRE PRESSURE).
Pressures should be checked when the tyres are cold. Ignore higher pressures which may be reached in hot weather or after driving at high speed.
If tyre pressures measurement cannot be made while the tyres are cold, the normal pressures must be increased by 0.2 to 0.3 bar (or 3 PSI).
Never deflate a hot tyre.

Dual wheel versions

WARNING
Please be aware that a poorly tightened or missing valve cap can make the tyres less airtight and may lead to pressure loss.
Always use valve caps identical to the originals and screw them down fully.
To inflate the outer wheel, it is recommended that the inflation tube is passed between the two wheels.

Vehicle fitted with a tyre pressure loss warning system

In the case of under-inflation (puncture, flat tyre, etc.) the warning light appears on the instrument panel TYRE PRESSURE LOSS WARNING

Fitting new tyres

WARNING
For your safety and to comply with the law.
When they need to be replaced, only tyres of the same make, size, type and profile should be used on a single axle.
They must either have a load capacity and speed rating at least equal to those of the original tyres or conform to those recommended by an authorised dealer.
Failure to heed these instructions could endanger your safety and affect your vehicle's roadworthiness.
Risk of loss of control of the vehicle.

Use in winter

Chains

WARNING
Chains may only be fitted to tyres of the same size as those originally fitted to your vehicle.
Only certain chains can be fitted to tyres. Consult an approved dealer.
Chains must not be fitted to tyres which are larger than those originally fitted to the vehicle.

Front wheel drive versions

For safety reasons, fitting snow chains to the rear axle is strictly forbidden.

Rear wheel drive versions

For safety reasons, only fit chains on the rear axle.
Note: for rear wheel drive, dual wheel versions, fit chains on the outer rear wheels.

"Snow" or "Winter" tyres

We would recommend that these be fitted to all four wheels to ensure that your vehicle retains maximum grip.
Note: be aware that these tyres may sometimes have:
  • a direction for driving;
  • a maximum speed index which may be lower than the maximum speed of your vehicle.

Studded tyres

This type of equipment may only be used for a limited period and as laid down by local legislation.
It is necessary to observe the speed specified by current legislation.
These tyres must, as a minimum, be fitted to the two wheels on the front axle for front wheel drive versions and all the rear wheels for rear wheel drive versions.
Tip
In all cases, we would recommend that you contact an approved Dealer who will be able to advise you on the choice of equipment which is most suitable for your vehicle.
