TYRES

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 conform 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 that 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 no more than 1.6 mm deep, resulting in poor roadholding 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.

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.

Tyre pressures

Adhere to the tyre pressures. 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.

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;

- risk of bursting or tread separation.

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).

Pressures should be checked when the tyres are cold; ignore higher pressures which may be reached in hot weather or following a fast journey.

If tyre pressures cannot be checked when 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.

Please be aware that a poorly tightened or missing valve cap can make the tyres less airtight and lead to pressure loss.

Always use valve caps identical to those fitted originally and tighten them fully.

Vehicle fitted with a tyre pressure monitoring system

In the event of under-inflation (punctures, under-inflation, etc.), the warning light appears on the instrument panel TYRE PRESSURE MONITORING SYSTEM.

Changing wheels around

This practice is not recommended.

For safety reasons, it is forbidden to exchange the 17” front wheels (tyres and/or rims) with the rear wheels.

Fitting new tyres

For your safety, please respect the speed limit.

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 a speed capacity at least equal to the original tyres, or correspond to those recommended by your 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

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

Chains cannot be fitted to tyres which are larger than those originally fitted to the vehicle.

Snow or Winter tyres

We would recommend that these be fitted to all four wheels to ensure that your vehicle retains maximum adhesion.

Warning: These tyres sometimes have a specific direction of rotation and a maximum speed index which may be lower than the maximum speed of your vehicle.

17” wheels cannot be fitted with chains.

If you wish to use special equipment, consult an approved dealer.

Chains may only be fitted to tyres of the same size as those originally fitted to your vehicle.

Chains may be fitted, provided that they are specific chains. We would advise you to consult an approved dealer.

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, at a minimum, be fitted to the two front wheels.

NB:

The use of snow tyres, winter tyres or studded tyres significantly reduces the vehicle range.

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.
