REPAIR AFTER PUNCTURE OR FLAT RUNNING

Remove the tyre and the support (consulting the cor-
responding method).

With a rag, remove most of the gel present in the tyre
and the support.

Inspect the inside of the tyre to detect any sign of the 
following possible types of damage:

- chafing or overheating marks on the inner rubber

characteristic of prolonged running at an inadequa-
te pressure,

- detachment of rubber or plies,

- visible or deformed bead wires,

- damage to the bead laying bare the plies.

Inspect the support to detect any sign of the following 
possible types of damage:

- missing pieces;

- cracks in the partitions or the crown,

- visible blistering.

If the tyre is not damaged in any of the specified 
ways, it may be repaired by a PRP (tyre repair patch) 
on condition that the perforations or holes meet the 
following conditions:

- on the sidewalls, the perforation must be less than

3 mm, up to speed code T inclusive (codes H, V, W,
Y and Z with perforated sidewall must be replaced),

- in the crown region for perforations less than 6 mm

for all speed codes.

Refit the tyre and support (consult the corresponding
method).

Inflate the tyre. The pressure values given in the ma-
nuals and Technical Notes are values for a fully la-
den vehicle or for motorway travel.

The tyre inflation pressure must be checked when
cold.

WARNING

No repair can be carried out without removing the
tyre and support.

WHEELS AND TYRES

Run flat tyres: Specifications

WHEEL COMPOSITION

A wheel comprises four components:

- a tyre (A) (also known as the cover),

- a support (B),

- a wheel rim (C),

- a pressure detector (D) with built-in valve.

The tyre, the support and the wheel rim are asymme-
tric.

The pressure detector has a coloured marking determi-
ning the wheel's position on the vehicle.

The spare wheel (depending on equipment level) does
not have an active pressure detector.

It should be used only in case of emergency.

The wheels should be refitted in their respective posi-
tions on the vehicle after a servicing operation. Accor-
dingly, operations such as swapping wheels over are
strictly prohibited.
