Verification and diagnosis of tyres to be repaired
Before making a repair, the tyre systematically undergoes a careful inspection by a
professional. A tyre that has been running flat or insufficiently inflated may have suffered
irreversible damage and only an exhaustive verification of the inside of the tyre can
diagnose whether or not the tyre can be reused.
It is therefore essential to remove the tyre to properly ascertain its actual condition and
the type of repair to be made. Tyres showing signs of the following cannot be repaired and
MUST be taken off the road:
Exposed or deformed bead wire
Heating or separation of internal plies
Damage by oil, grease or corrosive materials
Plucking or mottling of the interior rubber
Cracking of the rubber due to ageing of the tyre
