Some tyres have been designed for specific needs. They have specific features that may raise the question of their reparability. There are three types:
Acoustic tyres :
They contain a special foam that reduces the noise of the tyre when it is running. This type of tyre can be repaired in the same way as a standard tyre.
Self-seal tyres :
These tyres are self-repairing only in the tread area. In the event of a puncture, a self-obstructing rubber plugs the hole. This type of tyre can be repaired in the same way as a standard tyre. If self-seal tyres are available in the dimensions specified by the manufacturer for your vehicle, you can choose to fit them.
Runflat tyres:
These tyres make it possible to continue driving to the nearest garage after a puncture without damaging the inside of the tyre. At Michelin, runflat tyres are marked ZP (Zero Pressure) and/or EMT (Extended Mobility Tyres). Runflat tyres can be repaired once.
Please note that runflat tyres are mounted on a specific rim adapted to a certain category of vehicle. They cannot be mounted on a normal rim.
