Michelin ZP

Michelin ZP is Michelin's self supporting run flat tyre technology

This Self Supporting Tyre (SST) technology should only be used on vehicles originally designed for this type of tyre. Do not fit ZP tyres on vehicles not designed for this technology.
Michelin ZP tyres have reinforced sidewalls which support the vehicle weight in the event of pressure loss. ZP technology is available in the following ranges; Michelin Primacy HP, Michelin Pilot Sport and Michelin Pilot Alpin.

Michelin ZP or ZP SR technology is used by BMW, Mercedes, Cadillac and Dodge.
Where relevant, the vehicle handbook will contain useful information on self supporting tyres.

Provides improved safety compared to standard tyres in the event of a puncture:

Safety: Control of the car can be maintained with a greatly reduced risk of the tyre coming off the wheel even at zero pressure. Hazardous roadside wheel changes can be avoided.
Mobility: Gives the possibility to continue your journey with a flat tyre for up to 50 miles* at speeds up to 50 mph.

The Michelin ZP self-supporting tyre :

Innovative sidewall: More robust sidewalls, reinforced with a special rubber compound to carry the vehicle weight at low or even zero pressure.
Innovative bead area: Helps a deflated tyre stay securely seated on the wheel.
A pressure sensor linked to the dashboard warns the motorist in the event of pressure loss.

Markings:

Michelin ZP or ZP SR tyres are identified by the ZP (Zero Pressure) or ZP SR logos on the sidewall.

In the event of a puncture:

Motorists can continue their journey, which they would be unable to do with a standard tyre. There is no need to stop, simply reduce speeds and continue driving for up to 50 miles* at up to 50 mph to reach a tyre distributor to arrange a replacement or repair. If more than one tyre is deflated, it is recommended to stop driving immediately. Vehicle handling may be affected when driving a deflated Michelin ZP in snow, and account must be taken of this.

* up to 20 miles for the Michelin ZP SR tyre.

Fitment rules:

Michelin advises that a vehicle should be equipped with 4 Michelin ZP or 4 Michelin ZP SR tyres. Michelin ZP tyres must always be fitted in pairs on an individual axle. Michelin ZP and ZP SR tyres must not be mixed on a vehicle. Run flat tyres and non run flat tyres must not be mixed on a vehicle.

Michelin ZP or ZP SR tyres must only be fitted on wheels designed for vehicles equipped with self-supporting tyres.

Repair:

A Michelin ZP may be repaired once and once only by a tyre professional following the normal rules and procedures for the inspection, preparation and repair of standard tyres.
ZP tyres which carry sidewall markings indicating that repairs should not be carried out are still considered non-repairable.
