PERFORMANCE, SAFETY, PEACE OF MIND

Run Flat tyres mean safety. They provide greater control of your car in emergency conditions and allow you to continue driving safely even during a rapid loss of inflation pressure.

With Run Flat, you will retain mobility in the event of a puncture. So, if your tyre is punctured, even in pouring rain, the Pirelli Self-Supporting Run Flat means you don't have to bother with the spare. Instead, you can continue driving for a limited period.

To ensure maximum safety during an emergency situation, the Run Flat tyre must maintain certain speed and distance parameters (80km/h for 80km or 50mph for 50 miles). Due to these restrictions, it's imperative that motorists be notified when a loss in tyre pressure occurs, and therefore the vehicle must be equipped with a TPMS (Tyre Pressure Monitoring System) to detect and signal tyre pressure changes.

OPERATING REQUIREMENT

Run Flat tyres have been developed based on the specifications of the vehicles on which they are mounted. Accordingly, Run Flat tyres may only be mounted on vehicles specifically manufactured to accommodate Run Flat tyres.

Run Flat tyres must be mounted in conjunction with a functional Tyre Pressure Monitoring System (TPMS). The mounting of tyres and installation of the TPMS should be carried out by a specialised dealer.

Pirelli certifies that after pressure loss, Run Flat tyres can continue to run for 80km (50 miles) at a maximum speed of 80km/h (50 mph). Always refer to the vehicle owner's manual for specific safety and operating information relating to the vehicle.

After the low pressure warning is shown, the condition of the remaining tyres and the TPMS should be checked immediately by a specialised dealer.

A tyre should always be changed and not repaired after a loss of pressure, as it is not always possible to establish the time and conditions under which the tyre has been used with insufficient inflation pressure.

Damaged Run Flat tyres, or Run Flat tyres that have experienced a loss of pressure should be replaced immediately with another Run Flat tyre of identical size and service description (Load Index and Speed Code). Pirelli recommends that a tyre of a different type, or which contains a different load index or speed code, should never be mounted on the same vehicle.

After a loss of pressure, the rims should be inspected to ensure they haven't been damaged. Damaged or deformed rims should always be replaced prior to mounting a new Run Flat tyre. Pirelli recommends the use of Extended Hump rims (EH2), which reduce the risk of bead unseating in case of loss of pressure.
