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 with respect to specific safety and operating information relating to the vehicle.
  • After low pressure warning is shown, the condition of the remaining tyres and the TPMS should be immediately checked 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 immediately replaced 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.
  • Pirelli reserve the right to modify the data contained in this communication without notice.
