Run flat/Flat Run property (optional) You can drive about 50 kilometres on an empty tyre if the car is fully loaded. If the car is only carrying the driver, the transition drive can be up to 150 kilometres. Nokian Tyres recommends a maximum speed of 80 kilometres per hour. In very slippery conditions the speed should be kept down to about 50 km/h. Nokian Flat Run 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. When using Nokian Flat Run tyres we recommend the use of Extended Hump rims (EH2), which reduce the risk of bead unseating in case of loss of pressure.
