Technical requirements for run-flat tyres
As a general rule, vehicles should only be fitted with run-flat tyres or SSR tyres if intended by the vehicle manufacturer. In addition, the use of run-flat tyres requires vehicles to have a tyre pressure monitoring system (TPMS). This is necessary because drivers using SSR tyres will not immediately notice a puncture or pressure loss. When using run-flat tyres, it is also recommended to have an electronic stability programme (ESP) on board the vehicle.
