Component Term
Run-Flat Tyres
Tyres with reinforced sidewalls that can drive for a limited distance after a puncture.
Deep Dive
Run-Flats (RFT) allow you to drive ~80km at 80km/h with zero air pressure. They are standard on most modern BMWs and Mercedes. However, they are stiffer, heavier, and more expensive to replace than standard tyres.
