Run flat tires should only be fitted to vehicles that come with Run flat tires as the original tire. Any vehicle that has Run flat tires requires a TPMS (tire pressure monitoring system) so the driver can determine if there is a puncture. RFTs don’t actually go flat in the traditional sense. They have significantly reinforced tire walls which can safely carry the weight of the car for a short period even after a total loss of air pressure.
