But they can give a stiff and bumpy ride, they’re more expensive than conventional tyres and they can’t be repaired meaning you will have to replace them after a puncture.Run-flat tires are not repairable. After significant tire pressure loss, they are only designed to stabilize the vehicle for 50 miles. No puncture repair of these tires is possible. If they are patched up, more likely they will puncture again due to loss of rigidity and uneven wear.If a run flat tyre sustains severe damage or has been driven on after a puncture, it cannot be repaired and must be replaced.
