What happens if a run flat tyre is punctured beyond repair?
If a run flat tyre sustains severe damage or has been driven on after a puncture, it cannot be repaired and must be replaced. The internal structure may have been compromised, even if the tyre appears undamaged from the outside. Continuing to drive on a damaged run flat can increase the risk of a blowout or handling issues.
How do I know if my run flat tyre is no longer usable?
A run flat tyre may be unusable if:
- It has been driven on without air pressure for too long – If it has exceeded the manufacturer’s recommended distance (typically 50 miles) or speed limit (50 mph), structural damage is likely.
- The puncture is outside the tread area – Sidewall damage or large cuts make the tyre unsafe to repair.
- It has visible internal damage – If inspected and found to have internal weakening or structural failure, it must be replaced.
- Manufacturer restrictions – Some brands prohibit repairs altogether, making any punctured run flat tyre unfit for use.
