When a Puncture Can Usually Be Repaired
Most straightforward punctures can be safely repaired if they meet the following conditions:
Central tread location
Within the middle 75% of the tyre's width.
Small hole size
Typically under 6mm in diameter.
Not driven while flat
No significant distance covered under-inflated.
No sidewall damage
Surrounding tread and sidewall undamaged.
When a Tyre Should Be Replaced Instead
Sidewall damage – Cannot be safely repaired due to the lack of reinforced structure.
Large or irregular punctures – Larger than 6mm or jagged holes generally can't be reliably sealed.
Driven while flat – Internal damage may not be visible even if the puncture itself looks repairable.
Multiple or close punctures – Can compromise overall structural integrity.
Low remaining tread – Often more sensible to replace than repair a tyre nearing the end of its life anyway.
Why a Proper Inspection Matters
Punctures are not always as simple as they look from the outside. A professional inspection, including checking the inside of the tyre once removed from the wheel, is the only reliable way to confirm whether a repair is genuinely safe.

FAQs
Can a sidewall puncture be repaired?
No, sidewall damage cannot be safely repaired and the tyre needs to be replaced.
Is a plug from the outside a proper repair?
No, a proper repair requires removing the tyre to inspect and patch it from the inside, not just plugging from outside.
How big can a puncture be and still be repairable?
Generally under 6mm in diameter and located within the central tread area, though a professional inspection is always needed to confirm.
