Not every puncture requires a full tyre replacement. In many cases, a qualified technician can repair the puncture safely and cost-effectively. Knowing the difference can save you money — but making the wrong call can put you at serious risk.
When a Puncture Can Be Repaired
A tyre can be repaired if the puncture is caused by a nail or similar object, it is located in the central three-quarters of the tread, and the hole is no larger than 6mm in diameter. The tyre must also have no secondary damage. British Standard BSAU159 governs what is and isn't a safe repair — any reputable fitter will follow it.
When You Need a Replacement
Replacement is the only safe option if the puncture is in the tyre sidewall, shoulder, or close to the edge of the tread, if the tyre has been driven on while flat (even briefly), if there is secondary cracking or bulging, or if the hole is too large. Never patch a sidewall puncture — the structural integrity cannot be restored.
Key Takeaways
- Do not drive on a flat tyre to reach a garage — call us instead
- Sidewall damage is always non-repairable, regardless of size
- A repaired tyre should be fitted to the rear axle, not front
- Always ask your fitter to confirm the repair follows BS AU159
