PUNCTURE REPAIR
A puncture always seems to happen at the worst possible time. Whether you’re commuting, doing the school run, or heading off on a long journey, a flat tyre can quickly disrupt your plans.
If your tyre is losing pressure, it’s important to have it checked as soon as possible. A professional puncture repair can often save your tyre and get you safely back on the road without the need for a replacement. From sharp objects in the road to valve or rim issues, there are several reasons why a tyre may deflate and not all are immediately visible.
At Eden Tyres & Servicing, our technicians carry out every tyre puncture repair in line with British Standard BSAU159. This ensures each repair meets strict guidelines on the size, location, and number of repairs allowed, using approved materials for a safe and long-lasting result.
Repairing a punctured tyre isn’t always as simple as it seems, but with the right expertise, it can be a reliable and cost-effective solution.
When a Tyre Can’t Be Safely Repaired
Not every puncture can be repaired safely. Before any tyre puncture repair is carried out, the tyre must be carefully inspected to make sure it’s suitable for repair and safe to return to the road.
Repairs are only possible if the damage meets strict safety guidelines, including British Standard BSAU159. If any of the following issues are found, a puncture repair should not be attempted:
- Sidewall damage (this area cannot be safely repaired)
- Bulging or visible deformities in the tyre
- Exposed cords within the tyre structure
- Damage to the bead (where the tyre seals to the wheel)
- Secondary damage caused by the object that punctured the tyre
- Previous repairs that are faulty or not up to standard
- Signs of ageing or deterioration in the rubber
- Tread depth below the legal limit (1.6mm across the central ¾ of the tyre, around the entire circumference)
- A puncture larger than 6mm
If there’s ever any doubt, it’s always safer not to repair the tyre. In these cases, replacing the tyre is the best way to ensure your safety on the road.
Puncture Location
As well as the type of damage, the location of the puncture is just as important when deciding if a repair is possible.
British Standard BSAU159 sets out clear guidelines on where a tyre puncture repair can be safely carried out. Repairs are only permitted within the central ¾ of the tyre tread – known as the “minor repair area” – where the structure of the tyre is strongest.
If the puncture is outside of this area, particularly close to the sidewall, it cannot be safely repaired. This is because the sidewall flexes as you drive, meaning any repair in this area would be unreliable and at risk of failure.
If your tyre isn’t suitable for repair due to its condition or the puncture location, the safest option is always a replacement – ensuring you can get back on the road with confidence.
Run-Flat Tyre Repairs
Run-flat tyres are designed with reinforced sidewalls, allowing them to stay operational even after a puncture. This means you can continue driving for a limited distance, giving you time to reach a garage safely rather than stopping immediately at the roadside.
They’re commonly fitted to vehicles such as BMW and MINI models, as well as other premium brands.
While run-flat tyres offer clear safety benefits, assessing them for a tyre puncture repair requires extra care. Due to their reinforced construction, it can be difficult to determine whether internal damage has occurred or how long the tyre has been driven on while deflated – both of which are critical factors in deciding if a repair is safe.
In some cases, a puncture repair on a run-flat tyre may be possible. However, repairs will only be carried out if the tyre meets strict safety standards. If there is any uncertainty, replacement is always the safer option.
Your safety is the priority – even if that means replacing the tyre rather than repairing it.
Tyre Puncture Repair FAQ's
A tyre can lose pressure for several reasons, not just a puncture. Common causes include a nail or screw in the tread, a leaking valve, corrosion around the wheel rim, or damage to the tyre itself.
If you keep needing to top up your tyre pressure, or one tyre looks lower than the others, you may have a slow puncture. It’s best to get it checked as soon as possible to avoid further damage.
No — not all punctures can be repaired safely. It depends on the size of the puncture, where it is on the tyre, and the overall condition of the tyre.
In general, a puncture must be 6mm or smaller to be considered for repair. Anything larger than this cannot usually be repaired safely.
No — punctures near or in the sidewall cannot be safely repaired. Repairs are only allowed within the central ¾ of the tyre tread, in line with British Standard guidelines.
A tyre should not be repaired if it has sidewall damage, bulging, exposed cords, bead damage, faulty previous repairs, ageing rubber, illegal tread depth, or secondary internal damage caused by the puncture.
Sometimes, but only if they pass a full safety inspection. Because run-flat tyres are designed to keep working after a puncture, it can be harder to tell whether internal damage has occurred.
If the puncture is safe to repair, repair is usually the most cost-effective option. If the tyre does not meet safety standards, replacement is the only safe choice.
A puncture repair usually takes around 30 to 45 minutes, depending on the tyre and the type of damage.
No – continuing to drive on a punctured tyre can cause further damage and may make the tyre unsafe to repair. It’s always best to have it checked as soon as possible.
