Key takeaways
- Do not pull the nail out — while it stays in place it can plug the hole and slow or stop the air loss.
- A nail in the central tread is often repairable to British Standard BS AU 159; a nail in the sidewall or shoulder is not.
- If the tyre is holding pressure, you may be able to drive carefully to safety; if it is going flat, do not drive on it.
- Mark the nail with chalk or tape so a fitter can find it quickly, and check the pressure before any journey.
- A proper plug-and-patch repair from inside the tyre is the only durable fix — sealant is a temporary measure only.
Finding a nail or screw in your tyre is one of the most common things UK drivers face, and the instinct is often to yank it straight out. That is usually the wrong move. Whether the tyre can be saved depends on where the nail is and how long you act sensibly. This guide explains what to do, what not to do, and when to call for help.
Should you pull a nail out of your tyre?
No, do not pull the nail out. While it stays in place, the nail partly seals the hole it made, so the tyre may lose air slowly or barely at all. Pull it out and you can turn a manageable slow puncture into a fast deflation, leaving you stranded. Leave it in until a professional can repair the tyre properly.
The one exception is that you should still inspect and monitor the tyre — but inspecting does not mean removing the object. Note where it is, check the pressure, and plan your next step.
Can a nail in a tyre be repaired?
Often, yes — if the nail is in the central three-quarters of the tread and the puncture is small. A proper repair removes the tyre from the wheel, plugs and patches it from the inside, and is done to British Standard BS AU 159. A nail in the sidewall or the shoulder cannot be repaired and means a new tyre.
| Where the nail is | Repairable? |
|---|---|
| Central tread (the main grooved area) | Usually yes, if the hole is small |
| Shoulder (edge of the tread) | No — outside the repairable zone |
| Sidewall | No — needs replacement |
| Within 6mm of a previous repair | No — needs replacement |
For the full rules on which punctures qualify, see our guide on whether a punctured tyre can be repaired. If the object is in the sidewall, our sidewall damage guide explains why it is not fixable.
How to check if the tyre is losing air
Check the pressure with a gauge against the figure on your door-pillar sticker or in the handbook. If the tyre is at or near the right pressure and holding, you likely have a slow puncture you can manage briefly. If it is well down and dropping, treat it as a flat and do not drive on it.
- Find the nail and mark its position with chalk, tape or a coin so it is easy to relocate.
- Check the pressure on that tyre and compare with the others and the recommended figure.
- Listen and feel near the nail for escaping air — a faint hiss means an active leak.
- Re-check the pressure after 10–15 minutes to see how fast it is dropping.
- Decide: hold steady means manage it; dropping fast means stop and call for help.
Is it safe to drive with a nail in the tyre?
It can be safe to drive a short distance to a safe place or a fitter if the tyre is holding pressure and the nail is in the tread — but only carefully and at low speed. If the tyre is losing air, soft or flat, it is not safe, and driving on it risks both a blowout and ruining a tyre that could otherwise have been repaired.
For more on the risks, our guide on whether it is safe to drive on a flat tyre sets out what under-inflation does to the tyre and the car.
Signs you have picked up a nail without seeing it
You will not always spot the nail straight away. Often the first sign is a slow loss of pressure or a TPMS warning light, long before you find the culprit. If a single tyre keeps needing a top-up while the others hold steady, a slow puncture from an embedded object is one of the most likely causes.
- One tyre repeatedly reads low when you check the pressures.
- The TPMS warning light comes on, then sometimes clears after re-inflation.
- A faint hiss when the car is quiet, or a small flat spot where it has been parked.
- The car pulls slightly or feels soft on one corner at low speed.
If this sounds familiar, our guide to slow puncture causes and fixes helps you track it down, and the TPMS warning light explained covers what the dashboard light is telling you.
What to do at the roadside versus at home
Your next step depends on where you are. At home or in a car park, you have time to check the pressure, mark the nail and decide calmly. At the roadside, especially on a fast road, safety comes first — get to a safe place before doing anything, and on a motorway get behind the barrier and call for help rather than inspecting in a live lane.
| Where you are | Sensible first move |
|---|---|
| At home or work | Check pressure, mark the nail, book a repair |
| Quiet road or car park | Pull over fully, inspect, decide whether to drive on |
| Busy A-road | Reach a safe spot first, then assess; avoid roadside work in traffic |
| Motorway | Get behind the barrier and call for help — do not inspect in a lane |
Why sealant is not a real fix
A tyre repair kit or sealant can get you home in an emergency, but it is a temporary measure, not a repair. It coats the inside of the tyre, can make a proper plug-and-patch repair harder or impossible afterwards, and many sealants are not compatible with TPMS pressure sensors and can clog or damage them. Use it to escape danger, then get a proper repair.
If you do carry one, read our tyre repair kit guide first so you know its limits before you need it.
Getting the nail dealt with properly
The durable fix is a professional repair or, where the nail is outside the repairable area, a replacement. Rather than drive on a compromised tyre to a garage, our puncture repair service comes to your home, work or the roadside across London and central England, inspects the tyre, and either repairs it to standard or fits a new one on the spot, usually within 30–60 minutes.
Frequently asked questions
Because the nail is partly plugging the hole it made. While it stays in, the tyre may lose air slowly or hardly at all. Pull it out and you can turn a slow leak into a rapid deflation, leaving you with a flat tyre instead of a repairable one.
If the tyre is holding pressure and the nail is in the tread, you can usually drive a short distance carefully at low speed to a safe place or a fitter. If the tyre is soft or losing air, do not drive on it — call for help instead.
No. Only punctures in the central three-quarters of the tread, that are small enough and not too close to a previous repair, can be fixed to British Standard BS AU 159. A nail in the sidewall or shoulder, or a large hole, means the tyre must be replaced.
Only as a last resort to get to safety. Sealant is a temporary get-you-home measure, can prevent a proper repair afterwards, and many products are not compatible with TPMS sensors. A professional plug-and-patch repair is the only durable, standard-compliant fix.
Possibly not. Repairs are only allowed in the central three-quarters of the tread, so a nail near the shoulder may fall outside the repairable zone. A fitter will measure its exact position and tell you honestly whether a repair is permitted or a new tyre is needed.
A nail itself may not, but the resulting damage can. If the puncture has caused a cut, a leak, or sits where it cannot be safely repaired, the tyre may be unroadworthy. The safest course is to have it inspected and repaired or replaced promptly.
