Is It Safe to Drive with a Nail in Your Tyre?
16th July 2026
Finding a nail lodged in your tyre can be worrying, especially if the tyre still looks fully inflated. You may be tempted to carry on driving and deal with it later, but even a small nail can cause the tyre to lose pressure without much warning.
So, can you drive with a nail in your tyre? Yes, you can, but you should only be driving to the nearest repair shop, ideally under 5 to 10 miles away. Although the nail may temporarily block the hole, it can move as the tyre rotates, allowing air to escape and increasing the risk of further damage.
What should you do if you find a nail in your tyre?
If you notice a nail or screw in your tyre, follow these steps:
- Do not pull the nail out. It may currently be slowing the air loss and removing it could cause the tyre to deflate quickly.
- Check whether the tyre looks flat or misshapen.
- If you have a tyre pressure gauge, compare the pressure with the figure recommended by your vehicle manufacturer.
- Look for bulges, cracks or other visible damage.
- Arrange for the tyre to be inspected as soon as possible.
If the tyre is flat, losing pressure quickly or is visibly damaged, do not continue driving. Fit the spare wheel if it is safe to do so or contact a breakdown service.
Can I drive with a nail in my tyre if it is not flat?
A tyre can still contain enough air to look normal even when it has been punctured. The nail may be acting like a temporary plug, but there is no way to know how long it will stay in place.
Continuing to drive could make the hole larger or cause the tyre to lose pressure. An underinflated tyre can affect steering, braking and stability while also creating additional heat and damaging the tyre internally.
If the tyre is holding pressure and there are no signs of serious damage, you may be able to travel a very short distance directly to a tyre specialist. However, you should seek professional advice first wherever possible and avoid high speeds, motorways and unnecessary journeys.
How can you tell whether the tyre is losing air?
Some punctures cause an immediate flat tyre, while others result in a slow loss of pressure.
Signs that the nail may have punctured the tyre include:
- The tyre pressure warning light appearing
- One tyre looking lower than the others
- The vehicle pulling to one side
- Steering feeling heavier than usual
- A ticking or clicking noise as the wheel rotates
- The tyre repeatedly needing to be inflated
Do not assume the tyre is safe simply because you have not noticed any of these signs. A small puncture may release air gradually, so the tyre should still be checked. Have a look at our car tyre safety page to get yourself clued up on tyres if something like this happens.
Can a nail in a tyre be repaired?
In some cases, yes. Whether the repair can be completed safely depends on several factors, including the size and position of the puncture and the overall condition of the tyre.
A nail puncture may be repairable when:
- The hole is within the central tread area
- The puncture is no more than 6mm in diameter
- The tyre has not been driven on while flat
- There is no serious internal or sidewall damage
- The remaining tread is in a safe and legal condition
Puncture repairs in the UK should follow the recommendations in British Standard BS AU 159. The tyre must be removed from the wheel so its internal condition can be properly assessed before a repair is approved.
When can a nail puncture not be repaired?
A replacement tyre will normally be needed if the nail has entered the sidewall or shoulder. These areas flex considerably while driving and cannot usually be repaired safely.
The tyre may also need replacing when:
- The puncture is larger than 6mm
- The tyre has more than one unsuitable puncture
- The internal structure has been damaged
- The tyre was driven on while severely underinflated
- The tread is excessively worn
- There are cracks, bulges or exposed cords
- A previous repair affects the damaged area
Run-flat tyres may require different treatment because driving on them after pressure loss can cause damage that is difficult to see. Their repairability depends on the tyre manufacturer’s guidance and their condition following inspection.
Should you remove the nail yourself?
Do not pull the nail out before the tyre has been inspected. Removing it can open the hole and cause the remaining air to escape much faster.
You should also avoid attempting a permanent repair at home. Temporary puncture sealants or repair kits may help you reach a safe location in certain circumstances, but they are not substitutes for a professional inspection and repair. Always follow the instructions supplied with the product and your vehicle.
If you use tyre sealant, tell the tyre specialist before they begin working on the tyre.
How much does it cost to fix a tyre with a nail in it?
The answer depends on whether the puncture can be repaired or the tyre needs to be replaced.
A professional will need to assess:
- The nail’s position
- The size and angle of the puncture
- Any internal tyre damage
- The tyre’s age and condition
- Remaining tread depth
- Whether it is a conventional or run-flat tyre
A repair will generally cost less than purchasing a replacement tyre, but price should never take priority over safety. If the damage falls outside the permitted repair area or the tyre is no longer in a suitable condition, replacement will be the safer option.
Does car insurance cover a nail in a tyre?
Standard car insurance policies do not usually cover everyday punctures caused by nails or road debris. However, separate tyre insurance or a vehicle protection policy may include puncture repairs or replacement tyres.
Check the terms of your policy, including any excess, exclusions and claim limits, before arranging work.
How can you reduce the risk of nail punctures?
It is not possible to avoid every sharp object on the road, but a few simple habits can reduce the likelihood of tyre trouble:
- Avoid driving over visible debris
- Take extra care near building sites and skips
- Check your tyre pressures regularly
- Inspect the tread for embedded objects
- Replace worn or damaged tyres promptly
- Investigate recurring pressure loss rather than repeatedly reinflating the tyre
Regular inspections can help identify a nail before it causes a complete loss of pressure.
Get your tyre checked by Merityre
A nail in your tyre does not always mean you need a replacement, but the damage must be inspected before that decision can be made. Ignoring the damage could turn a repairable puncture into more extensive tyre damage.
Visit your nearest Merityre branch for a professional tyre inspection. If the puncture can be repaired safely, the team will advise you on the appropriate repair. If a replacement is required, you can choose from a wide selection of tyres suited to your vehicle and budget.
