Is It Safe to Drive With a Nail in Your Tyre?
The short answer: it depends. If the nail is in the tread area and the tyre is still holding air pressure, you can usually drive carefully to a tyre shop for repair. However, you should NOT drive at high speed, for long distances, or on the motorway with a nail in your tyre.
What to Do When You Find a Nail
- Don't pull it out. The nail is actually acting as a plug, keeping some air in the tyre. Removing it will cause the tyre to deflate faster.
- Check the tyre pressure. If the tyre still feels firm and you can see air pressure on the gauge, you can drive carefully to a tyre shop.
- Drive slowly and directly to a tyre shop. Stay under 50km/h, avoid the motorway, and go straight to the nearest tyre repair service.
- If the tyre is flat, don't drive on it — but get to a tyre shop as soon as possible. Driving on a flat tyre causes permanent damage to the tyre structure and can damage your wheel rim. Call for mobile tyre repair instead.
When a Nail-Punctured Tyre Can Be Repaired
Most nail punctures can be repaired if:
- The nail is in the tread area — not the sidewall or shoulder
- The hole is smaller than 6mm
- The tyre hasn't been driven flat
- There's no internal damage visible when inspected
At Carter's Tyres Pukekohe, we remove the tyre, inspect it internally, and apply a permanent combination patch-and-plug repair. This costs from $35 and takes about 20 minutes.
When the Tyre Needs Replacing
The tyre cannot be repaired and must be replaced if:
- The nail has gone through the sidewall
- The tyre has been driven while flat (the internal structure is compromised)
- The puncture hole is too large (over 6mm)
- There are multiple punctures close together
- The tyre was already near the end of its life
Where Nails Come From
In the Franklin area, the most common sources of nail punctures include:
- Construction sites: Especially around Drury and Paerata where major developments are underway
- Roofing and building work: Roofing nails blown off sites by wind
- Farm tracks: Wire, staples, and fencing nails on rural roads around Waiuku and Tuakau
- Road debris: General litter and roadside rubbish
TPMS Warning Light
If your car has a Tyre Pressure Monitoring System (TPMS), a nail puncture will often trigger the low-pressure warning light on your dashboard. Don't ignore this light — check your tyres immediately. A slow leak from a nail can cause the tyre to go flat unexpectedly, which is dangerous at speed.

Frequently Asked Questions
How long can you drive with a nail in your tyre?
If the tyre is holding pressure, you can drive carefully to a tyre shop — ideally within the same day. The longer you leave it, the more likely the air will leak out and the tyre will become unsafe.
Will a nail in my tyre cause a blowout?
A nail itself rarely causes a blowout. However, if you continue driving as the tyre slowly deflates, the underinflation can generate excess heat, which could lead to a blowout at highway speed. Fix it promptly.
Can I plug the tyre myself?
Tyre plug kits are available, but they're only a temporary fix. For a permanent, safe repair, the tyre needs to be removed from the wheel and patched internally. We recommend getting a professional repair at Carter's Tyres.
