There’s nothing quite like that sinking feeling when you realise you might need a tyre puncture repair. Whether it’s caused by a nail, a slow leak, or a sudden loss of pressure, a puncture can turn a smooth journey into an instant headache.
The good news is that many punctures can be repaired safely and affordably — as long as you catch them early and know what to do next.
In this guide, we’ll explain how to spot a puncture, when a tyre can be repaired, and what to do if you find yourself dealing with one while out on the road.
How to Spot a Tyre Puncture
Sometimes, it’s obvious: a flat tyre or a loud hiss gives the game away. But other times, the signs are subtle. Watch out for:
- The car pulling to one side
- A soft or bouncy steering feel
- A vibration or thumping sound from one corner
- A low-pressure warning light on your dashboard (if fitted)
If you suspect a puncture, pull over safely and check your tyres before driving further. Continuing to drive on a flat tyre can quickly destroy it — and may even damage your alloy wheel.
Can My Tyre Be Repaired?
Not every puncture is repairable, but many are. Here’s what garages look for:
Position of the puncture:
If the damage is within the central three-quarters of the tread, it’s usually repairable.
If it’s on or near the sidewall, it’s not safe to repair — a replacement is needed.
Size of the hole:
Punctures up to 6mm wide can typically be fixed. Anything larger usually means a new tyre.
Tyre condition:
If the tyre shows splits, cuts, or exposed cords — or if it’s been driven while flat — it must be replaced.
How Garages Work a Tyre Puncture Repair
Most UK garages follow the BS AU 159 standard, which ensures repairs are both safe and long-lasting. The process usually involves:
- Removing the tyre and inspecting it inside and out.
- Finding the puncture, often using a water or soap test.
- Preparing and cleaning the area around the damage.
- Applying a plug and patch from inside the tyre to seal it completely.
- Rebalancing and refitting the tyre to your wheel.
Tyre repair cost
A proper tyre puncture repair normally costs around £20–£30, takes less than an hour, and can last the lifetime of the tyre.
Temporary Fixes and Sealant Kits
Most modern cars come with a tyre repair kit instead of a spare wheel. These kits inject sealant into the tyre and inflate it enough to get you to a garage.
They’re handy in an emergency, but remember:
- They’re temporary — drive no more than 50–100 miles.
- The sealant can sometimes prevent a full repair later, depending on how it spreads.
If you use one, head to a tyre specialist as soon as possible for a professional inspection.
DIY Plug Kits – Use with Caution
DIY tyre plug kits can help in a pinch, especially on rural roads or out of hours. But they’re not a long-term solution. They don’t seal the tyre from the inside, so they should only be used to get you home or to a garage — not as a permanent fix.
How to Avoid Punctures Altogether
You can’t dodge every screw or shard of glass, but a few simple habits go a long way:
- Check your tyre pressures monthly (and before long journeys).
- Avoid kerbs and potholes where you can.
- Regularly inspect tyres for nails, stones, or cracks.
- Rotate and balance tyres during routine servicing.
A little attention can add thousands of miles to your tyres’ lifespan.
Bottom Line
A puncture doesn’t always mean a new tyre. Many can be repaired safely and affordably if caught early — saving you money and reducing waste.
If you’re not sure, ask a trusted garage to inspect it before replacing it.
