Due to a heavy focus on cost- and weight-saving measures, spare tyres are not provided in most new cars. Only about 40% of new vehicles have a spare - once considered an essential back-up item for the average motorist.

If your new car doesn’t have a spare wheel, it will come with a car tyre puncture repair kit instead.

These puncture repair kits are not terribly popular among drivers, but if you have one, you should know how to use a tyre repair kit

Note: You should always check your vehicle handbook for any fault remedy before carrying out any work on your vehicle. If you are unsure of what is required to fix any problems, please consult a professional.

Once you've detected a puncture, pull over and stop somewhere safe - ideally away from traffic.

Apply your handbrake and switch off the engine.

Turn on hazard lights if needed.

Get out and examine the puncture. Your car’s puncture repair kit will only fill holes of about 4 mm in diameter. This means dealing with a nail or screw is fine, but if the tyre is torn or the wheel is damaged, you'll need to call your breakdown recovery provider.


Where is my puncture repair kit?

Your car’s puncture repair kit will be in the boot - either in a side panel or under the boot floor. The kit features a bottle of sealant and a compressor for inflating the tyre.


What if I have a nail in my tyre?

If you have a nail in your tyre, do not attempt to remove it. Instead, unscrew the valve cap and attach the sealant bottle. Once attached, the sealant will spread around inside the tyre, hopefully sealing any holes.


Next, attach the compressor. This may be fixed through the bottle via a special mechanism, or you may need to remove the bottle and fix it directly to the valve - it depends on your model.

Attach the compressor to your 'cigarette lighter', aka the 12V charge socket. Then turn on the engine and start the compressor. Inflate the tyre to the level recommended in the handbook.


What if it fails to inflate?

If the tyre fails to inflate, roll the car forward to move the sealant around. If this doesn’t work, you may need to call your recovery service.

If you successfully repair the tyre, you can drive off - but gently and below 50mph. After a couple of miles stop to check your tyre pressure.


Remember this is just a temporary fix. You'll need to get a new tyre - and a new bottle of sealant.

Tubeless tyre repair kit

These tyre repair kits are not supplied by car makers, but they can be effective in addressing a tyre puncture on a temporary basis. They are designed for objects like nails or screws.


  • Remove the screw or nail
  • Use the provided reamer tool to clean and enlarge the hole
  • Move it in and out of the hole - this will take some effort
  • Take one of the sticky rubber strips provided
  • Feed it halfway through the eye of the strip insertion tool
  • Add the provided tube cement to the strip
  • Push the strip into the hole - but not all the way in
  • Yank out the insertion tool, then cut away excess strips


Again, this is a temporary fix. You’ll still need to buy a new tyre.
