Discovering a tyre puncture can be alarming but fixing the issue may be more straightforward than you think. Most modern vehicles are now equipped with a tyre puncture repair kit rather than a spare tyre, making emergency tyre repairs much quicker and simpler. If you’ve never had to use a tyre puncture repair kit, the task may seem daunting, but we’re here to help.

In this blog, we’ll cover how to use a puncture repair kit so you can get your car safely to a garage as soon as possible.

What is a tyre puncture repair kit?

Tyre puncture repair kits are a modern alternative to spare tyres, helping motorists spend less time trying to fix punctured tyres at the side of the road. The repair kit should consist of tyre sealant and a tyre inflator. It’s important to remember that tyre puncture repair kits are only a temporary fix that can help you get to a garage to have your tyres looked at properly.

How do I know if my tyre is punctured?

If you’re driving on a punctured tyre, either your tyre pressure warning light will appear on your dashboard, you’ll feel the steering wheel vibrate or the car will pull to one side. If this occurs, it’s important to pull over to the nearest safe place, away from the traffic, so you can assess the punctured tyre.

How do I repair a tyre puncture myself?

If you’re on the road and looking to repair a tyre puncture yourself, follow these steps:

Make sure you’re in a safe place

Before you start doing anything, make sure your car is parked in a safe place, away from busy traffic. You should switch off your car engine and put on your hazard warning lights to alert other road users.

Read the instructions

The puncture repair kit can usually be found in the car boot. Make sure you read the instructions on the puncture repair kit before you begin to avoid any confusion.

Locate the tyre puncture

Once you’ve located the puncture, you need to assess whether it’s repairable. You shouldn’t use a puncture repair kit if:

  • The puncture has a diameter of more than 4mm.
  • There is damage to the wheel rim.
  • The puncture is on the tyre sidewall
  • The tyre has been flat for some time.

If you notice a nail or something else that has pierced the tyre, do not try to remove this as it could worsen the damage.

Position the tyre

Position the tyre so that the puncture is at the top and the air valve is in the top half of the tyre. This will make the repair easier and more accessible.

Squeeze in the tyre sealant

Remove the valve core on the tyre and squeeze in the tyre sealant, following the instructions on the bottle, then screw the valve core back in.

Inflate the tyre

Use the tyre inflator to pump up the tyre to the recommended tyre pressure. The recommended tyre pressure for your vehicle can be found in your vehicle handbook, in the door sill on the driver’s side or inside the fuel cap.

Test if the tyre sealant has worked

You may need to drive a short distance for the tyre sealant to work its way around the tyre. The bottle will explain if this is the case and how far to drive. Once you have done this, pull over to a safe place again to check if there is any further damage to the tyre. If the tyre looks intact, you can drive to a garage to have the tyre inspected further.

Be mindful of your speed when driving on a repaired tyre. It’s important to drive carefully to avoid any further damage to the tyre. The tyre sealant bottle may advise a maximum speed limit.

Replace the tyre

As mentioned previously, tyre puncture repair kits are a temporary fix. Once you’ve taken your car to a garage, they will assess the tyre to establish whether it can be fixed permanently or if it needs to be replaced.

Can a tyre puncture be fixed permanently?

Whether punctured tyres can be fixed permanently depends on the severity of the puncture. If the puncture is less than 6mm in diameter and in the middle three-quarters of the tyre’s width, then it can likely be fixed. However, more severe punctures can cause internal damage to the tyre and can lead to further problems if you continue driving. In these instances, punctured tyres will need to be replaced. In either case, tyre sealants are a temporary solution to help you get your car to a garage to be further assessed.
