Tyre sealant - the quick fix for punctures


So, you’ve got a flat. There’s no spare tyre and whether you’re in an urban jungle or somewhere in the sticks, you’re not going anywhere.

It’s actually common for vehicles to have no spare on hand. Instead, manufacturers provide a method of inflating and temporarily sealing a punctured tyre to ensure you get moving again – at least far enough to get it replaced.

Tyre sealant is a product that is still relatively unknown. It’s designed to offer a temporary roadside repair to allow you to get to a place where the tyre can be taken in for replacement.

Before you set off on the road again, the sealant needs to be inserted through the valve of the damaged tyre so that it can seal the hole. While some vehicles have air compressor systems incorporated into the tyre sealant, other methods offer a ‘one can does all’ solution.

For vehicle systems that have a 12volt air compressor system incorporated into the tyre sealer product (pictured). Simply plug this into the vehicle’s power socket and you’re good to go. Turn the dial one way and it squirts the liquid into the tyre, turn it the other way and the tyre inflates – it’s as easy as it sounds. Be sure to keep an eye on the dial on the gauge, though, so you can stop the compressor when the correct tyre pressure has been reached.

For those who don’t have this incorporated system in place, automotive suppliers provide a ‘one can does all’ solution that inflates and seals in one go. However, the downside of this method is that, once the can’s empty, you have no indication of tyre pressure, and if the sealant hasn’t worked quickly enough before the air starts to be pumped back into the tyre, it could leave your tyre underinflated – unless you happen to have an electric tyre pump to hand to finish the job.

Whichever method you use, once the temporary repair is in place, and before you set off again, it’s always a good idea to wait a few minutes. Listen out for hissing noises from the repaired area and make sure the tyre is holding pressure.

Always follow the manufacturer’s instructions when using this method and never put the sealant inside tyres to avoid potential punctures – it’s only meant as a temporary and preventative repair, in the event that a puncture actually happens, and misuse could cause damage.
