Fixing Car Tyre Puncturesthe Hassle-Free Way!

June 22, 2017

At times, car tyre replacement may seem like an unwanted expense especially due to the intimidating purchasing experience. This is most important when getting a flat or puncture but no need to fret as there’re many easy ways to repair the painless way. You can do so for a fraction of the new tyre’s cost if;

  • Puncture happens in the main tread area and
  • You quickly stopped with overheating the deflated tyre

A careless or bodged repair can be dangerous and many countries have clear laws of car tyre replacement for unrepaired punctures. What’s more important is the removal of tyres from the wheel to check for internal damage that may later cause imminent failure in undetected.

Here, it’s important to clarify that externally applied plugs and liquid sealants that are injected through the tyre valve aren’t to be considered as permanent repairs.

Tyre sealants

For new cars, it’s common to come with a tyre sealant and a complete inflator pack instead of just a spare wheel. Compressed air and the sealant are then injected through the tyre valve however, successful outcome would be determined through;

  • Cause of the puncture in the first place
  • Position or area of the lesion and
  • Total distance and speed at which you’ve been driving on a flat tyre

In case any of the factors comes missing or give negative output, car tyre replacement is the only option. There’re basically two types of sealant namely;

  • Pre-puncture that are put into the tyre before puncture actually happens as a safety precaution
  • Post-puncture sealant is applied after the puncture

Let’s have a look at both in detail

Pre-puncture sealants

  • These are injected through the tyre valve with the aim of preventing air loss just in case a puncture occurs thereby ensuring a smooth ride without unwanted interruption.
  • If the sealant actually works, the seal them would be quite instantaneous thus raising concerns of whether there’s been a puncture or not.
  • A nail or a large screw sealed into the tread unnoticed may cause more damage overtime that may lead to imminent blowout.
  • It’s important checking the tyres every time before taking the vehicle out for a spin. In case the sealant’s activated, there’d be clear sign of a whitish latex on the tyre’s exterior.

Post-puncture sealants

  • Here, it’s important to spot a puncture and halt the car before the tyre actually shred into pieces due to overheat that may also damage the wheel rim
  • The sealant is injected through the tyre valve and cylinder or compressor of the compressed gas is used for re-inflation.
  • These are handy when you’re a casual solo driver however, not recommended for all punctures as there’re times when car tyre replacement is the best option.


Whatever sealant you’re going with, it isn’t a permanent repair solution as the tyre hasn’t been taken off the wheel for detailed internal damage. Some laws even emphasise to enlist the type of damage, materials and methods implemented to repair followed by a statement.
