Types of Puncture repairs & their pros & cons

There are three types of puncture repair commonly used around the globe for tubeless tyres.

  • Internal repair using a patch
  • Internal repair using Minicombi (plug)
  • External repair using a tyre string

Internal repair using a patch

Once the puncture hole is identified, the same is covered by an adhesive patch from inside.

Hence these patches are adhesive, certain factors like heat & moisture reduces its life and are less reliable when compared to Minicombi repairs

Internal repair using Minicombi (plug)

This method is done by inserting and sealing the puncture hole using a Minicombi from inside to outside.  This plug is sealed using rubber friendly sealants and other materials, hence this repair is considered the most reliable. Minicombi repair is also referred as mushroom repair.

 

 

 

 

 

 

 

 

 

External repair using a tyre string

External repair is done using a tyre string inserted to the puncture hole from outside. As they are not sealed, the string repair has a very short life compared to other repairs. Because it’s inserted externally, it’s unsure whether the string is inserted into the exact puncture hole or if any debris is left inside the puncture hole which in future may lead to air leakage and can cause damage to the tyre.
