Puncture Repair

Puncture repair is the process of fixing a tyre that has been damaged by a foreign object such as a nail or screw. UK industry standards (BS AU 159) define the repairable area as the central three-quarters of the tread. Repairs must be carried out internally using a combination plug-patch method — external-only plug repairs are not considered a permanent solution. Sidewall punctures, run-flat tyres that have been driven on flat, and tyres with tread depth below 1.6mm cannot be repaired.
