A tyre puncture repair is the process of fixing a damaged tyre that has lost air due to a small hole or sharp object such as a nail or screw. The goal is to restore safe air pressure and ensure the tyre can be used again without replacing it.
Most punctures happen when a tyre runs over sharp debris on the road. Nails, glass, screws, and rough road edges are typical causes. Slow leaks can also develop if the valve or inner lining is damaged.
A technician first removes the tyre from the wheel to inspect the inside and outside for damage. If the puncture is in a repairable area, it is sealed using a plug, patch, or a combination of both methods. The tyre is then tested for leaks before being refitted and reinflated.
A tyre can usually be repaired if the damage is small and located in the central tread area. If the puncture is on the sidewall or too large, a repair is not considered safe and the tyre must be replaced.
Driving on a punctured tyre can be dangerous because it reduces grip, stability, and braking performance. Even after a repair, the tyre should be checked regularly to ensure it maintains correct pressure and does not develop further issues.
Tyre puncture repairs are a quick and cost-effective way to fix minor damage and extend the life of a tyre. However, not all punctures are repairable, and safety always determines whether repair or replacement is the correct option.
