Can a Punctured Tyre Be Repaired?
If you’ve picked up a puncture, don’t panic. Many punctures can be safely repaired, but not every tyre is suitable for repair. The location and size of the damage, along with the tyre’s overall condition, will determine whether it can be repaired or needs to be replaced.
The safest option is to have the tyre inspected by a qualified tyre professional. They can assess the damage and recommend the appropriate course of action. Visit your nearest Giti retailer for expert advice and service.
Australian Standards for Tyre Repairs
Tyre repairs in Australia should be carried out in accordance with Australian Standard AS 1973, which sets out when a tyre can be safely repaired.
Repairable Area
Only punctures located within the central tread area—approximately the middle 60–70% of the tyre’s width—can generally be repaired.
Areas That Cannot Be Repaired
Damage to the sidewall, shoulder, or within approximately 6 mm of the sidewall cannot be safely repaired. These areas flex significantly during normal driving, making repairs unreliable and unsafe.
Maximum Puncture Size
As a general rule, punctures larger than 6 mm in diameter should not be repaired. If the damage exceeds this limit, replacing the tyre is the safest option.
Why Professional Repairs Matter
A proper tyre repair involves much more than simply plugging a hole. Qualified tyre technicians follow industry-approved procedures to ensure the repair restores the tyre’s integrity as safely as possible.
A professional repair should include:
- A combination plug and patch to seal both the puncture channel and the tyre’s inner liner.
- Removal of the tyre from the wheel so the inside can be fully inspected.
- A complete internal inspection to identify hidden structural damage that may not be visible from the outside.
- No use of inner tubes to repair punctures in tubeless tyres, as this is not considered an appropriate repair method.
Temporary puncture repair kits or external plugs may help you reach a tyre retailer in an emergency, but they should never be considered a permanent repair.
When a Tyre Should Be Replaced
A tyre should be replaced if:
- The puncture is outside the approved repair area.
- The damage exceeds 6 mm in diameter.
- The sidewall or shoulder has been damaged.
- The tyre has suffered internal damage from being driven while under-inflated or flat.
- The tyre has multiple repairs or excessive wear that affects its safety.
If there is any doubt about a tyre’s condition, replacement is the safest option.
