Not every puncture is repairable, and attempting to tyre puncture repair the wrong type can compromise your safety. Punctures in the central tread area may be repairable if the hole is within an industry-accepted diameter. Damage to the shoulder or sidewall is typically not repairable, and replacement is recommended. Tyres driven on while flat can suffer internal structural damage that makes a safe repair impossible, even if the outer appearance looks fine.
Signs that a tyre may not be repairable include the following:
▸ A puncture in the sidewall or shoulder zone.
▸ A large tear, cut, or hole exceeding repairable limits.
▸ Visible bulging or internal bead damage from driving on a flat.
▸ Significant tread wear that makes a repair uneconomical.
