Puncture Repairs

So you've had a flat tyre, what now?

The most immediate need when you have a flat tyre is to get back on the road. You will usually have to address this by removing the punctured tyre and fitting your spare, safely out of the way of any traffic.

However, it is critically important to organise for the punctured tyre to be repaired as soon as possible. This is especially the case if your vehicle's spare tyre is a space saver (or speed limited).

The area of the tyre where the puncture occurs will determine if the tyre is repairable. Generally tyres with punctures in the tread area are repairable.

A flat tyre is generally caused by a puncture to a tubeless tyre's casing, allowing air to escape and causing the tyre to deflate. Punctures are usually caused by sharp objects like small nails and screws.

These objects tend to cause punctures less than 5mm in diameter. If they occur within the tread area of the tyre, a repair can usually be made to the tyre.

Repair area


Areas within the central ¾ of a tyre (shown in blue) which have a tread depth of no less than 1.6mm are minor repair areas.

Tyres can often be beyond repair and will need replacement if there are sizeable punctures to the tread or punctures in the tyre's shoulder or sidewall areas.

The function of a puncture repair is to seal the tyre's casing to prevent moisture or contaminants from entering the tyre casing or structure. The tyre must be removed from the rim to perform a correct puncture repair. This allows for a complete inspection of the damage and ensures the plug used to repair the puncture bonds properly with the tyre casing to make it air-tight. The repair is made from the inside out.

A puncture repair usually takes around 30 minutes to complete. It involves deflating and removing the flat tyre from the rim, assessing and repairing the puncture before re-fitting it to the rim and balancing the tyre on the wheel. It is then fitted to your vehicle and your spare placed back into storage.

If you have any questions regarding tyre repairs, please speak to one of our expert staff.
