Repair Criteria Checklist

For a tyre to be safely repaired, it must meet all of the following criteria:

• Location: The puncture must be within the central 75% of the tyre’s tread (the “minor repair area”). Punctures in the sidewall or shoulder cannot be repaired as these areas flex too much.
• Size: The object that caused the puncture must be no larger than 6mm in diameter.
• Tread Depth: The tyre must have at least 2mm of tread remaining (above the 1.6mm legal limit).
• No Previous Repairs: The tyre cannot have been repaired before in the same area.
• No Structural Damage: There must be no damage to the tyre’s internal structure from driving on it while flat.

Step 1: Removal & Inspection

We remove the tyre from the wheel and conduct a thorough inspection of the inside and outside to locate the damage and check for any secondary damage caused by the object or by driving on the flat tyre.

Step 2: Preparation

The area around the puncture is cleaned and prepared. The puncture channel is reamed to create a clean, uniform hole for the repair plug to seal against.

Step 3: Plug & Patch

We use a combination plug-and-patch unit. The plug seals the puncture channel from the inside, and the patch is chemically bonded to the inner liner of the tyre. This creates a permanent, airtight seal.

Step 4: Sealing

The patch and plug are coated with a special sealant to ensure a perfect, permanent bond and prevent any air loss.

Step 5: Refitting

The tyre is refitted to the wheel, inflated to the correct pressure, and professionally balanced on our computerized wheel balancer to eliminate any vibrations.

Step 6: Final Check

The repaired area is checked for any leaks before the wheel is torqued back onto your vehicle to the manufacturer’s exact specifications.
