Before beginning a tyre repair, the tyre must be removed from the wheel assembly. To conduct a safe tyre repair, a thorough tyre inspection is required. Not all unsafe conditions are visible from the outside of the tyre. Removing the tyre from the wheel assembly allows a thorough inspection of the exterior and interior walls of the tyre to determine if any hidden damage may be present.
The first consideration when evaluating if a tyre can be repaired is to confirm the type, size, and location of the damage.
- Repairs are limited to the tread area only. Do not repair a tyre if the injury extends into the shoulder or sidewall area. In this situation, the tyre must be replaced.
- Punctures greater than ¼ of an inch or 6mm are prohibited. Full tyre replacement is required if punctures exceed this limit. Repairs to larger tread punctures, irregular gashes, or cuts exceeding ¼ of an inch are not permitted. If cuts have sliced through the tyre’s steel belts it reduces the strength and durability of the tyre, making it unreliable and unsafe.
- Repairs can never overlap. If new damage compromises a previously repaired area, the tyre will not be safe to repair.
- Patching, by itself, is never a suitable repair. Proper repair procedures dictate that the injury must first be completely filled with suitable vulcanizing material or solid rubber stem. Secondly, a patch must then be applied to the inner liner to complete the repair.
Not all tyres qualify to be repaired. Some tyres have special repair limits, and others may have suffered damage too extensive to repair. The end results of returning a permanently weakened, or incorrectly repaired, tyre to service could be catastrophic.
How is a tyre properly repaired?
- The tyre is demounted and inspected internally as well as externally. It is then patched from the inside and the puncture hole is filled.
- Do not have your tyre plugged. A plug is simply inserted into the punctured area, making it unreliable.
Tyres should be repaired by a tyre professional.
