Can You Repair Puncture?
Factors Determining Tyre Repairability
- Location of the Puncture:
- Tread Area: Repairable if within the central ¾ (minor repair area) and the puncture is ≤6mm in diameter. Driving on a flat tyre may cause irreparable damage.
- Sidewall: Not repairable due to high structural stress and risk of failure.
- Shoulder Area: Also not repairable.
A clear visual guide to determine when a tyre can be repaired or needs replacing.
- Size of the Puncture:
- Maximum repairable diameter is 6mm. Larger damage, splits, cuts, or gouges require tyre replacement.
- Tyre Condition:
- Legal tread depth in the UK is 1.6mm. Repairs are not possible if tread depth is below this or if sidewalls show bulging or exposed cords.
- Run-Flat Tyres:
- Cannot be repaired due to difficulty assessing internal structural damage caused by driving on the punctured tyre.
Risks of Driving on a Flat Tyre
- Sidewall Damage: Driving on a deflated tyre can crush and damage the sidewall, making repairs impossible.
- Structural Weakening: Prolonged low-pressure driving can lead to mottling, chattering, or dislocation, compromising safety.
Repair Methods:
- PRP (Mushroom Plug): Most reliable and safe method.
- Wick or Patch Repairs: Not recommended due to inadequate internal inspection and potential for failure.
Tyre Repair Kits:
- Suitable only for temporary use to reach a garage.
