Tyre Repair
[ Back to Index ]
Repairing a tyre is not as straightforward as you first might think.
Tyre repairs are covered by BSAU159f:1990 which splits repairs into
two categories - minor repairs and major repairs. The British Standard also defines
limits to the location, size and number of repairs that can be carried out and makes
recommendations also on the repair materials to be used.
A tyre must always be checked thoroughly before it is repaired. If
the tyre displays any of the following, it should not be repaired;
- Illegal tread depth (below 1.6mm across the central ¾ of the tyre tread throughout the entire circumference)
- Run flat damage
- Secondary damage - caused by the injuring object
- Ageing/deterioration of tyre rubber
- Bead damage
- Exposed cords
