Tyre and Rim Association of Australia
"Repairs to tyres
In order to ensure that tyres are repaired correctly and
continue to be considered roadworthy, the repair procedure
adopted by the Tyre and Rim Association of Australia should
be followed.
Tyres which have tread or casing separation or other damage
such as broken, kinked or exposed bead wires, or cracks or
cuts which extend into the tyre fabric should not be repaired.
Repairs are only allowed in the crown area of the tyre as
illustrated by the unshaded area in Figure 2. Repairs are not
permitted in the bead, sidewall or shoulder area of the tyre.
In order to carry out a satisfactory permanent repair, the
tyre must be removed from the rim as this is the only way
to adequately assess the condition of the tyre. The tyre
must be carefully examined for any damage or faults
which would make it unsafe for further use.
The tyre must be free of signs of delamination, pinching,
internal separation or any other sign of failure.
If the tyre is suitable for repair, the area to be repaired must
then be properly prepared on the inside of the tyre and
an appropriate patch or mushroom headed plug installed,
and vulcanised from the inside. In all repairs, external
damage must be properly sealed to prevent moisture and
contaminants from entering the structure of the tyre carcase.
Repair of punctures in tubeless tyres by insertion of plugs
or loops of adhesive, or sealant impregnated cord, without
removing the tyre from the rim is not a satisfactory procedure.
This method is acceptable only as an emergency repair
in exceptional circumstances to enable the vehicle
to be driven to a service centre, where proper repairs
can be made.
Tyres marked with “Do not repair” must not be repaired.
Run flat tyres may have additional restrictions placed
on repair which can affect the capacity to repair the tyre.
It is recommended that you contact the tyre manufacturer
prior to repairing a run flat tyre."
