Puncture Repairs for Tyres

Australian standards draft

There is a draft code of practice that must be adhered to when undertaking repairs to Pneumatic tyres, – Tubeless and Tube tyre.

To ensure that all tyres are repaired correctly and in a proper manner you need to apply the following policies.

  • The tyre must be removed from the rim and completely inspected.
  • All punctures must be sealed internally and the holes must be filled to prevent moisture from entering in to the seal belts.
  • Any process that offers to seal the tyre, whilst on the tim either through the tyre or valves is against the above standards.
  • Penetrating minor repairs are not permitted to the shoulder, sidewall or bead areas of the tyre.
  • Passenger tyres have an allowable maximum minor repairs of 6mm diameter in the crown area only.
  • Light truck tyres up to 185mm – 6.50 have a maximum minor repair of 6mm.
  • Light truck tyres larger than 185mm have a maximum minor repair of 8mm.
  • Truck tyres have a maximum minor repair of 10mm.
  • Tyres may have an many minor repairs necessary or feasible as long as they do not overlap.
  • All repairs, larger than recommended, or outside the crown area, must be classed as major repairs.

Rules for Minor Repairs.

When a puncture repair is carried out correctly, it must meet certain criteria:

  • The tyre’s carrying capacity should not change.
  • The tyre’s speed rating may change (Please refer to repair manufacture)
  • The repaired area is within the maximum allowable dimensions and should maintain the tyre’s original strength.
  • The repair should meet the manufactures requirements/
  • The repair should seal in the air pressure while sealing out water from the internal belts.
  • The repaired channel should follow the original injury/
  • The Australian Standards allow the minor repair of “V” and “Z” rated tyres (repair materials must be compatible to speed rating of the tyre)
  • The tyre if designated tubeless and if the bead area still in sound condition should remain tubeless when repaired.
  • Combination or separate plug and patch are recommended for use to minor repair tyres to meet the Australian Standard.

Temporary Puncture Repair

The use of Fibre Cord Repair Materials may be used to repair minor punctures. It must be noted that the use of such materials is classed as a Temporary Repair measure to get the drive out of trouble. The tyre MUST be check properly by a trained person to assess whether the tyre is still structurally sound and the tyre should be re-repaired.
