Tyre Examination & Repair

SHARE

Inspect tyres regularly, paying attention to:

 

Objects embedded in the tread

Remove all stones and other objects embedded in the tyre tread before driving.

Tread wear

Ensure tyres have adequate tread depth. If your tyres are worn to the tread-wear indicators they must be replaced. Tyre wear indicators are positioned at equal distances around the tyre and may be located by the symbol TWI in the very upper part of the sidewall in the shoulder area where that meets the start of the tread pattern.

Sidewall condition

If there are bulges and cuts, have the tyre examined by JAX Tyres, as the damage may be more serious than it appears.

Note: Tyres showing wear on one side, or showing feathered edges to the tread pattern, are often indicative of mechanical maladjustment. The vehicle's steering, or suspension geometry may need to be checked, and the wheels aligned.

WARNING! All punctured or damaged tyres must be removed from the wheel for internal and external examination to ensure there is no hidden secondary damage which may later cause tyre failure. Puncture repairs must meet Australian standards.

 

Repairs to Run Flat Tyres

A number of leading car manufacturers, have started to equip their vehicles with Run Flat or Mobility Tyres.

This revolutionary tyre design allows the vehicle to continue moving despite a loss of tyre pressure and is
able to function as a "get home" solution. This avoids the inconvenience of all that may be associated with
changing the tyre at the roadside.

Run flat tyres are designed to have a "get you home capability" and depending on the particular tyre brand, can
be operated up to a distance of 100km, provided the maximum speed of the vehicle does not exceed 80km/hr.

When punctured and operated in a deflated state, the tyre condition will have to be carefully assessed to
evaluate the suitability and integrity of the tyre’s casing prior to carrying out any repair.

There are specific guidelines for the repair of run flat tyres and it should be noted that not all tyre
manufacturers approve of the repair to their products.

Prior to repair, JAX Tyres will conduct a thorough examination to ensure the suitability of conducting a repair to a run flat tyre, in accordance to the Australian Tyre Standard, the tyre manufacturer's recommendations and any damage likely to be caused by the tyre running underinflated


Goodyear - Minor repairs to Goodyear EMT or ROF run flat tyres may be repaired in accordance to the Australian Tyre Repair Standard.

Hankook - Minor repairs are permitted in accordance to the Australian Tyre Repair Standard.

Michelin - Michelin ZP (Zero Pressure) run flat tyres may be repaired in accordance to the Australian Tyre Repair Standard but hailed to only one repair. In the event of more than one penetration the tyre must be replaced.

Pirelli - In accordance to Pirelli's technical recommendations their run flat tyres cannot be repaired after being punctured and must be replaced.

Tyre Performance and WearTyre Performance and Wear.png

Throughout the life of a tyre, its performance gradually decreases, compromising your safety particularly when driving in the wet. In these conditions, the tyre's ability to provide adequate grip when accelerating, cornering and braking reduces to unacceptable levels at the minirnum tread depth of 1.6mm.
For these reasons, most manufacturers recommend replacing worn tyres at a minimum tread depth of 3mm.

 

Repairs to Self Sealing Tyres

Repairs to Seal Inside Tyres may be made in accordance to the Australian Tyre Standard.
Following a penetration, during the repair procedure it will be necessary to remove the internal sealant in the area of the penetration equal to the size of the repair patch to expose the impermeable butyl liner.
The removal of the sealant will mean that the patched area will lose its special technical characteristics of a Seal Inside tyre

Standard Repairs

Standard Repairs

  • Punctured tyres to be repaired, must always be removed from the wheel for inspection
  • JAX Tyres will ensure that your tyre is repaired according to the Australian Tyre Repair Standard
  • Any penetration causing a hole in the tread area not exceeding 6mm diameter may be repaired
  • If the penetration is greater than 6mm or is localised either in the sidewall, shoulder or bead area of the tyre then it is unrepairable and must be replaced to ensure that your safety is not compromised
