1. PCR / 4x4 / LTR tyres

Any tyre, no matter how well constructed, may fail in use as a result of

  • punctures,
  • impact damage,
  • improper inflation,
  • overloading,
  • uneven wear due to misalignment
  • excessive wear ,
  • misapplication (incorrect tyre or rim for the vehicle) or
  • other abnormal use conditions beyond the design parameters of the tyre.

All tyres will eventually wear out. A worn or damaged tyre can present a safety hazard, and a tyre failure can lead to an accident that may result in property damage, personal injuries or death.

To reduce the risk of tyre failure, we advise as follows:

A. Tyre selection:

IMPORTANT INFORMATION is moulded onto the sidewall of the tyre.
Among other information, the sidewall contains the tyre size, load index, speed index and maximum pressure for that particular tyre. Consult your tyre dealer for more details on the load and speed index.

Always follow the instructions and recommendations of the vehicle manufacturer, as contained in the Vehicle Owner’s Manual:

  • Standard Tyres :
    Select the correct tyres as per the vehicle owner’s manual and fit onto the prescribed rim (diameter and rim width).
  • Run Flat Tyres (ROF)
    Run flat (or run-on-flat) tyres have been developed in order to minimize the risks associated with a tyre puncture. A puncture can lead to the driver losing control of the vehicle due to the deflated tyre’s loss of structure and possible dismounting from the rim during operation.

NOTES:

  1. If run-flat or run-on-flat tyres are specified for a vehicle, normally with the use of a built-in Tyre Pressure Monitoring System (TPMS), it is important that this specification is followed at the time when the tyres of the vehicle are being replaced. If in doubt, refer to the vehicle owner’s manual.
  2. Run flat tyres can operate without air in them at normal loads and operating conditions, but the vehicle may not be driven for a distance greater than 80 kms, and at a maximum safe speed of 80 km/hour, after which the deflated tyre must be replaced as per the vehicle owner’s manual guidelines.

B. Tyre mounting onto rim :

SAFETY WARNING:
SERIOUS INJURY OR DEATH MAY RESULT FROM EXPLOSION OF TYRE/RIM ASSEMBLY, IF PROPER MOUNTING INSTRUCTIONS AS BELOW ARE NOT FOLLOWED.

  • l ONLY specially trained persons should mount tyres.
  • l ALWAYS match rim diameter with tyre diameter.
  • l NEVER mount a tyre on a cracked, bent, rusted or otherwise damaged rim or a rim which has been repaired.
  • l NEVER put a flammable substance into a tyre.
  • l ALWAYS clean and lubricate the rim and tyre beads to ensure proper seating of tyre onto the rim.
  • l ALWAYS use an extension air hose with gauge and clip-on air chuck.
  • l ALWAYS lock the wheel on the tyre mounting machine, or place it in a safety cage when inflating.
  • l ALWAYS stand clear, and NEVER lean or reach over the tyre/rim assembly when inflating.
  • l NEVER inflate the tyre over 275 kPa to seat the beads.
  • l ALWAYS adjust tyre pressure to the vehicle manufacturer’s recommendations after the beads are fully seated (no gaps between rim flange and tyre).

C. Safe use of tyres:

  1. CHECK the air pressure in all your tyres, including the spare, frequently (minimum once per month) when tyres are cold (or after being stopped for three or more hours after a journey).

    Do not reduce air pressure when tyres are hot from driving. Use a tyre gauge to check the cold pressure and maintain it at the level recommended by the vehicle manufacturer.
  2. NEVER overload your tyres. The maximum load carrying capability of your tyre is moulded onto the sidewall of each tyre, in the form of an index. Consult your tyre dealer for conversion to weight.
  3. CHECK your tyres regularly for scrapes, bulges, separations, cuts, snags or embedded foreign objects. Show the tyres to your tyre store or dealer immediately if any such condition is discovered.
  4. NEVER operate your vehicle in excess of lawful speeds, beyond reasonable speeds for the driving conditions, or at speeds greater than recommended for the tyre you are using.
  5. MAKE every effort to avoid driving over objects that may damage the tyres through impact or cutting such as potholes, glass , metal or other road hazards.
  6. NEVER drive on smooth tyres. Always remove tyres from service and replace them when they reach the remaining 1.6 mm of tread depth - tread wear indicators are built into the tyre’s tread grooves to indicate when they are worn .
    NOTE : In South Africa, it is illegal to drive with tyres that have less than 1.0 mm remaining tread, in the absence of tread wear indicators.
  7. DO NOT spin tyres excessively on mud as this can cause damage to the tread, tyre explosion or disintegration as well as axle failure.


2. Truck and Bus Tyres

Any tyre, no matter how well constructed, may fail in use as a result of

  • punctures,
  • impact damage,
  • improper inflation,
  • overloading,
  • uneven wear due to misalignment
  • excessive wear ,
  • misapplication (incorrect tyre or rim for the vehicle) or
  • other abnormal use conditions beyond the design parameters of the tyre.

All tyres will eventually wear out. A worn or damaged tyre can present a safety hazard, and a tyre failure can lead to an accident that may result in property damage, personal injuries or death.

To reduce the risk of tyre failure, we advise as follows:

A. Tyre selection:

Among other information, the sidewall contains the tyre size, load index, speed index and maximum pressure for that particular tyre. Consult your tyre dealer for more details on the load and speed index.

Always follow the instructions and recommendations of the vehicle manufacturer, as contained in the Vehicle Owner’s Manual.

Select the correct tyres as per the vehicle owner’s manual and fit onto the prescribed rim (diameter and rim width).

It is also important to ensure that the correct tread pattern is selected for the service application and wheel position.

B. Tyre mounting onto rim :

SAFETY WARNING :
SERIOUS INJURY OR DEATH MAY RESULT FROM EXPLOSION OF TYRE/RIM ASSEMBLY, IF PROPER MOUNTING INSTRUCTIONS AS BELOW ARE NOT FOLLOWED.

  • l ONLY specially trained persons should mount tyres.
  • l ALWAYS match rim diameter with tyre diameter.
  • l NEVER mount a tyre on a cracked, bent, rusted or otherwise damaged rim or a rim which has been repaired.
  • l ALWAYS make sure that the inside of the tyre is dry before mounting. Moisture in the tyre can damage the casing.
  • l NEVER put a flammable substance into a tyre.
  • ALWAYS clean and lubricate the rim and tyre beads to ensure proper seating of tyre onto the rim.
  • l ALWAYS place tyre in a safety cage,and use an extension air hose with gauge and clip-on air chuck.
  • l ALWAYS inflate with dry air from a compressor with a properly working moisture filter.
  • l ALWAYS stand clear, and NEVER lean or reach over the tyre/rim assembly when inflating.
  • l NEVER inflate over 275 kPa to seat bead.
  • l ALWAYS adjust tyre pressure to the vehicle manufacturer’s recommendations after beads are fully seated.

C. Safe use of tyres:

  1. 1 CHECK the air pressure in all your tyres, including the spare, frequently (minimum once per week) when tyres are cold (or after being stopped for three or more hours).

    Do not reduce air pressure when tyres are hot from driving; use a tyre gauge to check the pressure and maintain it at the level recommended by the vehicle manufacturer.
  2. NEVER overload your tyres. The maximum load carrying capability of your tyre is moulded on the sidewall of each tyre in the form of an index. Consult your tyre dealer for conversion to weight per tyre.
  3. CHECK your tyres regularly for scrapes, bulges, separations, cuts, snags or embedded foreign objects. Show the tyres to your store or dealer immediately if any such condition is discovered.
  4. NEVER operate your vehicle in excess of lawful speeds, beyond maximum speeds by driving conditions or at speeds greater than recommended for the tyre you are using.
  5. MAKE every effort to avoid driving over objects that may damage the tyres through impact of cutting such as potholes, glass and metal etc.
  6. NEVER drive on smooth tyres. Always remove tyres from service and replace them when they reach the remaining 4 mm of tread depth to safely retread the tyre. In South Africa it is illegal to drive with tyres with less than 1 mm remaining tread depth.
  7. DO NOT spin tyres excessively on mud, as this can cause tread damage, tyre explosion or disintegration, as well as axle failure.
