TYRE CARE AND MAINTENANCE TIPS ON TYRE MAINTENANCE Any tyre, no matter how well constructed, may fail in use as a result of punctures, impact damage, improper inflation, overloading, excessive wear or other use conditions. A tyre is wear-sensitive and all tyres 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, injuries or death. To reduce the risk of tyre failure and to get the best performance from your tyres, follow these simple procedures.
CHECK TYRE PRESSURE 1. Check the pressure of tyres once a week. 2. Check the pressure in all tyres including the spare tyre(s) as well. 3. Tyre pressure should be checked against the vehicle manufacturer’s recommended pressure for the axle loads (or the tyre manufacturer’s recommended operating pressures). 4. Check the pressure when tyres are cold or when the vehicle has travelled less than two miles. 5. Use a reliable and accurate pressure gauge. 6. Ensure that valve extensions are fitted and working for inner twins. 7. If you are unsure on any aspect of tyre pressure or tyre condition take your vehicle to an approved fitting centre and speak to the experts.
CHECK TREAD DEPTH It is recommended that drivers consider changing their tyres before the legal limit of 1mm. Tyre tread depth should be checked at least once a month or at every fleet inspection, using an accurate tread depth gauge.
CHECK CONDITION OF TYRES 1. Clean the dirt from the valves and make sure that valve caps are fitted to each wheel. 2. Remove any stones and other objects embedded in the tread. Look out for any bulges, lumps or cuts to the tread and sidewalls. 3. Steering alignment should be corrected if front tyres show signs of excessive or uneven wear. 4. Rotation, Balancing and Wheel Alignment will help tyres wear out uniformly and extend tyre life. 72

NOTES: (1)
Recommended rim shown in bold.
(2)
The load and inflation pressure on a rim or wheel must not exceed the rim manufacturer’s recommendations, particularly for Drop Centre rims, whenever fitment for Light Truck tyres of higher ply rating is intended. Consult rim manufacturer to ensure that the rim - wheel is of sufficient strength for the load, inflation and service intended.
(3) The load and inflation pressure imposed on a rim or wheel must not exceed the rim – wheel manufacturer’s recommendations even though the tyre of a size and ply rating designated to assure proper mounting and fit on the rim may be approved for a higher load and inflation. Consult rim manufacturer to ensure that the rim wheel is of sufficient strength for the load and service intended.
