TYRE TIPS AND RECOMMENDATIONS.
How to increase the life of your tyres is solely dependent on the ability and willingness of the vehicle owner in maintaining correct tyre pressures on a regular basis. These tips will assist you to set up a simple, and regular, tyre check, thus ensuring longer tyre life and, and more important, you and your families safety.
Ø TYRE PRESSURE: Most tyre damage is due to, or aggravated by incorrect tyre inflation pressures. In addition, it is a major factor in the road holding and stability of your vehicle. Correct pressures are related to speed, load and vehicle performance and are vital for even braking, maximum grip and tyre life. Pressure checks should be conducted fortnightly, whilst tyres are COLD, with an accurate tyre pressure gauge. DO NOT inflate/deflate tyres whilst tyres are hot, as pressure does increase during operation. Tyre pressures should be the same for both tyres on the same axle.
Ø UNDER INFLATION: Prolonged under inflation causes excessive flexing and deterioration of the casing with excessive shoulder wear on either side of the tread area.
Ø OVER INFLATION: Uncomfortable and unstable ride with reduced tread surface and road contact, resulting in excessive wear in the centre on the tread area.
Ø VALVE CAPS: Valve caps act as a supplementary air seal and MUST be fitted at all times. Failure to fit valve caps allows dirt to enter into the valve core which will result in air loss due to the inner core spring malfunctioning and not allowing the valve to seal.
Ø PRESSURE INCREASE: As previously mentioned, tyre pressures increase during running, which is normal. NEVER adjust tyre pressures whilst tyres are hot as the tyre manufacturers allow for this increase when designing the tyre. Nitrogen is highly recommended as a substitute for ordinary air. (See our explanation and reasons on Nitrogen fill under Technical).
Ø TYRE DAMAGE & MAINTENANCE: When a tyre has suffered a violent impact against an obstacle (kerb, pothole etc) the tyre must be inspected by a competent tyre technician, as interior damage may be present, which will lead to sudden tyre failure. All FIRESTONE steel belted passenger tyres are issued with Firestone’s FREE All Road Hazard Guarantee. (See FIRESTONE’S explanation and terms and conditions of the All Road Hazard Guarantee)
Ø ABNORMAL TREAD WEAR: Abnormal tread wear will be visible and be an indication of a mechanical defect of the vehicle. Each wear pattern or combinations of wear patterns, will indicate definite mechanical problems i.e. incorrect inflation, incorrect wheel alignment, shock absorber failure, worn stabiliser bushes, play in steering mechanism, high spotting on brakes and tread separation on tyre. It will be necessary to have these faulty items checked and corrected or replaced/repaired.
Ø WHEEL ALIGNMENT: Depending on the roads that you normally drive on, the wheel alignment of your vehicle is a vital and necessary item to maintain. We highly recommend that alignment be set every 8,000 to 10,000 klm’s. Driver fatigue can and is caused by misalignment of your vehicles suspension, especially on an extended trip. (See our technical explanations under Technical) We have, installed, two of the latest HUNTER DSP600 aligners.
Ø WHEEL BALANCING & TYRE ROTATION: All tyres must and should be rotated every 8,000 to 10,000 klm’s. A static and or dynamic unbalance of the wheel/tyre assembly, besides promoting abnormal tyre wear, will cause handling and vibration problems. We are able to fine balance problematic tyre/rim assemblies.
Ø TYRE ROTATION: Tyres should be rotated every 8,000 to 10,000 klm’s. DO NOT cross rotate (left to right/right to left). Tyres must be rotated from front to back/back to front, thus keeping the tyres on the same side of the vehicle. Be aware that certain vehicles do not have the same sized tyres on the front as are on the rear. Tyre rotation must NOT be conducted in this instance.
Ø WHEEL NUT TORQUE: When removing and refitting a tyre/wheel assembly, ensure that wheel nuts or studs are tightened to the correct torque measurement. (See our torque recommendations under Technical).
All of the above points are extremely important in obtaining maximum mileage and service from your tyres. Should you be experiencing problems, and believe that we have not covered it above, feel free to contact us, as we specialise in all the above.
