GENERAL TYRE TIPS
TYRE PRESSURES OFF-ROAD
- It is important to remember that it is air inside the tyre that carries the load, not the tyre.
- Heat due to over deflection is the greatest enemy of a tyre.
- To avoid excessive heat build up caused by over flexing, you must ensure that there is sufficient pressure to carry the load.
- In most conditions 4X4 vehicles can be driven off-road at the same tyre pressure as on sealed roads. However, in low traction conditions (ie. Sand), it can be beneficial to slightly reduce pressure to achieve better grip.
- Load, speed and pressure are all interrelated.
- If you want to reduce your pressure whilst maintaining your load, you must reduce your speed.
- Always remember to reinflate your tyres to correct pressure immediately upon returning to sealed roads or high speed sections Off Road.
- Reduce your tyre pressure without reducing Load or Speed and you will have excessive heat built up in the tyre.
- Tyre pressures should be checked when cold at least every two weeks and always inflate after off-road use.
- Under inflation, which must be avoided for on road use may sometimes be required for specific off road use.
- Regularly rotating your vehicle’s tyres helps extend the life of the tyres and saves time and money in the long run.
- Inflate tyres according to the vehicle manufacturer’s recommendations.
- Inflation pressure in a tyre goes up (in warm weather) or down (in cold weather) 1 to 2 pounds for every 10 degrees of temperature change.
- Overloading the vehicle and tyre builds up excessive heat in the tyre and could result in failure.
- Visually inspect the tyres to make sure there are no nails or other embedded objects that could poke a hole in the tyre and cause an air leak.
- Proper alignment helps ensure that the vehicle handles correctly and helps increase the life and performance of your tyres.
- Regularly check if the tyre tread is worn out, if the shallowest groove in your tyre is less than 1.6mm you should look to have your tyres replaced.
- For best all-around performance, the same type of tyre should be used on all four wheel positions.
- Inflation information can be found in the vehicle owner’s manual, on the door jamb placard, located in the inside the fuel hatch or on the glove compartment door.
- Remember to check inflation pressure on the spare tyre.
- When replacing speed-rated tyres, you must use replacement tyres with ratings equal to or greater than those of the Original Equipment tyres if the speed capability is to be maintained. The handling of a performance vehicle may be different when the replacement tyres are not the same speed rating.
