If you could only do one upgrade to your 4WD to increase its ability to negotiate tough offroad situations, the addition of a set of quality all terrain or mud terrain tyres would be the way to go.

TYRE PRESSURE GUIDE



Effect of adjusting tyre pressures on the size of a tyre’s footprint
This diagram illustrates the effect of reducing your tyre pressures on the size of the footprint of your tyres. Reducing pressures and increasing the size of your tyres footprint spreads the weight of your vehicle over a larger area so when driving on sand, for example, your tyres will drive ‘over the top’ of the sand. If you maintain high pressures and a small footprint, your tyres are more likely to ‘dig down’ into the sand and even get you stuck! Remember, whenever you reduce your pressures, re-inflate to the proper levels as soon as you drive back on to the bitumen.
