Four wheel driving is a great way to relax and escape a hectic
city lifestyle, but before embarking on a journey, it is important to remember
that four-wheel drive vehicles are not the same as the average passenger car.
Most four-wheel drive (4WD) vehicles are bigger than the average
vehicle and have different handling and braking requirements. When driving a
4WD, you should be aware of their handling characteristics, both on and off the
road.
A 4WD does exactly as the name suggests - it transfers power to
all four wheels, allowing the vehicle to be driven on a variety of surfaces and
terrain with minimum slippage and maximum traction.
Different driving methods are required for different terrain. For
example, your driving approach in the snow would vary greatly to when driving
over rocky land or on a highway.
It is a good idea to take part in a four-wheel drive training
course which teaches driving techniques specifically for four wheel driving such
as recovery techniques.
Before tackling difficult off-road terrain, be familiar with your
vehicle's differential and front wheel hub locking mechanisms (if applicable). A
training course will give you the required knowledge.
Tyres play a large role in the performance of four-wheel drive
vehicles. There are a variety of tyre tread types available to suit different
conditions. Some have "flotation" characteristics for soft surfaces such as
sand, to stop the vehicle sinking, while others provide grip on loose surfaces.
When considering tyres, also think about how much travelling you
will actually do off-road. Your vehicle may be used a little for weekend
getaways, but if you spend the majority of your travelling time on highways and
sealed roads, your tyres must also be suitable for these conditions.
Tyres that have both on-road and off-road capabilities are
available. Discuss your options with a VACC Accredited Tyre Dealer.
Different terrain conditions might also require different tyre
pressures. For example, when travelling on soft dry sand, the tyre pressures
will need to be reduced for better flotation.
Make sure you always have a
suitable spare tyre and the appropriate tyre changing tools, including a
high-lift jack, tyre pump and lock nut adaptor, as well as a compass and
detailed map (and make sure you know how to use them). You should have a first
aid kit, and vehicle recovery equipment including a spade, winch and chains.
Be careful if using sealant to repair a puncture, as this type of
product is a temporary fix and should only be used in an emergency.
After a sealant is used, the wheel and tyre should be taken to the
nearest tyre specialist as soon as possible for inspection and quality
repair.
When four-wheel driving in difficult terrain, it is wise to travel
with another four-wheel drive vehicle so that you can help each other in tough
situations. Always make sure you let others know where you are going, giving an
approximate arrival time should you get into trouble.
Make sure your vehicle
is in good condition at all times. VACC has many members who specialise in the
maintenance of four wheel drives.
With the correct equipment and knowledge, and a well-maintained
vehicle, you can enjoy a relaxing time away with your four-wheel drive.
