Sand Driving
Sand driving isn't particularly difficult as long as you obey some basic rules:
* Always carry a good quality air compressor. The cheaper variety ($70) from your regular car accessory shop is not adequate. These models usually run off the cigarette lighter plug and quickly burn out. Remember it takes about 30mins to inflate all 4 tyres after sand driving to acceptable levels for driving on bitumen. These compressors are only designed to inflate one tyre at a time (handy for a slow leak). The larger capacity air compressors enable tyres to be inflated continuously without overheating and usually in half the time.
* Don't be afraid to deflate your tyres (you can go down to 10psi without damage in soft sand if you absolutely have to)
* Never drive over 60km/hr on deflated tyres
* Inflate tyres as soon as you pass the soft sections to prolong the life of your tyres
* Avoid driving deflated tyres on bitumen (if you have to, keep speed to under 50km/hr).
If you get stuck in sand, firstly check that you have engaged your hubs and are in 4WD. Once stopped, first try reversing over your tracks. If you cannot get out of the bog in reverse in one try, get out and deflate tyres more. Check that the diff is clear - usually by now it is deep in the sand and you'll need to dig it out with a long-handled spade. If the sand is particularly soft it sometimes helps to clear 4 tracks - one for each tyre. This is also a good method for reversing out of a bog.
Select a gear that will get you out of the bog without digging yourself in further. Try H2. Give it some revs to get out of the bog and onto a firmer patch.
When driving on beaches never park on the wet section of sand. Vehicles have been known to sink into the sand and slip into the sea. Always park your vehicle with the nose pointing to the sea and if doing a u-turn always drive towards the waterline so that the turning tyres are in firmer sand than if you turned with the vehicle positioned nose uphill where the weight of the vehicle would weigh down the driving wheels in the soft sand. If you're having troubles driving along the beach (parallel to the water line) and find the vehicle is wanting to slip sideways (usually rear to the water), point your wheels to the sea slightly instead of away - its the rear of these heavy vehicles that wants to slip down the slope and doing so will give the vehicle a chance to get enough momentum up to get out of trouble.
ALWAYS carry a tide chart for the beach that you are travelling along and try to travel at low tide.
Sand Driving at Stockton Tips
* In the carpark it is best to deflate your tyres for sand driving - start by deflating to at least 20psi and depending on your vehicle and how you're going, consider letting out a bit more air if you have troubles.
* Provided you don't turn too sharply with soft tyres you shouldn't have any problems going as low as 12psi.
* Ensure you have a good heavy duty air compressor to inflate your tyres back in the carpark at the end of the day (no compressor provided). The other option is to inflate your tyres at the service station in Anna Bay.
* Always drive straight down the dunes, driving at an angle may cause your vehicle to roll over
* Never use your brakes descending a sand dune, in fact it is best to use the accelerator a little
* Never stop your vehicle half-way down a dune or side-on at the top of a dune - soft sand may fall away from under the weight of your vehicle causing you to roll over
* Only one vehicle per dune at a time
* Never come up behind a vehicle climbing a dune
* If you get stuck going up a dune, reverse, don't roll and try again
* Never turn on the face of a dune |
