The tips and tricks outlined below are applicable to driving in any sand, be it on the beach, in sand dunes, in the desert or in the forrest. Anywhere you come across soft sand, these techniques will be applicable. If you are driving on sand dunes, then please read the 4wd Tips and Tricks – Driving on Steep Terrain article as well. In particular, it is worth mentioning again, that you should NEVER drive across a steep hill, especially sand dunes. Doing so can have disastrous consequences. There is a serious and very real risk of rolling your vehicle all the way down to the bottom of the hill. Elements of Sand Driving
There are two elements to driving your four wheel drive on soft sand. These are:
1. Tyre Pressure
2. MomentumApplying these elements do your driving technique will result in your vehicle ‘floating’ on the sand, decreasing your chances of becoming bogged. Naturally there is no guarantee that you won’t bury yourself to the axles, but your chance of success is increased if you pay attention to these elements.
TYRE PRESSURE
Reducing your tyre pressure will spread the weight of your vehicle across a greater surface area, and increases the surface area of the tyre in contact with the ground and achieves two objectives: 1. Increases traction 2. Prevents the tyres from sinking into the sand quite as much.
There are many schools of thought on how much you should reduce your tyre pressure when driving on soft sand, but a guide would be to reduce your tyre pressure to half that of your normal road driving. If you find your engine struggling then reduce tyre pressure some more. You can try reducing in 4psi increments until you’re satisfied. Finding the right pressure for your vehicle and the current conditions can be a lot of trial and error.
MOMENTUM
Driving on soft sand can be compared to a speed boat on water. When the boat is travelling slowly, it sinks into the water a little and the engine is required to work harder to maintain forward momentum. As soon as the boat speeds up it starts to plane along on top of the water. The engine requires much less effort to push the boat along and the boat is able to quickly skim along the surface of the water. Similarly, driving slowly on soft sand will allow the tyres to sink into the sand much more than driving more quickly. When the tyres sink in a little, the engine must work much harder to maintain forward movement. As you increase your speed, your tyres will float on top of the soft sand much more, and the effort required to maintain your forward momentum will be greatly reduced.
Use low range initially. If you start to get bogged, low range will provide you with the power you need to drive out, but will also allow you adequate speed to keep you on top of the sand. If you decide that the beach is hard enough then you can change to high range. CAUTION: Do not overdo your speed. Driving on sand is nothing like driving on the road and driving quickly greatly increases the chance of serious accident.BOGGED
If you regularly drive on the sand, then eventually you’ll get bogged. Accept this fact and prepare for it and your day will be much more enjoyable.
When you do get bogged in soft sand there are a number of techniques to getting back out.Firstly, it’s important to realise early that you are bogged. There is no point in spinning your wheels. This just digs you in further and makes any recovery effort more difficult.
Don’t panic! The vast majority of the time, if your car stays bogged for a while then the only consequence is that you’re late to your campsite. So stay calm and take your time to think it though.
Reduce your tyre pressure even more than you already have. Remember that the more you reduce your tyre pressure the more your vehicle will ‘float’ on the sand.
Try to reverse out. Often the tracks you used to drive in are solid enough for you to drive out on. Then you can have another go or take a different route.
Slowly drive backwards and forwards over the same track. This compacts the sand and hopefully allows you to drive out.
If these tips don’t get you out then get your shovel out and start digging. Choose which direction you want to drive out and then dig out the sand in that direction. Don’t forget that you’ll need to clear the sand from underneath your axles and differentials as well. And if you’re bogged enough then you’ll also need to clear the sand away from your undercarriage as well.
Make a track for your wheels. You could try lining the track with dry seaweed (wet seaweed can be slippery), sticks, leaves etc. Anything to gain some traction.
Also, try something like Max Tracks. Static methods of recovery and those that don’t use other vehicles are much safer.
If these fail then get out your snatch strap if you have a travelling companion. Keep in mind that you don’t need to tear the car in half in order to pull someone out of the sand. Often a gentle ‘tow’ is enough.
Still bogged? Do you have a winch? If not then don’t give up, just do it all over again, but try harder.

Excellent post Amjed, considered advice in a calm neutral tone, perhaps it should also be made ‘compulsory’ for all members like signing the DO disclaimer!
