Tire Pressures - Off Road Recovery Tips
Of all the off road recovery tips this is the most important one to remember. The main thing you can do to avoid getting stuck is lower your tire pressures.
A few years ago a tourist couple got stuck in the Aussie outback. They couldn't get out of the sand and one of them perished walking for help.
The rescuers simply let some air out of the tires and drove the truck out.
So, get a tire pressure gauge and let your tires down a bit. The more air you let out, the more tire will be on the beach and the greater the flotation you will have on the fluid sand.
However, there is a risk to this strategy -particularly if you let out too much air. Under-inflated 4WD tires will be more likely to roll off the rim especially if you turn sharply.
For most 4x4 truck tires, 18 psi is a reasonable compromise, but you can go lower if you are stuck.
I often use 14 psi and have been as low as 6 psi on occasion. You should drive slowly and gently at lower pressures as an underinflated tire can come off a four wheel drive rim very easily. If you fit tubes into your tubeless 4x4 tires this will help keep them on the rim.
You will need to pump your tires up before doing any speed (greater than 30km/h), especially when you are back on the road. I carry a 12v air compressor to re-inflate the tires.
