Oooh 5 psi without bead lockers is pushing it eh? (hmm maybe in sand, not so much unexpected side wall pressure??)
I didn't stop until I was back across the railway line and both tyres looked flat but there was enough air to keep them in place. I didn't measure the pressure but I kept deflating until there was a very slow airflow. It was that or be prepared to spend the night on a backtrack and face the heat tomorrow. It's amazing how much difference tyre pressure makes in soft sand. I've had to do a similar thing before in a LandCruiser on standard skinnys on the beach. Any reduction in pressure helps but it's that last few pounds that really makes the difference of whether you stay there or get out. You often find damp sand down a bit but that stuff yesterday was dry and loose as far as my tyres dug and it doesn't help when you have a ladder frame engine and transmission protector that is only 200mm off the ground when the tyres are inflated.
Check out the length of that roadtrain in the photo above. They seem to get bigger and bigger.
