Once upon a time you could get a CJ with 9:00x 13 sand tires.

In reply to Mazdax605:
I used to inflate my truck's tyres to 35 Psi cold. I never worked out what they went to when they got warm. Anyway, I had a set of Staun tyre deflators set at about 16 Psi, and I used to just go directly to that setting from warm prior to driving on our beach. You don't need to worry too much about rolling the tyre off the bead at the speed unless you do a really crazy turn. And given the tyres are flexing so much, they get warm again fast anyway. 16 Psi is generally more than enough, and you are right to not want to drive for miles at lower pressures like that, so try deflating them to somewhere between 20-25 Psi and see how that goes. I've never even considered the cold vs hot pressure scenario to be honest.
Guess I've been doing it wrong all along. I've never aired down my tires (70psi E load range) on soft sand. I just stick it in 4Low and crawl my way across, This is also in a 6k lbs 1/2 ton pickup.
Some of it depends on the sand where you are and how careful you drive. Some beaches are rather solid and easy to drive on and being conscious of what you are doing goes a long way to not getting stuck. The guidelines and rules help make sure that the beach patrol shouldn't have to spend a lot of time recovering Dad's SUV before the tide swallows it after his inexperience sinks it.
This sand is really soft like powder, and deep. I have only been using 4wd high so far, should I be using low range? Can you tell I'm new to this?
Use 4lo if the engine isn't getting enough torque to the wheels to turn them over. If you are bouncing along and have plenty of power don't worry about it and just stick with 4hi.
If you have a newer vehicle, you will have to contend with the TPMS light being on if you air down.
Yeah I'd stick to 4-high, 4-low makes it easier to get wheelspin.

The solution to this is to put your TPMS sensors in a pressurized length of PVC and store it in the trunk.

A small price to pay to be out on the beach.
