Tire pressure in sand?

Tried searching but apparently all the keywords are too common so the search kept excluding them.

Looking to do a bunch of beach driving in remote locations and will need to air down. What pressure do yall air down to? At what pressure to the factory tires really get problematic with de-beading? Im thinking 20 psi, that will keep plenty of force on the beads but still allow the contact patch to grow quite a bit but Im sure somebody has some experience.

Having done a ton of beach (see my pic in the July truck of the month thread for proof) driving unless you are in the super dry loose dune sand you don’t need to worry about it, anywhere that is even occasionally wetted by the tide will have a firm layer a few inches down and four wheel drive will be enough (assuming you have at least AT tires and not street tread).

Be sure to turn traction control off as a little wheel spin actually helps keep up your forward momentum and activate the rear locker. If you must air down I wouldn’t go below 20 on anything without a bead lock, and you still risk knocking the bead off on driftwood / holes.

Ive got the factory all terrain wranglers. Mine is the crew cab 6.5 foot bed with a full ARE camper shell, leather, etc so its heavy already and I wont necessarily have the option to choose the sand conditions. The good thing is that previously I had a 97 suburban z71 and loved running dunes in it so ive got plenty of experience with a heavy vehicle with high ground pressure in sand. That said, its still a bad combo lol.
