If you lower the pressure a lot, when it is hot, then over night the air cools and the pressure drops more! Why you may have flat(ter) tires in the
morning!

I noticed that nobody mentioned "low pressure" alarms going off? Our '05 Explorer has more "idiot" light/alarms than you can shake a stick at and
tire pressure is one of them. I have sort of given up trying to lower the air pressure for the portion of a washboard road that we live on and just
suffer.

I am running load range Es and I am wondering how LOW I can GO, if I got in a real fix? Soft sand is the fix I'm talking about.

Hi hook. Those were e rated tires and no problem right in front of my casa. My newest f350 has 20's haven't put it on the beach
yet.
Haven't had a bad trip yet....

So, David, that 75% you are recommending is from the rated full inflation, I assume?
I'm headed to the dunes today. Not going to try any hill climbs in the F350, just some fairly deep, soft sand. I'll bring the wife, the Wrangler and a
tow strap, just in case.

If you air down and rub your street tire sidewalls against sharp rocks, this is what you get.
sidewall protection is muy importante!

80 psi is what you posted, so if you drop 75% (60) that puts you at 20 psi. It is where I would go if it was my truck... unless the sidewall buldge is
enough at a higher pressure. Then if you are not moving with ease, as in the video above, drop more. This pressure rule is for DEEP SAND, not
washboard roads.... that would be mabe 50% on your heavy tires, or 40 psi vs. 80.

Anyone have any experience with dualies on soft sand? Have always wanted to take the moho to Pismo and Baja but would hate to get it stuck.

Well, judging by how many MoHo's we in the BLM use to haul out of the Imperial Dunes each major weekend (even in the campgrounds) I would say they
don't do very well, just as semi-trucks don't do well on sand--------way too heavy, I am thinking. In sand you need to "float".

I went through some very deep sand in my old Jamboree 24 with duallys. I did air way down to between 15-20 psi. This was in Vallecito Creek where Bow
Willow Wash converges with it.
I did NOT stop, however. Too afraid!!!

YES... Art does (edm-1)!
Here was still too much air, even with 4WD and lockers front and rear:
Here is once enough air was removed... like night and day!:

Those are the same michelins that came with my Tundra. I blew out those three tires, all within 2 minutes last year. Never again....
