A couple of years ago I paid a sand dune tour. The company used Toyota Tacoma's, and the drivers were sand bosses. I've had nowhere near the same luck in sand using my jeep. But the jeep has to be a much more capable vehicle than a Tacoma, right? To tell the truth, I've never let the air out of my tires like they did because I've never travelled with an air compressor, and I didn't know how low to go.
I read on an older thread that 10-15 psi in the tires works great. That seems low to me. Any idea if there's a threat of the tire bead becoming unseated?
What about refilling the tires? Is there a nice compact portable air compressor you can recommend? I drive four hours south from my house to southern Utah. My trips usually involve camping, and I would rather avoid an air compressor that takes up half of the Jeep. I don't want to wait four hours to fill my tires back up, either.
In remote areas my jeep has done decently in the sand, but there is the occasional paranoid sinking feeling. It would be a long walk out if I sink up to my rails. I'd like to do some dune driving. I have to think there's a way to do sand driving better than what I've been doing.
Welcome to Jeepforum, Check out the Utah section under the Fourwheeling neighbor hood in the southwest subsection. We have a bunch of Utahn's whom are very active on here.

I personally run 12psi on 10.50" wide tires on 15x8's when I go wheeling. With the other rigs I have owned I ran 8-10 Psi with 12.50" wide tires on 8" wide wheels. I have never lost a bead.
When I lived back east I did drive on the beach alot in the summer months I will say that 12 PSI always felt nice aslong as you dont make a sharp turns you should not loose a bead .
Asfar as compressors go I run a Smittybilt 2780 compressor I had to replace one after 4 years of service my new one is about a year old now still working great. But they do get hot For anything over 35's I would not recommend this one I would Lean towards a Powertank or a bigger compressor like the 2781
They are correct. When driving on sand you want the largest possible footprint without loosing the bead. Airing down will increase the contact patch and help give better traction. You will want to take corners at a lower speed when aired down so you don't break the bead loose.

Work with enthusiasm as though you were working for the Lord rather than for man.
Smittybilt has some cheap deflators for about $35 and I use them all the time. Those that sit there with their gauge eventually ask me to use them and I comply. If you air down three times a year, its worth the money to buy them. They have to be preset at home before they can be used on the fly but once they're set they are golden. As for airing up, there are several different electric compressors that start at about $40 and go up from there. It isn't a race to get your tires aired up but it sure is nice to have it done quickly. I took an electric compressor and hardware e and hard mounted it into the jeep and it seems to be the one everyone uses when they get bored of standing there holding their cheap compressor's air chuck for fifteen minutes.
Pick up a big box four wheel drive outfitter's catalog and take a peek inside. There are several goodies condusive to your wheeling experiences.
I was out in UAE in a rented Toyota Fortuner, I sank like a rock with street pressure, brought them down to 10 PSI on stock street tires and didn't have a problem. I wanted to see what the difference was after watching some youtube videos on it. One guy in a land cruiser said dropping it down to 10 PSI will give you half again as big a ground patch as regular pressure. I was flying over the very loose stuff. Call a friend that can get you out and try different pressures. It will teach you a lot.
