Not starting an argument, but I've driven the whole thing many times just puttsing along at only a few mph with no problems no bumping or over heating and never even bogged down at all
Air down to 20 lbs when you get to the beach, use common sense while traveling between the villages then air up when you get ready to leave. Been doing this for 20+ years driving heavy Suburbans and (knock on wood) never had trouble.
So I have a question for everyone to consider since this topic has gone into ruts and maintaining drivability of on the beaches. The FF approach specifically seems to get very deep tracks going from everyone driving in the same track, fully aired tires making it all that much worse from what I understand. Is it better to just follow the ruts or is it better to get on the high stuff and push the sand back into the ruts? I am very new to beach driving so maybe I'm asking a dumb question. I run a Cherokee with 12.5's as well so even at 20 lbs I still get almost no "squish" to my tires but I am pretty sure it does help by not displacing as much sand as it would at a normal pressure.
My jeep does well out of the rutt where my ford rides better in them I think that depends on the vehicle.
The principle behind airing down is to make a bigger footprint.......ie floating on top of the sand by deflating........check out this video
Nice video, Thanks. I have been playing around with running my Jeep at 20 psi all the time and even with a few trips up to Wilmington have not had any problems with just leaving them there. Might try lower yet for the sand to see if it makes driving even easier but then I'd have to air up before heading anywhere very far. I like it at 20 because it isn't my daily driver but if my wife jumps in it I don't have to worry that I've left it sitting unsafe for her to drive a little.
I go to 20 when I get there and reinflate when I go home
