ratchettt I am fairly new to airing down too. I can tell you the expert Trail Guides with Jeep Jamboree Tennessee Mountains this past weekend ALL agreed it was fine to air down to 16-18-20 and go 15 to 20 miles on pavement. Just keep speed down around 45mph. They had us air down before the drive to the OHV park.

I have elected since getting back to buy a portable compressor for peace of mind when a coin operated compressor is unavailable, at great distance, or the line is too long. Decided to get one with enough capacity to air-up friends as well. You no longer need to permanently install a unit under the hood. Check Viair products.

dale 3 Couple pointers to ease drivetrain:Let vehicle roll to a stop.Slamming brakes dig holes.Holes may cause wheels to hop out of stuck.Hopping is bad.Wet sand and surf add's onto corrosion.Always start moving from a stop wheels straight.It's a fine if not aired down on the beach i travel.Every time i leave beach vehicle gets a complete rince,inside frame holes too.Then driven to dry.It's a whole other feel in sand.You'll figure it out with practice.Keep your rpm's up.Easy to lug your engine.Lugging is bad.

dabolt55 I have this and it's been great for the value. Hooks to the battery instead of cig. lighter. Good luck to you and enjoy the beach...Q Industries MV50 SuperFlow High-Volume 12-Volt Air Compressor : Amazon.com : Automotive
Plus air down to your likings and no worries of airing back up.

I use a combination of High range and low range throughout the day. On the flat beach, high range is fine. As far as air, get a cheapy air compressor from Harbor Freight and then get the tires back up to about 20 psi before your drive to the air station.
Thank you for the insight on tire pressure. I kind of had a feeling that 25 psi wouldn't make enough of a difference. I also like your idea of airing up at least part way before venturing to an air station. Also, sweet pics thanks for sharing!

Now just to clarify everyone, I'm not looking for performance here. You guys are clearly much more experienced with much more extreme conditions than I am. For beach use, I am planning on driving <1 mile. It might be 2 miles, depending on the day, to our beach spot. Putting out a couple of chairs, spending some quality time with the ocean. Maybe taking a trip into town for lunch at <25 mph and coming back onto the beach for the afternoon.
I mean, I feel like a wimp downplaying what I'm trying to do here.

I'm not familiar with that state park. I'll have to check it out! The family generally meets up in Brigantine. It's in southern jersey, near Atlantic city. They sell permits to drive onto one part of the beach. It's nice because it's somewhat exclusive (by the use of permits, people either don't have a vehicle or don't want to pay the $120 or whatever it is that year). People drive up their vehicles and that's kind of your plot for the day. Nobody on top of each other like walk-on beaches. You can walk up and down, chat with your "neighbors," haha.
I'd say the sand there is definitely on the soft side.

Rayko The beach in Jersey is nothing like your pics. There are dunes but they're off limits to vehicles. Hell they're even off limits to walk on. Most of the driving is soft sand, the firmer stuff is usually full of parked 4x4's surf fishing. I find 18 to 20 lbs to be good. The air stations are in the park and not far from where you exit the beach.

Rayko Getting stuck close to the water on the incoming tide can be very nerve wracking

Y-Guy I hit the beach in Oregon earlier in the month, I did a minimal air down to about 25 and cruised between the soft and wet sand in 4L and had no issues at all, the Jeep crawled right through the sand just fine. On the way out I put in 4H and did just as well, that said if you're near any wet sand I'd stick to 4L as getting in to 4L without moving can be a challenge (been there done that on my first attempt) and getting stuck around the ocean is bad (m'kay).

Questions about beach driving

The jeep I've recently acquired is a '13 JK sport, 2 door soft top automatic. She's all stock.

Brand new member here. (Quite a newb, go easy! ) I have searched the entire forum's history for all beach driving related threads and read at least 90% of all the posts. I have learned a lot but there is some conflicting information. I write this post because I think my situation might be a bit different than what has already been discussed. Basically, I think how I want to use my Jeep on the beach to be light duty.

Here is my own summary of what I've read about airing down:
Air down should be directly proportional to dryness/softness/deep was of sand at least 20 psi or lower, maybe 15 or lower depending on tires. However, many report not needing to air down much if at all. I understand this will dig deeper ruts in the sand which isn't nice, inconsiderate, and run the risk of getting stuck.

The way I plan my beach use of the Jeep is not prolonged at all. It will be New Jersey sand which I understand is typically less soft. Perhaps a 5 minute ride on sand (maximum time) from the entrance for 4WD's to where we park near the surf. Occasional trips into town for lunch, etc. I don't plan on any extended driving on the sand.

So that leads to my questions about the way I intend to beach drive as illustrated above:

1) Do you think I can get away with only minimally airing down for a short beach drive? Say to 25 psi? 20 psi? (Stock tires)
Follow up question: how far and at what max speed to find a gas station without a line at the air pump? (Have been highly considering getting an air pump, but the wife is frowning on too many accessories for now haha).

2) Considering my automatic transmission, 4H or 4L for a short drive onto the beach? Think with a short drive I'll be relatively safe from the dreaded "hot oil" light while in 4H? From what I've read, it seems like the consensus is 4L is for very deep, soft sand, or for to try to get yourself unstuck. I think I answered this one for myself with 4H but would like to poll the community anyway. And how does 4L keep things cooler anyway? I'd really like to just use 4H because it'd be easier to get into and out of for a newby like me.

3) I've read on other threads about a) the benefit of turning off ESC for 4H and b) partial off versus full off (hold for 5 seconds for full off) I should definitely turn ESC all the way off, right? I've seen the difference of partial off and full off explained but I don't quite understand the appropriate setting for each to be used. I also understand that in 4L it is fully off by default.

Thanks to those who read and reply, I greatly appreciate any advice.
