With All Terrain tires, I find that 15~16 psi is low enough for soft sand.

The reason why soft sand puts the gearbox under extra strain and may cause it to get too hot in 4High, is that the tires sink and pile sand in front of them -- this is resistance that the gearbox has to overcome. This generates heat.
In order to roll forward, they have to constantly climb the sand pile in front -- which is yet more resistance for the gearbox. This generates more heat.
In 4Low, the gear ratio means less effort, so less heat is generated.

what kind of air compressor would you guys recommend? , also thank you so much for all the help!

Avoid the cheap, "walmart special" compressors, they don't have the ooophh, and get one that draws power directly from the battery using alligator clips, not plugs into the cig lighter. Despite Smittybilt's less than stellar reputation, this one has served us very well for 4+ years :

Smittybilt Q89 Dual Cylinder Compressor. Sold at a number of places, eg http://bumpersuperstore.com/i-115749...FYM8gQodmV8AVg

Fills the 35s of the Jeep and 38s on the Bronco.

The superflow mv50 works really well and be bought at Oriellys for about 60 bucks I think, might have been less, had it a long time and works great on my 35s.

Air down to 10-12 PSI, maintain your speed. Stay smooth on your throttle AND brakes. No abrupt acceleration, braking, or steering. I'm on stock Rubi wheels/tires and can go just about anywhere in Pismo beach dunes in 2 wheel drive. Only a few hills require 4 hi to climb. On sand, speed is your friend. Stop only on flat or decline hill. Parking on an incline is no good, you'll have to reverse out of it. Get out there, try it, and have fun. You'll love it.

No, I would mob at the beach in my 2WD Dodge Ram just by airing down the tires. The few times I got stuck, all we did was dig some sand out from in front of the tires by hand and that was enough to get her going again. Pismo Beach Dunes State Park is pretty much my back yard and I have never seen anyone use traction boards. A little bit of digging does wonders. Sand driving is really not as bad as it might seem. Super fun.

I've had great results w/ the ARB high volume unit mounted in the engine bay (mount uses master cyl bolts) - it airs up my 35s from 15 to 26 in about 30-40 sec per tire.

Hey there just got my 2015 rubi and plan on going on the beach. You say your on stock tires that sounds great to me ! Just had a lot of people tell me they would be no good in sand to aggressive. But happy to hear you had no trouble I would be bummed if I needed to buy more tires.
