woaw ... awesome more info please??

 

I just spent a week on the beach and sand dunes north of Corolla on the Outer Banks of North Carolina. Aired down to 15 psi with 5 adults in my JKU and never had a problem. Even pulled out a poor soul in an AWD Kia. Airing down is key as already stated by a previous poster.

 

Things felt great out in the sand. I fully extended my suspension once or twice, and had a great time, but when I got back on pavement the steering was really jerky and the tires scrubbed and barked on the parking lot.

I thought maybe I was stuck in 4WD, so I shifted in and out a few times and drove a tight figure eight a few times.

That seemed to fix the steering hitch, but as I turned into the gas station (20 miles later) to air up, the tires wanted to scrub again.

I have never felt that, and I've driven on pavement at about 18psi after crawling or running trails.

Once I aired back up to 30psi all the weirdness went away.

Any thoughts? Could my $1.99 tire pressure gauge be misleading me?

 

I ran a multi wire cable from the battery to the p side tail light ,
then made a plate to mount on the tire carrier ,
you have to remove the pressure gage thats on the compressor ( 1/4 " brass plug I think I did it 3 years
ago and I'm old ) had to file and test fit a few times .
I have stock 17" wheels
When i got the ORFAB tire carrier made a plat and used the mounting points of the stock tire carrier ,
You might want to cover it for the winter, I don't but it doesn't freeze here ,
and the fuse holder on it is a POS remove it and put one at the batt.
the air coupler in pic #2 is for a flag antenna a must for the dunes out here.

and invest in a deflater its worth it http://www.4wheelparts.com/search.aspx?kw=deflator

 

I just did a sand dunes trip this weekend aired down to 15 psi. I have a Sahara hard top unlimited with ARB front, roof top tent, nitto trail grappler 295/70r18 and 4 adults on board with no cargo (left it all in the camp site) and did really good. I went also with 2 stock jk 2dr and 4 dr, a fully equipped Tacoma, a med equipped fj and 2 land rover discovery

 

Maybe I'll go lower next time. I'm scared to break a bead, but I guess I'd be okay down to 10 psi, right?

 

I've done 10 to 8psi just fine with 35's without bead locks several times rock crawling with no problems. You definitely have to watch your lines but you should be just fine. 10psi should be good for you.

 

When aired down low in the sand (under 12 psi) without bead locks make sure you are not going into a turn at higher speeds and sliding you tires sideways and you will be fine.

We use bead locks on our sand rails as we are going into a turn at 40 mph and sliding sideways until you get forward bight on the paddles.

When I take my Jeep or pick up in the sand I air down. 10 psi for my 2DR Rubicon Jeep (weighs about 4800 #s) and 15 psi for the 1 ton 4DR long bed Dodge diesel PU. (weighs about 7200#s)

I don't usually 'dune' with the Jeep or PU, as I have better vehicles for that, but sometimes a recovery is needed....

 

Thanks, guys. I'll air way down and remember I have a spare if I roll a tire off the wheel!

 

You could douche the electronics with Rustoleum Neverwet. I saw a video of it being sprayed on the internals of an iPhone, although I can't find it for the life of me now. But that should keep it from shorting out from winter and driving in water and rain.
