How to: Dune driving?

Hi, time has come for our first dessert dune session in the auto 2012 jkus,

As I've never owned an auto before, how do I run this baby properly in the sand?

Do I turn traction control on or off?
Do I run it in 4 hi or 4 lo?

What gear? Just in drive? Or use the triptronic and leave it in first or second?

I don't have disconnects nor diff locks..

Also this is serious dunes as in the desert, not as in beach driving : )

Cheers for any tricks and tips you can give me, in return I'll post up a few pics.. : D

Air down, Air down! Make sure you have a way to air up(compressor or nearby gas station). That is the first and most important thing to do in soft sand. My only auto experience in the sand is with my Tacoma. I would run it in 4lo and the rear locker engaged.

the dune driving I've done required 4H and keep moving....sand conditions will dictate whether you bog down or float over the surface.

This is a general notion on deep sand: float rather than dig in

A suitable forward motion rather than creep mode

someone to tow/winch/drive you back to wherever the tow rig can access you

watch some videos, it comes pretty easily "how to" but there are always unexpected conditions which may/can/will affect your trip

flatter wetter sand is a good place to begin learning how to evaluate what technique to use

sometimes watching the local guys helps avoid getting stuck

if you haven't gotten stuck at least once you haven't really been Jeeping

steepness of dunes and firmness of the sand compaction must be considered

it doesn't take much to be swallowed up in loose sand

once you sink and your wheels spin if there's no traction you better already have Plan B as walking/towing is involved....digging in mounds of loose sand isn't a lot of fun

local conditions for sand in such as the high desert vs beach sand varies widely

Funny thing is, 95% beach driving can be done in 2Hi. I normally only use 4 Hi for the very soft, wet flaky stuff.

Tires-tires-tires-tires, the most important part-

Angle of the dune/sand consistancy and wheel spin, but

If you have a shovel and winch/comealong/land anchor-or

These-





You can survive alone, although you shouldn't be !

Have to air way down. When I went to Silver Lake in Michigan, floor it going up the sand dunes, if you don't you will stop. Once you get near the peak, let off, you can even stop then, it will be ok. You don't want to go flying off the other side of the sand dune. Wind during the day can change the angle on the other side. Start by going down the dune slow until you get the hang of it. But I always slow down at the peak. If you get bogged down going up the hill reverse down the dune, more than likely you'll be ok to try again.

Sounds like good advise , how far down do I air the tires? I am running Mickey Tomsons 33" and then back up on the hard stuff, how much should they have in them?

Also, what's the consensus on traction control on or off?

Cheers

I haven't been to Dubai, but it sounds like a place with a lot of dunes. There should be a plentiful supply of accomplished dune drivers around. I would assume you would set your JKUS up like a dune buggy - fat, low-pressure tires and some sort of onboard air for when you return to hardtop. Try to find some other Jeepers to go out with.

And then YOU can tell US all about driving in the shifting dunes. Enjoy

I live in UAE too, i usually drive on 4H with traction control switched off.

I Air down the tires between 8 - 13, it depends on the trip difficulty

Also in dubai here, haven't gone out into the dunes yet, waiting until I slap on some 33/12.50 before I go to make up for complete lack of desert driving knowledge

No dunes here in the Southern NJ Pinelands; however, I did pay attention to this thread and attempted to "float" across some of the deeper sand crossings by keeping my speed a little higher, and I have to say it was very effective!
Speed wasn't so high that things were jouncing around hard. It actually felt more like floating.

I was taking it a little slower previously and letting her kinda work though it, but this way was much better.

I really learn a lot from this place.
Thank you!

As a mere "antiquated" '08 JKUR owner-

Nothing I could say would have any merit !

You should turn traction control off in sand. See daggo's post (#11) in thread below for how to do it:

Traction control ?


Some other links you may find useful.

I'm jealous. Never done any desert driving. Have fun!
