I've just moved to Saudi, and will be expected to drive in the desert
for some distance to reach remote oil installations. What is the
group's sand driving advice ? Should I be in 4WD or 2WD ? I'm driving
a Toyota Landcruiser 2002 model.

Cheers,

Blewyn

Last time I was there, at first - we just watched the locals. Note the
type of surface they drive on, and the types they avoid. Saw the
most amazing pieces of 2wd junk cruising out there, barely leaving
any tracks at all. Seemed that most of the ground was pretty solid.
Another rule of thumb was that if the sand was too soft to walk
on (ankle deep or deeper), wait for some other fool to drive on it.
First time I stuck a floatation-tire'd military jeep, I found that the
sand was mid-calf deep dust/powder, and the walk-out damn
near killed me.

I have some info on sand driving below:

4WD and air the tires down.

8-16 psi should do, make sure you have a tire pump in the truck, so when you
get back to the solid road you can inflate them back to road pressure.

what you're looking for is a big footprint, big wide tires aired down to
10 or 15 psi, and whatever you do, don't EVER spin your wheels.

Or try to turn sharply, which can also cause the tires to bury
themselves.

Thanks for the advice guys ! One question remains though :

4WD or 2WD ?

I would have thought 4WD, but my boss insists you should stick to 2WD
as it will make the front wheels less likely to skid on corners (the
tracks to the rigs are sandy but fairly compacted, not fresh windblown
sand). Some of the corners are quite rutted.

What do you think ?

Cheers,

Blewyn

Dusty gravel roads here I use 4wd. same on the beach access track I use to
pick up sand for concrete. But then, I'm not where you are, ask around
veteran local sand drivers. especially ask locals born in the area who drive
there all the time.

For sand driving it's best to have fairly low amounts of tread, more tread
just makes it more likely to dig holes than skim across the surface.

And if you can, get a set of Michelin XS Sahara tyres fitted - they are
specialist sand tyres and their advantage over normal tyres has to be seen
to be believed.

Your boss knows what he is talking about.

Even in the city on snow covered streets, dropping to 2 wheel drive when
turning at an intersection makes the turn much easier.

When in 4 wd, one tire has to scuff going around a corner, this can make
the tire get up on top and just slide straight.

Well, first of all a Lancruiser is full time 4WD, theve come like that for
at least the last 10 years. The option u have is to lock the center diff or
not. U can leave it unlocked untill u get stuck. Nissan Patrol's have the
option of being in 2WD or 4WD. I'd recommend the new 4.8 liter 5 speed auto
combo for sand. However it's not really an option since u already said u
have a Cruiser...

Hi Blewyn,

Are you bragging or complaining?

Your best option is 4x4 at all times, HR or LR depending on the terrain.

Albert,

It's not a complaint because it's quite good fun to drive in the
desert.....and it's not a brag because, well, it's hardly worth
bragging about. LOTS of people over here drive on sand every day...

Blewyn
 
Not so. My Landcruiser has both a 2wd-4wd stick shift AND a a centre
diff lock switch. And it states quite clearly in the manual that the
vehicle is to be driven in two-wheel drive when on dry road.

Good point Mike, but don't 4WD vehicles generally have a diff on the
axles to prevent this scuffing ? (when unlocked)

He's not talking so much about the two front wheels turnign at different
speeds, as the front wheels as a pair turning at different speeds to the
rear wheels. A 2WD/4WD with a selection lever has a fixed transfer case
where power is split fixedly at 50/50 front and rear, with front and rear
wheels turning at the same number of revolutions. but when turning a corner,
the front wheels have less distance to cover than the rear, yet the fixed
transfer case makes them turn the same number of times as the rear wheels,
hence the scuffing.
Permanent 4WD vehicles with a center diff are able to reconcile the front
and rear wheels turn when cornering.

Yes they have a diff, but when in 'part time' 4x4 the front and rear
axles are locked together. This make for a tire having to scuff.

If you have an open diff between the front and rear axles, then if you
leave it open, you won't have scuffing issues.

I drive Jeeps that lock solid into 4x4, no center diff, so I always have
a scuff in 4x4 when turning even with my 'open' diff axles.

You mean the front wheels have MORE distance to cover, right ?

The next time you drive round a corner making tracks that can be seen, hop
out and walk back, you will see the front wheels tracks are inside the rear
wheel tracks, covering less distance than the rear.

The front wheels have to turn round fewer times to corner than the rear
wheels which are being sent around the long route.

No, you have it backwards. The front wheels travel farther than the rear
wheels, they are the outside tracks, the rear wheels are the inside tracks.
Next time stop half way through your turn and look at how the vehicle is
sitting.
