According to my (1998) handbook "DO NOT use snowchains - they may damage
the vehicle".

Official 2007 Defender accessories - snowchains available and can be
fitted front and rear.

So what changed?

Go to Switzerland and it's a legal requirement to carry them.

Chances are that all that changed was that Land Rover started selling
studded tyres...

The original Handbook for my 90 says...

"Snow Chains.
Chains may be fitted to provide increased traction during extremely adverse
heavy snow conditions. Never fit chains to one wheel only, always fit snow
chains in pairs to the rear axle only, and ensure the gearbox differential
control is in the LOCKED position.
Remove the snow chains immediately the road is clear of snow."

So it was OK in 1986.

Interesting

Mine is a V8 with auto gearbox but I cannot see what difference that
makes. The tyre sizes are included in the 2007 approved list also.

They now also suggest fitting them to the front axle first, but also add
that you can also fit them to the rear. No mention of the diff being
locked.
Maybe you had a different kind of snow in '86

The diff being locked is highlighted in capitals in the "86" Handbook just
as I wrote.
Wonder why when it's not mentioned now?

Is it not a good idea to use chains on the hard packed snow that builds up
on untreated roads? I have no experience of chains but these are the roads I
find least traction on.

I've just checked my 1996 handbook and, in essence, it makes the following
points

Only fit approved LR chains to the front to avoid damage to brake components

Fit unapproved chains to rear wheels only

Engage Diff Lock

Not available for 265/75 tyres

Never exceed 30 MPH

These all seem pretty common sense I guess

Putting 2 and 2 together and coming up with

By 96 (latest) reports of damage to brake components at the front so

Does anyone know what the army does?

Or the Royal Marines MWC who are the real experts?

Fuck me, don't they have schools round your way?

They have these men & they give them guns, they call them soldiers...they
send these hapless blokes into someone elses country for no real reason &
whist some of them shoot at folk, quite a few get maimed & killed for the
good of mankind (or oil)

Easy.

So the reason my 86 Handbook says snow chains on the rear only is because
there weren't any then that fitted the front without a chance of brake
damage, and with them only on the rear you would need the diff locked.

I'm only surmising, but you could be right. It would make sense.
As I'm not quoting from an 07 handbook but merely the accessories list
it could be the advice is still to lock the diff - just as it is for any
off-tarmac driving. So from that point of view it would apply whether
the chains are on the front, rear or both.

If you have chains on the rear only and don't lock the diff, a front
wheel will spin and you're going nowhere.

The reverse argument applies if you have chains on the front only, of
course.

You should be on the stage...

Any stage.

But preferably the stage coach out of town...

If it's deep enough, like a couple of inches, may be. But generally
speaking we don't get enough snow in this country to warrant the use
of chains on road. If you are driving across a field to go and feed
and dig your sheep out that is another matter.

Tyres vary a lot. The things that came with the current DII are
bloody useless in snow, infact they aren't very nice when it's cold
(<5C) and wet. The old DII had Pirelli STR's they weren't bad I'm
going to get some proper winter tyres soon, probably Vredestien
Wintrac, as I really don't want to spend another winter on the
current things.

Just occurred to me - your 86 will have drum brakes on the rear whereas
mine has discs all round. Don't know when this configuration was first
introduced. So if the issue is disc brakes have they redesigned the
brakes to cope with chains or have they redesigned the chains to avoid
damaging disc brakes? If the latter then retrospective use would
presumably be OK

Yes that's correct, so it is probably the disc brakes that are the problem.

I have been wondering about this same subject. Couldn't there be a
safety issue also?

I mean, consider you are going downhill on a snowcovered road.What would
happen if you have the snowchains on the frontwheels and you break?

I would think there is a risk that the rear end would overtake the front
and your vehicle would come about and suddenly you would loose control
of the car. If the front have some level of traction due to the
snowchains whereas the rear might have none at all. If there is a slight
difference in the traction on the frontwheels I would think the car
would loose stabilty and therefor you would loose control.
Going uphill with the chains on the back might pose a similar problem
though. But since you are going uphill you have a better chance of
stopping and save the situation if things are about to go wrong.

I would consider putting the chains on the back wheels would be the
lesser of the two evils from a safety point of view, when not being able
to wear chains on all four wheels.
Does that sound completely off?
I'm just thinking here. I don't have any experience with it.
