That is because of the different diameters of the old and worn tyres.
Trying to minimise the amount of work the diffs have to do to avoid
transmission wind up.

You want the grip behind you, not in front. Have the good tyres on the
front and in marginal conditions the back will loose grip and the
front won't. Having better tyres on the front of my old Mondeo (front
wheel drive only...) I feel was a major contributory factor in hitting
a wall and rolling over. TBH I'm not sure how this applies to a 4WD
However when I first got the Disco II, it was rather vague and
wandered about the road very disturbingly, when under light throttle
conditions and slightly down hill. It had the less worn tyres on the
front. I did nothing other than swap front/back and the vagueness
completely disappeared, noticable within in the first 100yds of
driving it was that marked.
Unfortunately there is another variable in that the pairs of tyres
where not from the same maker. Before the swap the front had Pirelli
Scorpion Zero with a good 6+mm of tread, the rear Goodyear Wrangler HP
with about 4mm.
