bunch of w*nkers.
I'd go with 36 front and probably 40 or 42 rear, for road use, depending on
weight carried. Running light, you'd want about 34 all round, I expect.
Note that the book probably tells you 28 for the front. It does that for
the disco. The disco has a reputation for edging front tyres. On mine, the
last set of tyres I ran from new to worn-out on the disco were run at 36
front (235/70R16) and they wore flat and even down to almost minimum legal
tread when I replaced 'em, and they weren't rotated with the rears, either.
The only downside I can see from running higher front pressure is that the
ride is slightly harder. I wish I'd taken pictures of that set of tyres
now... the wear pattern was as near to spot-on as you'd get on front wheels
that steer and drive and brake.

soft sand, you want flotation, so yes, lower pressures and keep the speed
down. Same goes for any soft stuff, really.
