I've searched high and low (not to mention far and wide) for a
definitive answer to this one. Land Rover suggest 28 psi front and 48
psi rear. The vehicle usually has 3/4 bodies in (still kicking) but
otherwise unladen. I'm running Pirelli scorpions if this matters.

Cheers all :)

From experience I'd probably run about 34 or 36 on all 4 corners.

if they're normal size, i.e. 235/85R16 or similar, I'd reckon 36 psi. If
you have fat ones such as 31x10.5R15 then you might go down to 34.

 
I had the same problem and run 28/35 lite load on 235's for years with good
performence and wear results but am still not convinced that this is correct
!!

48 psi sounds very high, 38 psi seems more like. I'd check, but that
could be a transcription error.

Thanks all - it seems I'm no nearer a definitive answer. I think I'll
start with the lowest suggestion and work up until it 'feels' right!

Surely LR's specified pressures are a defintive answer?

LR's "definitive" pressures pre-date radial tyres!

Not on 110's - indeed LR derpicate using crossply's on coil sprung
vehicles.

and fer ages they didn't alter the sods, either, depsite everybody and
sundry using radial tyres. I had some Xplies on the 110 initally and they
were crap, vague steering, hard ride, just generally horrible.

 
Reminds me of my kids comments on my wifes driving. I have been in hospital
for two weeks recently and wife drove 110 to and from instead of Ford
Fester.
Boys turned up for a visit after dropping one son of at minature railway (
along country roads ), " how did it go ? " " well mum met another car on the
narrow road " " so ? " " well when we got back on the seats she reminded us
to put on our seat belts !! "

From the handbook--
Unladen 25 front 30 rear.
Laden 30 and 45.
The tyres are your first shock absorbers,if the are hard more shock will get
through.
If the tyres are softer, they will transfer less shock.
I run 25 and 30.

Whilst this may be LR's official guide, IMHO it's all bollocks. Rear
pressure *must* change with load, and you can't tell me that the rear of
an unladen 110 weighs more than the front, but that's what these
pressures say. Also radials need *more* pressure than the equivalent
cross ply, so the 600x16 to 205R16 pressure change is completely backwards.

I've been a mechanic for the last couple of decades and have fitted and
sold a reasonable number of tyres during that time. I've also owned a
fair few Landrovers of various models and put a fair bit of effort and
time into working out the optimal tyre pressures both for handling and
tyre life. 47 psi in crossplies on the rear of anything but a heavily
laden LWB Landrover is going to be lethal especially in the wet.

My suggestions as a starting point for 110/LWB:

600x16 30 30
750x16 28 28
205R16 36 34
750R16 34 34
235/85R16 36 36

And if laden add up to 10psi to the rear and 4psi to the front. For a
90/SWB drop the rear 2psi or so - my father's SWB on 750x16 tyres showed
wear patterns suggesting overinflation when running lightly laden with
28psi front & rear.

Of course in the UK you have some spastic law about obeying the tyre
placard which is (for cars) often actually a bit low because NVH and
ride quality were the foremost considerations in designating the pressures.

Now for my disclaimer - the above pressure guidelines have been arrived
at from my experience with both my own and customers' vehicles and I
think they are pretty much right. If you want to try them do so at your
own risk - I doubt that they will cause you any damage *but* don't blame
me if you're not happy.

true. depends mostly on the roads, I guess. on mostly-tarmac, I tend to
run 36 all round on the disco (235/70R16 Pirellis); however, I've just
acquired an additional approx 12 miles per day on the route on what our
american cousins would call a "gravel highway" - on which it would doubtless
ride much more comfortably at about 28 all round, say, but experience
teaches that this makes the handling "soft" on tarmac, and moreover would
give bad tyre wear. It'd also be too soft for high-speed use, something
which you have to consider for V8 discos and RRs, but this doesn't apply,
for example, to NA diesel 110s.

 
Hmm, oddly enough the tyre pressures on my old '83 Rangie were 28 front, 38
rear - with radials.

The tyre pressures specified for my '86 Rangie with radial tyres were 28/38
psi

The tyre pressures for my current '95 RR (p38A) are 28/38 - on radials.

Does that tell you something?

The tyres pressures specified work well for me and give good tyre life
(80,000-100,000km).

Maybe LR knew what they were talking about?

Oh, all tyres were/are Michelin - 205R16 on the older cars and 255/65R16 on
the P38A.

65mph flat out, wind assisted and on a downward slope.

I doubt that's enough to worry unduly about higher pressures in tyres for
extended high-speed running. our 300 TDi, since I breathed on the engine a
bit, will indicate 100.
