Tyre feathering

Just got a brand new MOT on my chariot, a 2000 Discovery TD5. The tester
noticed a hint of feathering on the inside row of tread blocks of all four
tyres. The tyres are the original fitment 235/70 items with plenty of meat
left (the vehicle has only done 39k) and there's no play in any of the
suspension, steering or bearings. His comment was: "she's just like new".
So what would cause the tyres to feather if all is tight and sweet? I keep
the tyres at 28 front and 32 rear so maybe I'm wrong here and that's causing
it? I'm not going to lose any sleep over it but I'm curious now and would
like to know why all four tyres are showing the same symptoms on two
different axles.

TIA,
Steve

Look back a few days. There was a thread on a similar subject. The
pressures may be 'to the book' but they're too low.

Hmm. I can't seem to find anything.

I've had a quick look (trying to get away on holiady so little time)
and can't see it either.

The subject was not, as far as I can remember, specifically about
feathering but rather tyre pressures in general. The concensus from
memory is that Discos/RRC behave better at some 4psi all round above
book figures.

I run RRCs at 34/38-ish which works well.

Perhaps one of the original contributors could pick this up again. It
looks as though the subject may be hidden below an unconnected thread
title.

Low tyre pressures, especially the front ones. The "book" figure of 28 is
silly. I have no idea why they recommend it, the only time I've found it
makes sense is on a series with cross-ply 7.50s on the front.

Try 'em at 36 all round. That's what I use on a 300 TDi and it's what I
used on the V8, using that size tyres. got exemplary tyre wear, the ride is
a tad harsher but the handling is better (sharper) as well. Discos have a
reputation for edging front tyres, and I reckon that's mostly down to tyre
pressure.

if you carry heavy weight or tow a trailer that transfers noticeable weight,
you may want a bit more in the rear ones, but for average use, 36 works well
for me.

Best bet is google groups, advanced search, group alt.fan.landrover,
keywords "tyre pressure", limit search to the last 6 months and you'll
pick the thread up and be able to read all contributors' opinions.

IME as a garage owner who has sold a fair few tyres and looked after a
fair few LR products, and from covering a load of miles in LR vehicles
of my own you'll need to run 34 or 36 psi all round to get decent
handling and tyre wear.

Many thanks to everyone for their suggestions.

Steve,

I believe that the book pressures are 29 front 38 rear, which is what
I run mine at and they look pretty good. I have to admit they're
getting pretty low all round, but it's quite some time since I
replaced them. The car has done 104K and this will be the 3rd set of
tyres when I replace them.

Do you drive over a large number of speed bumps? I was told that if
you try to straddle the bumps then the wear on the inner edge of each
tyres tread is increased massively. Apparently, the best way over is
(if you can) with one side on the flat road and the other over roughly
the centre of each bump.
