back in his car, when we discovered a rear tyre was nearly flat. I
pumped it up with me trusty Halfords inflator, but I could hear air
hissing out - we both did - and there was a draught coming out of the
tread at one point. However it was dark so I left his car there, ran him
home in mine, and this morning went out to see how flat the tyre was.

Well it wasn't. Flat. The hiss wasn't there, there was no sign of a
hole..in the location where the air had been coming out (edge of the
tread)...

WTF is going on? Rational explanations only please, no alcohol or

You might get a hole that only leaks above a certain pressure - so it
would be worth checking the tyre pressure now and see if it matches what
you put in it last night.

Perhaps some of that rubber-solution-like material
intended to mend small punctures
had been inserted in the tyre at some point?

I once did that with a Citroen Berlingo. I had a massive hangover and I got
in the wrong van and set off to drive to the wholesalers for parts.

Nope. Got the same dents and ****.

When I started pumping it up it was WAY flatter than it is now, and its
been in my drive since then.

Must go and check all the tyre pressures

And the hole where we could feel the air ****ing out was nowhere near
the rim, it was the edge of the flat part of the tread

That probably does away with the theory that it's a different car.

If there's a screw or nail in the tread, it may be sealing the hole. For
now. Temperature would make a difference to the sealing, and the tyre
might have got hot if it was driven whilst nearly flat.

The good news is that some holes in the tread, but not the side wall,
can be repaired for not a great deal. £10-ish. It would be best to
remove the wheel and get the tyre repaired, rather than driving on it
any more and buggering it up properly.

Unfortunately, the "edge of the flat part of the tread" is one of those areas that are not allowed to be repaired.

I hardly ever wear tyres out - they always seem to get punctures and they are invariably near the edge of the tread:-(

I have had slow leaks from one fencing nail, one posidriv screw and several horseshoe nails. Also a cracked BT manhole cover caused instant deflation recently.

You are right. It depends how near the edge, though. See
http://www.blackcircles.com/general/repair

The middle 60-70% of the tread is repairable, it seems.

We have lovely grass sections of the pavements here, that unfortunately
some of my neighbours insist on parking (and ruining). I did think of
scattering the modern equivalent of caltrops on these grass patches,
namely posidriv screws, but that would probably be a mistake.

It is possible that there is a compromise in the tyre and that it only
'opens' during a part of the cycle of the wheel?

Sometimes a tyre will leak in one position but not another, depends
where the hole (if there is one) is and whether the flex of the tyre
changes the shape of it as it rotates.
It may also have become "detached" at the rim and then sealed itself
again with the rotation.
Had many a tyre over the years which would never leak while being used,
but would if left a few days.

Ah, must learn to read the post. I'd also go with the "different car"
theory then

The madness/mistake question should resolve itself as soon as he collects the
car and agres to the state of the tyre..

Assuming that is, that the tyre doesn't decide to deflate again in the
meantime.

In which case all bets are off.

I've had a couple of bike tubes/tubular tyres that were OK when stationary
but went down when rolling. In those cases it was the valve - on one, just
moving the valve caused a hiss - but a car might have other causes.
Also, as ahs been said, the hole might unseal/seal at various pressures.

Are these those tyres which have a substance that hardens when the pressure
drops, ie its a get you home thing, but not to be trusted long term.
BMW seem to fit them on the new minis I understand, which begs the

other vehicles?

2.3 my mate has.

Wouldn't you want to put caltrops in the way of my Mini owner.

Mind you a little red number parked next to me at S/market today and out
popped a dinky little brown number. Kerala I'd say.

Sigh. If I were 30 years younger...
