I've just had a puncture repaired- thankfully no 'drama' - I noticed the
problem before the tyre was 'flat', inflated it, drove a few hundred
yards to a local place, which did the repair. The only 'niggle', it
looks like the offending item was a screw off my garage floor!
I happened to comment to the chap who did the repair something like
'That is the only one I can have on that tyre.' He corrected me and said
that 3 were allowed, subject to positioning. I've not checked the rating
of the tyre (it is on a 4x4) but my understanding was that only one was
permitted. Have the rules changed?
Next question. I know proper type places, like the one I used, remove
the tyre and patch from the inside etc. with a 'mushroom' like patch.
These have a patch on the inside and a stalk that fills the hole.
However, many years ago (in the 1960s) I recall my father having a DIY
kit which you poked a plug, dipped in glue, into the hole from the
outside. My understanding is these were banned - at least that is what I
was told in the 1970s.
BUT I see similar kits are now available and there are numerous videos
of them being used. They seem popular with motorcyclists. I'd have
thought the last think the latter would want is a dodgey repair!
Are these DIY kits legal/any good? Obviously they would only work (in
theory) for 'simple' holes of limited size and in the 'right' location-
on the main part of the tread.
The modern kits seem slightly different from the 1960s one I recall but
the essential principle is the same- a rubber like 'bung' dipped in
glue, inserted from the outside in the hole, after the screw, nail, etc
is removed, and the hole cleaned. The only obvious differences are the
colour- and the modern bungs are longer and seem to be 'doubled over'
When I read tales like this I really wonder if it's just me ... who
has been sent back from the future or that 'most people' are still
very much stuck in the past ...? ;-(
When I hear about people having punctured repaired manually I wonder
if they still also start their cars manually with a starting handle or
have to keep the fuel pressure up using a hand pump as they drive? ;-)
We have several computers in most cars these days ... we have cars
that automatically call for help in the case of an accident ... that
park themselves or stop if something steps in front of them, yet,
'most people' still seem to be living in the stone age when it comes
to dealing with punctures? ;-(
This seems to be especially strange given how many cars don't
automatically come with a spare wheel any more.
Now, I'm not saying everyone should do as I do and treat all their
vehicles with the likes of Punctureseal, but when I think about it I
wonder why they don't?
I guess 'they don't know about it' could be the answer from many ...
or, because of myths or out_of_date information, aren't aware how well
the good stuff works or how easy it is to apply or how cheap it is
given the inconvenience of a puncture etc, especially when spread over
the lifetime of an average tyre.
So it's sorta got to the point now why when anyone asks about or
mentions 'punctures' I'll just shrug ... like someone listening to an
.MP3 player might when someone asks where you can get audio cassettes
Keep banging them rocks together guys. ;-)

p.s. Obviously much of the above is said with tongue-in-cheeks but I'm
still intrigued why I am happy to rely / use the likes of Punctureseal
and many others aren't (or don't, and many do of course)? Don't get me
wrong, I'd hate for someone to also rely on it and it not work for
them but maybe it's one of those things where you would have to
actually experience it in use for yourself ... to have done thousands
of miles on what would have been a 'punctured' tyre with no ill effect
or even the loss of one PSI to 'get' what it's all about?
If the likes of Continental tyres can offer a tyre pre-treated with a
puncture sealing gel, I'm guessing such must be up to muster and given
the RW difficulty of knowing if the tyre you picked up in your own
garage, that got thrown out a few yards later, the puncture sealed
and you weren't aware of any of it suggests that it's ok as a long
term puncture solution?
'Of course' any tyre/ sealant manufacturer would 'recommend' you have
a punctured tyre checked, but how soon do we ever know we have a
puncture (pre TPS) and how many miles might we do with the object
still stuck in there or the tyre slowly deflating?
I know about it, I even have some (or the equivalent that came with the
car) but I don't and wouldn't use it. I don't trust it, the car has a
TPMS with sensors in the wheels, ...... I bought a 'space saver' spare
but, on this occasion, didn't need to use it. The tyre wasn't totally
'flat', I have a decent compressor so could inflate it, and drive the
1/4 mile or so to a local tyre place who repaired it for £15. The car is
new so the tyre has done about 1200 miles- I didn't want to right it off
unless I had to.
When I went to collect the car, there was another 4x4 having a tyre
changed. He'd driven on some tyre and ruined it- it had some kind of
'protection' in it an he'd not noticed he had a puncture. I'm not sure
what it was (the tyre protection) but he wasn't a happy camper. Again,
the tyre had been all but new- although the car wasn't.

<snip> >> I guess 'they don't know about it' could be the answer from many ...
I'm not sure there is such a thing as 'an equivalent, especially if it
'comes with the car' Brian. If it 'comes with the car' that sounds
like a 'get you home' vinyl gunge and *nothing* like Punctureseal.
You have experience of 'it' to not trust it OOI? I wonder what it is
about those who do trust it, how / why they are different? (And we
aren't talking a get-you-home gunge here).
If I tell you I used it respectively to repair two punctures on two of
my own cars and on one car the tyre continued to be fine till I
eventually scrapped the car and the other is on the car we are driving
currently, do you believe me? Do you think maybe that I have some sort
of magic powers that makes the stuff work for me but not for you for
example? I'm just trying to understand ... ;-)
OK, and ... ? The sensors are by the rim and nowhere near the sealant
inside the tread (centripetal force takes care of that, if that was
Good idea. There will always be the time where the tyre get's badly
Yes, you said.
Yeah, you said. *Luckily* you were local to home and not on a busy
motorway, at night, in the rain, with a caravan on the back.
Quite ... and there was no reason 'to' right it off for a small screw
puncture was there? What would have written it off?
Doesn't sound like very good 'protection' as it sounds like it didn't
'protect'? This is exactly the sort of thing I'm talking about. People
(potentially) comparing apples and pears.
So (in an effort to try to find out *why* people may not use the likes
of Puncturseal) you don't trust whatever came with the car so you
don't use something different?
Assuming the stuff in the 'other' 4X4 you mentioned failed, how
different would that be to the tyre without the sealant OOI?
As I said, I really DGAF if others don't use the likes of
Punctureseal, I just wondered *why* they didn't. <shrug>
Thanks for the feedback. ;-)

p.s. Say you bought a second hand car and it came fitted with 4 as new
tyres that happened to be 'Contiseal' type. If you realised what they
were, would you replace them with some 'std' tyres?
If you didn't appear to have a puncture, would you have them checked
If you realised you had a puncture, and it sealed itself, would you
have it further 'repaired' and if not, how would you feel about them
if they didn't exhibit a puncture or any other issues till you finally
wore them out?
Proper geeza. ;-)
Both my Lambretta SX150 and Messerschmitt KR200 had split rims,
meaning I just needed to carry a spare tube (although both also
carried a spare wheel). ;-)
I'd have to say, not having to deal with most punctures on the move is
a real boon, something many take for granted these days with slime
filled cycle tyres etc.
I note that the TPMS system was first brought in because several
people had died because of tires that were being run under inflated,
were than failing catastrophically (tread delaminating / blowout),
causing vehicles to overturn etc.
A second issue is the very slow loss of air because of the porosity of
the rubber itself. This means un-checked tyres can be run for extended
periods at very low (and progressively decreasing) pressures, again,
leading to stress of the carcase and premature failure.
As a matter of course I have always glanced over any vehicle I'm due
to drive or even passenger in, looking for things like damaged lights,
mirrors or tyres that looked 'soft' (or damaged etc).
The trouble is, not everyone does and I have spotted (and warned the
driver if possible) of a particularly soft tyre, when I have spotted
it on the road.
Again, a pre-emptive sealant that helps reduce such porosity
issues has to be a good thing?
Daughter is about to replace the front tyres on her Corsa and I may
take advantage of that to video some 'attacks' on the tyres, as they
are treated with Puncturseal.
I wonder if that would convince anyone as to the abilities of the
likes of PS ... or if they would still prefer to have their (say)
daughter or wife stuck at the side of the road (motorway?) because of
a basic puncture?
As soon as the new tyres go on, the fresh Punctureseal goes in, why
wouldn't you? ;-)
Cheers, T i m
Don't some of the 'run flat' tyres do that? I recall seeing some with
'balloons' of 'gunge' which burst and then expanded. I assume the tyre
was then 'done for' but may be not.
I don't feel the urge to change all the tyres on any of our vehicles to
anything 'exotic'- run flat or otherwise. I tend to buy a 'normal'
quality tyre and deal with the odd puncture if needed. As for 'low
profile' etc., I can't see the attraction. I've never been a 'boy racer'
;-), even in the MX5.
I don't know. I knew one lad years ago who filled a tyre with straw,
but this was on an old A40 we used to drive around some nearby waste
ground. It always looked happy enough, though.
But filling a tyre with some sort of synthetic foam does not seem
completely ridiculous to me. Yet.
I've not seen that. Most 'run flats' are called such because the tyre
stays on the rim and will tolerate being run flat for longer than a
std tyre. They still need to be replaced, including the other non-flat
tyre on the same axle because of the extra stresses it has had to
Better IMHO not to have the tyre go flat in the first place! ;-)
Quite. Nor would I.
I tend to go for a good (primary) branded as a minimum.
You don't have the choice with many cars these days, that's what's
fitted as standard. ;-(
The kitcar has 80 profile tyres. ;-)

Years ago I had one of those, after a some new tyres were fitted. I just
returned to the supplier (I wasn't sure what the problem was), they
found it, 'reseated' the tyre, problem solved. I assume a but of much or
something had got in the way. A bit later, a boy racer drove into the
car and it was written off!
<snip> >I think mine is caused by corroded alloy at the rim - I can see it at
You can do that or clean it up, acid etch prime, paint and seal.
The problem with doing that is having the wheel off long enough to do
a good job.
The ally rims on my Honda CB 250 Nighthawk were slightly porous and so
I tripped them clean, sprayed with acid etch primer, prayed them up
inside and out and left them to cure in the sun for a week or so.
Fitted new tyres and they hardly lose a psi between checks (that is
normally MOT time). ;-)
For a more instant repair they often use a black tyre sealant gunge
that just fills the holes etc.
Cheers, T i m
once the bead seal is broken then conventional old school tyre levers
will remove any normal tyre, bead seal can be broken (often) by lowering
the heavy end of a car onto the wall of the tyre.
But for the average person it is easier to just get a tyre shop to strip
the tyre off, take the wheel home, clean and paint it, then get the tyre
shop to re-fit and balance.
