Saw a nail head in a front tyre , so took the car into my local tyre shop . a minute later, and without removing the wheel, job was done , £10 thank you very much.

The guy took out the metal head with a pair of pliers( a sheared stud, as it happened ) which was luckily in the middle , warmed a stick of sorts with a cigarette lighter , and pushed it into the hole, declaring the job done once the pressure was topped up .

I was fully expecting the wheel and tyre to come off , then for the hole to be prepared and patched.

what's this all about, a proper repair or a bodge ?

depends where on the tyre the puncture was, but o certain areas of the tyre a plug is a recognised repair.

it wasnt a puncture though
a foreign object had penetrated the casing and was at risk of getting rust into the carcass so he sealed it with a rubber compound

he probably saved your life 5 months from now when the water that might have penetrated boiled and blew your tyre apart and caused a big big accident and held up GB for a day

round here there are tyre shops resembling downtown Kabul that advertise in broken English painted on curled plywood sheets : ' Punctre £5 ' - SIC - , just don't ask for a receipt or to pay by card

And if you want to know , there are 2 on the West Hendon one way system, which is about half a mile from Staples Corner , junction 1 of the M1

And this is North London , with respect , not some wasteland Oop North, so I don't know who would pay £17 to repair a puncture

what's this all about a proper repair or a bodge ?


If it was a puncture, I'd say a bodge, compared to the fix I had done at National the other day, which was:

Remove wheel. Inflate.

Spray with soapy water out of a trigger operated garden squirt.

Find/mark hole.

Remove tyre completely.

Remove penetrating object (a copper roofing nail).

"Drill" hole out to about 5mm.

Buff inside of tyre clean with abrasive tool around the hole.

Apply adhesive.

Press in "mushroom" patch.

Snip off stem of patch level with tread.

Fit new valve.

Re-fit tyre.

Inflate.

Balance.


The above for £16. I don't think the valve was strictly necessary, but I was pleased with the cost and the repair.


However, if yours wasn't a puncture...

Thank you for that information. It's currently in the boot! Two new Barum 88T tyres fitted at the same time, which seem quite good (although anything replacing worn-out tyres will seem better when they're changed, I guess!).

I guess I wasn't clear initially : the metal stud was sticking right through my tyre, flush with the outside surface roughly halfway across the tyre . When the operative pulled it out ( a sheared steel stud about 4 mm diameter and say 40mm long ) the tyre began to lose air rapidly , so it definitely was a puncture

Should I be concerned with this ' plug ' repair ?

I would be - although years and years ago, it was possible to buy a length of round rubber, a big needle thing, and a pot of glue/goo to repair tyres, I don't think it was regarded as a permenant fix even then... but ICBW.

tyre repair - was I done ? - ForumNeedsModerating
I would be concerned about the repair - not necessarily thinking about catastrophic future 'blow-out' scenarios at high-speed (although these things are alwys possible I suppose), but for the fact that the puncture 'plug' was applied from the outside.

I assumed the idea was puncture plugs were conical in shape (with the 'point' facing out or roadwards) so that tyre pressure couldn't push through the plug through if the glue failed or weakened.

The drill I got was similar to FT above: tyre off, make hole cone shaped (from inside to out), fit cone shaped plug with glue, inflate, leave a short & re-fit. Then check again frequently that plug doesn't protrude or pressure lessen.

This was done free, incidentally, by my 'regular' local tyre-brake-exhaust-general-mechanic
type country garage whom I frequent for non-service items - I still buckle to the 'full manufacturers service record' for standard service book entries though.

The plugs that National used were like enormous tin tacks, or drawing pins. These look just like them:

www.tyre-rite.co.uk/searchresulttyreRepair.aspx?Ca...7

The white bits are removable backings that keep the patch clean until used - just like similar stuff on bicycle tube patches. The spine is, I think, just used to locate the patch accurately, the seal being the round "head".

As I see it with an internal 'mushroom' repair the head reinforces around the fresh hole and has about 35PSI pressing it into position. A repair from the outside is not going to reinforce the hole and has about 35PSI trying to push it out.

Another thought - I'm sure when I had a mushroom plug fitted at National, it was a vulcanising patch as well - a hot air gun was used for a short while.
tyre repair - was I done ? - barneybear
I suffered the same fate yesterday. "Just Tyres" in Luton did a great job (see an earlier post for thoroughness. the "patch" was indeed conical shaped, applied from inside, pulled through and "stuck". The guy doing it really knew what he was doing and was very careful not to get the thing stuck to himself. They display all the right info about what can and cannot be fixed. Other posts suggest "curing" but that is only for "major" repairs normally on HGV etc where the tyre is placed in an oven. My tyre was perfectly road legal as soon as I paid £16:69 (how they arrive at that I have no idea). All other local folk such as Kwick fit/ATS were in the region of £17-£20. Etyres do a free repair service if you have bought from them before, otherwise £20 too. I'm happy with a good job at good price and friendly banter too.

Sorry MP, been away.

IMO this repair is not of sufficient quality to seal and strengthen the possible damage caused by type of object you describe as penetrating.

The object may well have broken a wire or two as it embedded itself, and then have been happily waggling itself around doing a bit more before the air leaked out.

IMO, the tyre needs to be removed and an experienced tyre repair specialist should spread the tread and examine, also it needs to be looked at from inside the casing.
Your tyre may well need a professional repair involving buffing the inside, fixing a proper reinfoced repair patch (not a glorified cycle tyre repair kit), outside damage scoured off, filled with new uncured rubber, then vulcanised and regrooved and buffed to finish.

I have seen so many cases where the nail/screw/implement/whatever penetrated at an angle and as the tyre flexed the embedded weapon was tearing the inner wall from the sidewall and or ripping the inner lining around the penetration.

And my last sentence is the main reason i will never use a tub of goo and a toy inflator should i have a puncture.
A flat tyre needs to be removed and inspected by a competent person.
Tyre fitters are not usually tyre repair specialists.

I shall start a thread about runflats soon by the way (sorry all) but i saw a rather disturbing scenario involving one of those.

oh my for a bunch of car blokes some of you are idiots !
all tyres repairs should only be done by a skilled tyre repair specialist with all the correct and legal repair materials , a string repair is used only to get you out of trouble and is never a repair to be used for more than a few miles or in the case of no spare or in a unsafe area to change a tyre ,

all tyres which suffer a loss of air must be stripped and checked for internal damage to the sidewall .

I remember when tubeless tyres first came in, and yes, we did think that stuffing a bit of rubber worm into the hole was good enough. I think you could even buy a kit for doing it yourself. But times move on, and I can now see that expecting something like that to be safe for anything other than a cautious get you home is madness. You might as well just leave the nail in to plug the hole.

This is a matter for long................... debate in the industry , the old thnking was on the front but many tyre manufactures now state on the rear as most cars are front wheel drive with power steering and abs etc etc thus giving you more comtrol to the front of the vehicle thus best tyres should be on the rear . but beware some vehicles have diffent front and rear size tyres ,

we advise fit to rear, when possible but if customers want them on the front then thats what we do , customer is always right !

Surely, the opposite? If the front tyres are doing more work (providing drive in addition to the rest..) & clearing the majority of any water when wet, I'd prefer (if a choice was unavoidable..) to have the best in front. Fwd tends to understeer naturally, putting the 'worst' tyres there will surely exacerbate & enhance that - a bit of understeer from the back (with the more worn tyres) of a FWD may even help counteract that, making the cornering more neutral.

As you'll have gathered from some other replies, this topic crops up in a regular and tedious way on this forum. Considering how long you've been posting, I'm amazed you haven't been involved in one of the exchanges before. Hence, I thought you were trolling, like some other esteemed contributors clearly are doing!

I've reached the point where I can't be bothered typing out the replies to this anymore. My views on the subject can be found via the forum search if you think they're worth reading. My views all fall under the general logic of rear axle stability being *much* more important than front axle stability for cars for both tyres and brakes - despite this sounding wrong, it's true!

Generally, tyre manufacturers and vehicle manufacturers recomend keeping the best rubber on the rear axle. There are exceptions, but, generally, this advice is correct.

No need to give me the benefit of the doubt. I don't go all the way with the received view either. Tyre tread only improves grip in wet conditions. In dry conditions the less tread the better.

If my rear tyres were on the verge of illegality I might in some cars put the new ones at the back instead. Generally I wouldn't though, for the simple reason that you only really need maximum tread, sipes and so on for emergency stopping in a straight line the wet, and most of that work is done by the front wheels.

I don't presume to advise anyone else. But that's what I think where my own car is concerned. I'm not alarmed by the thought of a bit of tail-happiness.

Such debate, controversy & divided opinion about 'newer tyres front or back' tells me the matter isn't as straightforward or clear-cut as the zealots might think.

In fact it's interesting, that mosted heated discussions only come on topics where there is no unanimous answer - in that sense NC's allusion to 'flat earther's' was singularly inappropriate. The Flat Earth Society is no more! The Sphere-ists have clearly won!

There's nowt more frustrating for a scientist or engineer than having a paucity of facts - it's enough to make them go all irrational & become more like blind acolytes to their cause than reasonable weighers of evidence.

I'd wager the real answer is that it doesn't make much difference either way. Given the many different conditions & circumstances a vehicle & driver might find themselves in, I'm sure there are times when better tyres on the front would have mitigated the situation - vice versa too of course!

I have, incidentally, read many posts/threads on this on the site on the subject & seen the 'learned' answers of some - but remain unconvinced there is a unversally correct answer to cover all situations & contigencies.

I still don't see that repairing my own tyres from the outside is a problem. The repairs are as sound as a pound, as the string gathers up on the inside to form a knot soaked in the putty and adhesive. Even if it does fail it would be no more likely or worse than just running over another nail. Obviously I am talking about small prick punctures than close up, not gashes big holes. Anyone who watches the Police programmes with cars which have had a stinger deployed on them will know that a modern car with independent suspension will take running on flats and even bare rims in it's stride. e.g.

Taking a tyre of for a repair is a good opportunity to inspect the inside of the tyre.
Im assuming Hamsafar your way of repairing the tyre is if you come out on a morning and the tyre has gone down overnight? ,however ,if you mean you were driving and the tyre went down then there is quite possibly internal damage caused by heat build up and the rim attacking the sidewall

frankly i think your logic is flawed and dangerous
tyre repair - was I done ? - gordonbennet
I still don't see that repairing my own tyres from the outside is a problem.


The trouble Hams, and my first years at work (before and after leaving school) was with a tyre repair specialist, is that until you examine a tyre properly from the inside you have no idea just what the damage really is....car tyres included.

That short tack you pull out may well have been 2+" long before, but tapping on the road wore it down steadily as it worked itself out, it may well have been striking the sidewall repeatedly as the tyre flexed cutting the nylon sidewall bands gently with each stroke....a blowout in the making at high speed, not something i'd court.

Having suffered a very rapid deflation of a truck n/s steering tyre approx 2 years ago, probably 20 seconds to fully flat, it was surprising just how difficult it was to keep the vehicle in a straight line even with good power steering, truck empty and in good road conditions, IMO it's the rapid/instant deflation thats the dangerous one.

Purely out of interest vulcanised major tyre repairs completed by the small company i worked for were approved for remoulding by most retreading companies as indeed were Michelins own major repairs...many other repairs spotted at casing inspection time would usually render them scrap.

Edit...BB beat me to it again.

paucity of facts


There is no paucity of facts.

That rear axle stability is viewed by engineers and legislators as most important for vehicle stability really is a closed argument. It's only in bar room type discussions with lay contributors where there is any "controversy".

That rear axle stability is the more important is evidenced by these consistent facts;

- in the fundamental sense modern cars all are set up to understeer with a large margin - they need provocation via the pedals to make them oversteer.

- rear locking of brakes, and hence the loss of lateral grip has been legislated against for many years before the universal fitment of ABS became law in about 2004

- tyre companies and most car manufacturers recomend fitting new tyres to the back axle


Now, if tyre companies were saying that you must renew all 4 at once, you could argue that they were saying this to sell more tyres, but, simply recommending new tyres to the rear doesn't make the tyre companies or the car manufacturers a penny.

There really is no debate and no controversy. Flat Earth was spectacularly apt.

It's only in bar room type discussions with lay contributors where there is any "controversy". >>


Exactly. [ ;-) bar room = backroom :-) ]

Oh dear.
My annual visit to France always brings a trip to the local tip.
Every year I find a nail or screw in the tread (either by daily inspection or by listening to the rotational click of what is usually gravel in the tyres).

It happened again today.
Tip trip + 1/2" screw.

So off to the local garage where he unscrews the offending item, sticks the small screwdriver in the tyre to prevent air loss, brings out a length of red plug (meche over here) waves a magic wand & reinflates tyre.
A few euros for beer money and goodbye till next year.

I don't think I was done - and this is the 3rd year in a row going to the same local garage in the middle of nowhere.

I count myself fortunate he didn't get out the welding gear, as he also repairs tractors, combines....

Are you an acoustician?, structural dynamicist?

Neither of these. But I do work with numbers, often in an automotive context.
Not very Helpful, but there you go ;-)

good guess, bb....but not even close.
best stop the what's my line before the mods cut in.

On topic: the tyre involved was a Michelin with 3-4mm tread.
I am just off to inspect said tyre and repair with a ?3,89 bottle of Chinon from Super U.
Apologies if I'm not back till tomorrow.

Sorry, it was unseemly of me to pry.

I ask because it's an area of design and engineering which I find rather fascinating, but once you look at it in any serious way, extremely difficult and complex - especially at higher frequencies / modal densities where a statistical analysis is effectively forced upon you.

As I worked in acoustics for many years, (machinery health monitoring, narrowband analysis). I am a self confessed "noise freak". I would notice a nail or stone in a tyre, (at low speed), or any change in the many noises produced by my car. As far as I am concerned a noise indicates a change of load, friction, or another problem like a noise insulating mounting or bearing breakdown. I believe in catch and fix it early and save money.

i must be a noise acoustician then
having run rubbish cars and listening for the slightest varriation in toothed cam whatsits since i got my driving slate slab its been a pleasure these last 15 years to have cars with low maintainance and a plug chop unnecessary at the side of the road

Its not black magic, smoke, or mirrors, (unless you are a service receptionist), anyone can tell if their car is more noisy than usual. All a case of degrees of sensitivity. You may remember I said in another thread that my car was quieter after an oil change.

ON,

You might not like a convertible.

Different noises with the top up or down.

I found it distracting in the first month or two I had the CC3.

I dont even like sunroofs, any fold up roof in this country is just a fashion statement.

Ultimate fashion statement = convertable 4x4 (with low profile tyres, on thread bit).

Disagree on that.

Bowling around in the CC3 with the roof down is much more fun than doing the same journeys in my previous Focus.

Not always, surely? Not if he is demanding something that is illegal, or is being abusive to your staff, or is demanding an unreasonable refund?
