Nope!

It works the other way. Any accident resulting from negligence that ends up in court (be it a dodgy tyre repair, tinkering with gas or shoddy building works) requires the person who did the works to prove their competence, assuming it is established who did the works.

Nope, sorry, incompetance has to be proven otherwise there is no case to answer

Unless an "incident" can be shown to have resulted from incompetance in the 1st instance, and not accident, it is not automatically the fault of any unauthorised person that has an involvement.

Update, (not dead yet) see Post #46

I have been looking through my old posts trying to find a particular post of mine, not this one, but I thought I'd reply to this one.

Isn't it funny how my predictions -in the OP- of what would be said in the replies to this thread have come true, although no-one has said "you could poke your eye out with those sharp tools" :rotfl:

Anyway.... The 2 tyres in question which were repaired wore down to legal limit and never lost any air, they are now retired from service.

Recently, I repaired -in the same way- an almost new tyre which had a 1 inch screw in the centre of the tread, it has about 8mm of tread so it will be about 2 years before I report back on how this one gets on. So far so good, no leak, no deflation, rock solid after 2 months.

If you don't see me post a final update at the end of the tyres life on this forum you can assume I'm dead

Yeah!

Good result then.

I guess you are officially competent as well now.

You seem to be very unlucky in terms of punctures fella, I don't thing I've had one for over 10 years. And before you say touch wood I'm not including what happened last weekend. (Only replying here as I back tracked to post#46 and saw something about fetching a tyre off the rim).

Backing out of my drive as I do everyday I bumped down the kerb very slowly, I run out of "drop" if I keep the car on my side of the road. But I must have held it exactly on the kerb as I paused to allow another car to pass.
Drove off down the road for 100 yds before turning right. Car felt abit dead but I put that down to the freezing cold.
Turned right, went over a normal sized pothole and bang, tyre completely off the rim.

When I got back home the rim was deformed in 2 places consistant with the pot holes, but I have a spare identical set, the tyre was put on 1 of these and was perfect, so can only asume was deflated by stoping on the kerb edge.

Just a warning to others that's all.:money:

The doom-n-gloomers will no doubt reply to this thread saying all sorts like:

These are temporary repairs only
Puncture repairs aren't that expensive
What if your tyre explodes on the motorway
Your tyres are the only contact 'tween you and the road, I don't want mine DIY repaired
You could poke your eye out with those sharp tools
You could cut your hand off
You could slit your wrists with the knife.
Don't do it or the world will end.

But if you consider yourself to be mildly capable in the DIY world and you don't like wasting money, and you can decide for yourself whether something will be safe or not...... then read on
However, I do say that you must not repair on the sidewall or on the tread close to the sidewall

I don't like wasting money -that's why I'm here on MSE- so when I get a puncture on my tyre, I'm annoyed, and I know it needs repaired, as it's got 4 - 5mm tread left, getting a price for a repair can be £15 per tyre, but even if it were £8 I'd still think that was a lot, and ask myself could I do better?

So in my searching for a puncture solution I found these thing on Ebay called
tyre puncture repair strings
tyre puncture repair strips

They are sold on ebay with two hand held tools that aid fitting or you can buy just the strings only.

The tools inclusive pack looks something like this


You can see videos on youtube like this one

I also researched the topic on various forums, and people have said they got these sets in poundshops in Glasgow/Ayr, I checked the poundshops in South Wales and they didn't sell them. The forums also said the product worked well and lasted the life of the tyre.

So being a MSE I decided I wanted to try it without the cost of buying the two tools, so I bought 5 strings from ebay, £2 delivered, used the rubber solution in a bicycle repair kit 87p from Wilkinsons. Ideally you will want to buy just the glue in a 15g tube no point buying huge tubes as this stuff -vulcaninsing rubber solution- evaporates over a year from tubes once they are opened.

I decided to push the string into the hole using a screw driver with a 'V' cut in the screwdriver blade, and to ream the hole I used that same screwdriver, I had already grinded the blade so that it was the same diameter as the shaft of the screwdriver this had the effect of creating sharp edges all around the blade-shaft which was ideal to ream the hole out.

When it came to pushing the plug in, it is hard work with a screwdriver, you can see in the video it is hard work with the right tools! I also found that the shaft of the screwdriver being the same as the diameter of the reamed hole - when then trying to get the string into the hole it obviously makes things very tight and the screwdriver blade did cut through the string, after it was in the hole, thankfully. So I pulled out the screwdriver and poked a bit more of the string into the hole. Seemed to work ok. cut the excess off with a stanley blade.

I decided that I would have to make a better tool for pushing in the strings, the screwdriver works well as a reamer although the 5mm diameter might be better increased to a 6mm diameter and use a tool with a thinner shaft for threading the string. I haven't got round to making one yet, but you can either do what I did or just buy the kit with the tools included. I recommend you buy the kits with the tools! but don't poke your eye out

Anyway, I did two tyres the other week and fitted them on the car, done about 500 - 750 miles since and there has been no problem, I checked them today to see what they look like now, I honestly couldn't find the plugs, I had to check three times before I found them, they have both worn flat with the surface of the tyre and turned black, probably with the dirt and dust on the road - exactly the same colour as the rest of the tyre rubber & no loss of pressure.

Two tyres repaired 40p each tyre. :T

Let the games begin!

If you are still driving with these in your tyres then hopefully with the wind behind you, the temporary repair you have done will last until the tyre wears out.

On the other hand what will probably happen is that the repair won't last and you will end up having an accident more than likely at motorway or dual carriageway speeds.

When a tyre is cold and still there is no flex, when a tyre is running and hot there is lots of flex and tremendous force, tyres have to be repaired to specific standards, which is why when a tyre place repairs a tyre, they remove the tyre from the rim and check the inside as well before making a judgement.

When a tyre has been run flat normally most damage can only be visible from inside the tyre, in my experience (Tyre industry 20 years) if you do this you are not putting the safety of yourself or anyone else first, you are merely trying to save a few quid, I've seen what happens to cars that have had shoddy repairs on tyres.:money:

RichardD1970

Have to say I agree with Dors01.

Your (OP) comment about it "only being 30psi" is ridiculous.

It may be 30psi sitting cold at the side of the road, but running hot at 70-80mph there will be a hell of a lot more pressure than that.

Then you have to factor in all the bumps, flexing and other stresses that the tyre has to cope with in normal conditions.

And as previously stated, you don't know what, if any damage has been caused internally or to the structure of the tyre.

Lots of things are done in other countries, doesn't make it safe or advisable here.

Just take some spares with you
