Not just any tyre repair, this is an M&S tyre repair!

Not just M&S tyres..;), we also fixed Town and Country tyres (remember them?), Lorry tyres, Earthmover and Tractor tyres, even wheelbarrow tyres oh and those massive load carrying belts that carry rubble, earth coal etc over massive distances at quarries.

I'm not talking about a minor repair which is what a plug and patch is, compared to a professional tyre repair it is a bodge.

Its quite obvious the OP's damage was beyond the scope of the tyre fitting centre, or the repair would not have failed so quickly.

'''What major repair did it need? Do you even know what you're on about? '''''

You apprently are a qualified mechanic so you repair cars, you are not a qualified or time served tyre repair specialist.

I am, or rather was, so yes i do know what i am talking about.

Its quite obvious the tyre needed to stripped, spread and closely examined, then depending on damage found, the damaged area rasped out to provide a key for new uncured rubber filler, which exposes the cords for closer inspection still, then if still repairable a reinforced patch would be assigned for inside, the inside buffed and the new uncured patch fitted.
The outside carefully filled with uncured rubber.

The tyre will then be cured for so long in the correct sized mould, then the outside buffed to perfection and if it had tread damage the original tread recut into the new rubber.

That is a major repair.

I properly repaired hundreds of tyres bodged with plug and patch kits that failed far sooner than this one has.

Plug and patch are OK for a simple nail hole, BUT the tyre needs to be stripped from the wheel and thoroughly examined inside every time, i sincerely hope those who use these kits do this.

Unless the tyre is stripped off, no one can know exactly what damage has been done, that 1/2" nail removed might have been 4" long when it went in and has been worn down as it worked its way out, gradually ripping the inside of the tyre to shreds with every revolution and flexing of the tyre.

so I guess my cunning plan involving a rubber band and some superglue wouldn't pass muster

More seriously, what is the cost of the sort of repair you are talking about? Is it even worth considering a run of the mill road car tyre?

tl;dr...

Did it take you long to find that on Google?

And that is what they would've done and what I've seen every single tyre fitter who has repaired my car tyres do.

i could have written exactly what gilbert said and like he i wouldnt need to google and paste

we need the original poster to show us the exact place of repair before proper due judgment can be made

So your local tyre fitter has all the various sizes of the necessary moulds and mandrels, rasps, buffing machines, access to uncured rubber and curing solutions, knows how to and makes the various patches required for affixing to the inside of the tyre...about the only thing he will have of the professional equipment is possibly a regroover, but only lorry tyre fitter would know how to use it.

Go visit a tyre repair workshops, its as far removed from a tyre fitting bay as you could imagine.

Now would you like to reply sensibly or will you slip in some more insults or accusations, you don't know everything, none of us do, but this was my game many years ago, i was taught by two chaps who pioneered the modern method of major repair of pneumatic tyres.

I might have a google though now you've suggested it, be surprised if there's much on the subject, another diminishing skill in a throwaway world, mainly commercial, earthmover and agricultural tyres get major repair work these days, due to lack of knowledge and ill informed advice most car owners go to their local tyre fitting bay and in due course might well end up with the OP's experience.

Much the same results are seen with mechanical problems if an owner goes to a fast fit joint and then wonder why what should have been an experts job gets ill diagnosed and subsequently bodged..

Your cunning plan isn't that bad, no worse than blindly squirting some goo in the valve and hoping the inner carcass hasn't been torn to shreds by a nasty foreign object...thats what people with repair kits and toy pumps instead of spare wheels are doing every day.

Too many years ago for me to provide an accurate current answer for price, from memory a major repair was about a third the cost of a mid range tyre, a minor repair which would be a small inside patch without reinforcing bands but vulcanised in place would be about 2/3rds the cost of the major, minor cosmetic damage we would also class as a minor....costs vary according to tyre size.

Is it worth it?

Well much depends on how close you are to someone who can do this work, they are few and far between, some run a fleet of small lorries that collect and deliver nationally, probably best to contact one of the specialists and they would tell you where to take the tyre near you for forwarding to them.
Several in Northamptonshire where the techniques blossomed, one near Ely and i couldn't tell you about any others, must be some kicking about, i have looked on google for tyre repair specialists before, few hits.

Certainly worth getting decent stuff fixed, i've been out too long to say whether runflats for example could be fixed...wouldn't touch 'em with a bargepole so won't be finding out for meself.

4mm of tread? Only about 1000 miles off replacement anyway.

What a load of balls, by your reckoning the tyres will only do just over 3000 miles from new (8mm) tread then?

Either you're Colin McRae or maths isn't your strong point
