Hi there, no problem,
Michelin tyres of a "Z" or "W" speed rating are the only manufacturer that allow one 3mm hole punture to be repaired (there is an area limit which is approx the centre 45% of the tyres tread)
No other manufacturer will allow their high speed tyres to be repaired, Michelin have been satisfied by their testing of how they produce their carcass that the consumer can still use the tyres as if it were new,
This is why good tyres supply/fit establishments will refuse to repair other manufacturers tyres with the same problem,
Secondly the dodgy garages will also use car puncture patches which have a 6mm shaft and will ream the hole to double the safe limit that Michelin have tested, it is all to do with how the carcass is made and how many strands of metal or rylon are broken,
Another reason for non repair is which has the foreign body punctured a hole at more than 45° to the tyres.
If a repair was deemed to be the cause of an accident by the rider, police or other party and it was a Michelin, michelin would inspect the repair, if the repair was carried out correctly Michelin would go to court and represent the defending party, As far as I know Michelin have never lost a court proceeding regarding a correct repair, this effectively is support the the rider to obtain compensation from garage or garage to not be held accountable for the wrong reason of accusation,
to make it known, if a repair cause death in the motortrade the company is held accountable and employees in the chain of command down to the fitter face prison upon corporate manslaughter,
Ask yourself a question when faced with a puncture that's the fitter has just pis*ed you of with, are YOU really valuing your life to the cost of one or two tyres,
yes it is not illegal to repair other manufacturers tyres however the manufacturers state do no repairs under there account terms of certain tyres, this means they will not back you or the garage up.

Did not know know this, sure there must be some truth in it

There may of been truth in it once but tyres change so much so quickly that it's likely to be out of date.

I've had punctures repaired in other brands without issue.

i think there is also something to be said about permanent repairs and temporary repairs... also if you are putting the speed rating of your tyre to the test, there might be something about speeding in the court findings too

Fyi, I too have used both temporary repairs (AA etc) and then got fully repaid by tyre fitters after without any issue and then have used the tyres as normal.

I think it's scare tactics to get people to part with there hard earned cash on new tyres rather than repair but if you are in any doubt it will effect your riding so you might as well get a new set.

For me though, a tyre fitter permanent tyre repair is fine and once done I forget about it until the end of tyre life.

Each to their own though...

I think like most things, I agree a good repair will last the life of the tyre, it is when something goes wrong and an Insurance Company inspecting sees a repair and try to blame that to get out of payment, I have actually screwed a wood screw into a tyre with Silicone sealant and left it and it never leaked any air to the day I replaced the worn tyre, (was a car so a little more reassuring)
