Repairing runflat tyres yes or no ?

[pills]

New winter tyres on Sunday, Michelin Pilot Alpin runflat BMW *. Nail in centre of tread. Local tyres place stated will not repair however the Michelin website states they can be repaired, any thoughts or expereince please. I do trust the local tyre place and I am willing to take expert advice if they think a repair might be unsafe but I'm confused as Michelin state can be repaired.

It depends on any damage to side wall if you drove them while flat.
I’ve had the Z4 repaired in the past no problem. Just as long as you never used the repair goo.

Thanks shambolic, fitted them Sunday and was out Sunday night (further complication the car is blue light fitted and approved for responding) - did 2 jobs with it Sunday night - not low pressure warning - started it yesterday and TPMS came on, so no idea if any damage done but I would have thought it would have flashed up a warning sooner?
I think on reflection due to the use of the car I'll just get a new tyre, don't want to risk it letting go on a blue light run.

We repair them but no more than 2 repairs in the same tyre, the only proviso we give is that you should not treat them as runflats anymore.

When it comes off the rim you check the inside for damage and if it has been run flat you should see any damage on the inside of the tyre wall (towards the tread).

Thanks for the advice !

Aye, it'll be pretty obvious and you may also see some 'marbles' as I call them. I've had several run flats repaired over the years but not everyone will fix them and I've had a whole range of stupid excuses as to why not including, 'they can't be repaired' and 'not worth the risk.'

I’ve had a couple of runflat punctures in my own car repaired without any issues ( X3, 3 series )

Work policy for emergency response vehicles was no repair normal/runflats .. always replaced

Yep I thinking it's used for response so new tyre time.

They can be repaired if the puncture isn't in or near the side wall and the tyre hasn't been run flat.

I got a puncture in my 1 Series on Pirelli run-flats when it was snowing less than 5 miles from home. I checked the tyre pressure when I got home and it was still more than 1.5 Bar so I pumped it back up. Next day I pumped it up again to well over the 2.2 Bar regular pressure and took it 8 miles or so to my regular tyre place and they repaired it for £10. I got another 12K miles out of it!

But most of the usual suspects just want to sell you a tyre.

You can understand why some places won't repair them - they have no idea how flat they got & how far or fast you drove on it.

If you didn't see a TPMS warning till you got back in the car as you describe & as long as the thing is a neat hole through a block in the middle of the tread then I'd be happy to get it repaired and use it (and have done with an almost brand new tyre before now). It only takes a 2-3lb drop to trigger the TPMS on my 1 series.

If you did any distance on it at any speed with it flat then its not worth your neck for 100 quid I'd say!

Michelin usually insist on a mushroom plug repair done from the inside AFAIK. The one I had repaired was done from the outside & lasted for the life of the tyre.

It shouldn’t really matter how many miles you’ve driven on it as long as it’s not damaged. Any damage is really obvious once the tyre is off.

I’ve had this with a local tyre place, I wanted a repair and they said they could do it as long as it wasn’t damaged but wouldn’t know until the tyre was off. I was quite sure it would be fine but when they got the tyre off it was pretty obvious it was buggered.
