I just picked up a plasterboard nail (Sheetrock/Gypsum board) in a nearly new front tyre  Mushroom patches as a puncture repair -What is the collective wisdom 178468 

The guys in the local bike shop said they could do a mushroom patch on the inside akin to this one..

What is the collective wisdom on the safety of these or should I bite the bullet and order a new tyre for our impending Excellent adventure?

I picked up a self-tapping screw in the front tyre within nine miles of the tyre fitting (Harrys tyres in Belfast).  Sad 

Luckly I spotted it when filling for petrol, so pumpted the tyre back up and rode back to them. They fitted a mushroom patch, which stayed in the tyre until replaced after a normal lifespan.

So my vote, as long as they nail is in, or close to the centre, then you're good.  If closer to the sidewall then not so good.

I had one in the LT front tyre for over 12 months and put a lot of miles on it. Used a proper mushroom patch and its quite safe, would be worried about the trip either. I travel with a repair kit but they are not mushroom patches, just a get you home job. However they don't 'blow out' the way a tube does so you get some warning its going.

Shouldn't be a problem just need to check the balance again to be sure.

"Man sacrifices his health in order to make money.
Then he sacrifices money to recuperate his health.
And then he is so anxious about the future that he does not enjoy the present; the result being that he does not live in the present or the future; he lives as if he is never going to die, and then dies having never really lived."   Dalai Lama

I've used a Stop N Go 'mushroom' plug on a brand new Z6 Metzeler and instead of replacing the tyre once I was near a workshop I wore the bloody thing out. It never leaked air. I checked it at every ride. When I took the tyre off the wheel I couldn't find any sign of the plug on the exterior of the tyre until I looked inside the carcass. It was that melded in to the rubber.

Your shown 'plug' is a different animal, and possibly a more 'permanent' solution, but I'd trust them.
