The plug is not a piece of metal its ruberry but softer it will contract. So it will not be any bigger than the original hole.

I had a puncture before that needed 2 patches to cover the hole. The patch outlived the life of the tire thread.
I mean originally, only a nail was in the tire. Then they used screwdriver to make the hole bigger so the rubber plug could fit (as many who users who saw the procedure reported).

If the new shop will put patches inside. He still has to remove the rubber plug? I thought it would remain. What happens if it would not be removed? Without any thing to block the rubber outside, won't air/water from outside like flood, can slowly seep into the belt/ply system over the years?
