I've got an old C10 rim and "bald"tire mounted, in my garage, that I used for a "practice" tire, so people could be shown correct procedure for "plugging" with the rubber coated "rope worm" plugs, and also whatever "plugger" they carried..
all of the "punctures" I created in that tire, were made with a cordless drill, and a 1/8" bit, so they were actually "holes" not "nail/screw Punctures"... I went thru 2 dozen "rope/plugs", a half can of "monkey grip tire cement", and also had a half dozen other "plugs" like the pre-glued mini ropes/with tips, and the "stop-n-go" mushroom ones installed.. the only ones that "leaked" were those latter 2 styles, and when replaced (easily pulled right out) with gummy ropes and goobered with glue, they are still holding air... and that demo was in 2007....
granted, I never "ran that tire", but I'm sure when I do pull it off the rim, I won't be able to force ably pull any of those out from inside the carcass... which I attempt on every plugged tire I have ever had, when I end up wearing it out...never could pull one out.
