Hello together, I have a tiny nail exactly in the middle profile groove of my Michelin 225/55 R16 95V summer ice cream. Since the tire is from 2010 and still has about 7mm profile, I have asked some tyre houses for repair. I no longer look through there. The one plug, fill, glue and vulcanize then for an hour. The others mention a variant with a tip-top stopper system, whereby apparently a plate with stoppers attached inside, but not the spot/re again others only plug from the outside without dismantling the tire. I am not concerned here about costs, but about the best possible safety / quality. Which method should I choose? Thank you in advance for your advice. Michael
