   A proper patch is called a patchplug (as I'm sure you know) which is both   
   that patch and that plug (which you know). It can be a single piece (with a   
   wire do pull it through) or you can do it at home with two pieces.   
      
   Normally it's reamed first but there will always be sharp edges in belt   
   wires (if they're metal layers - and I think all tires have metal layers).   
      
   The thinking, I think, is that a patch without the plug leaves a hole which   
   allows water to rust the steel belts.   
      
   There's also squirming going on, although the plug isn't rigid but it's   
   closer to the density of the tire than a hole would be so we can assume a   
   plugged hole squirms less. Each squirm ever so slightly enlarges the hole.   
      
   As far as I'm aware, the round flat patch is simply to give the biggest   
   surface area for the inside air pressure to not blow out the hole.

   Anyone taught professionally how to patchplug a tire is taught the rules by   
   the rubber manufacturers association (and probably also the tire OEM).   
      
   The main reason for dismounting every damaged tire is to L@@K inside to see   
   if it's damaged (often you'll see piles of rubber "dust" for example).   
      
   The rules say any tire showing damage from the inside (even if the outside   
   has a perfectly pluggable hole) has to be scrapped immediately.   
      
   I've had once where they left me without a tire because they (at first)   
   refused to put the scrapped tire back onto the wheel (I had to beg them).   
      
   Of course, they want to sell you a new tire but they didn't have the same   
   model in stock so I argued that their unmatched tire would be dangerous.
