   > Not generally if a suitable bead lubricant is used.   
      
   Hi Xeno,   
      
   Thanks for your input, as I hadn't really thought about it all that much.   
      
   Thinking about it further, I'm gonna agree with you even though I intimated   
   otherwise prior.   
      
   When I set a bead, I lubricate with dish detergent, and then remove the   
   valve core, and then I screw on a modified airgun so that I can press the   
   trigger to get air in but I don't have to hold it as it screws perfectly   
   onto the Schrader valve.   
      
   When the bead pops for the second or third time, and I check that it's   
   even, I stop pressing the trigger.   
      
   Then I pop the air hose off the modified airgun, and then I quickly twist   
   the modified airgun off the Schrader valve and in that process, the air   
   starts shooting out of the now wide-open valve stem (because there is no   
   core inside).   
      
   I quickly grab the bare core of the Schrader valve and screw it in, using   
   two hands, one holding the valve core (so it doesn't fly away) and the   
   other hand twisting the special core driver tool until the air flow stops   
   and the valve core is seated lightly.   
      
   After that point is the first time I actually _check_ the air pressure,   
   where, almost always, I have to put a bit of air _in_ to get it to the   
   desired 30 to 45 psi.   
      
   Given that's the process, I actually have no real idea _what_ the pressure   
   was at the moment the bead seated itself. :)   
      
   It could be 40 psi; it could be more, it could be less.   
   o It never really mattered to me before, so I didn't even think about it.   
      
   I'm aware that tire burst pressures are likely far higher than my 220VAC   
   20-gallon Sears Craftsman compressor can go to, so I'm not worried all that   
   much about the tire exploding in this process of just seating the bead.
