   Almost everyone I know who changes their tires at home does it the same way   
   that I do which is you first install a new valve stem and then you   
   immediately unscrew the inner valve out of the stem tube just before you   
   clamp the compressor nozzle on it so that your compressor air is continually   
   feeding into the loose carcass which is doing nothing useful till you seal   
   it off.   
      
   The work is in sealing it off momentarily to give the bead a chance to seat.   
      
   All you do after that is give the air a chance to stay in by lifting up the   
   bead manually by hand or if you have the bazooka you blast it momentarily.   
      
   When it doesn't seat you might need to summon a helper but when it seats you   
   will know in a few seconds. The bead blaster is to eliminate the helper.   
      
   Right now I'm only asking about which size of bead blaster works best.   
   My question can only be answered by those who have done it before.   
      
   Which works best overall?   
   2.5 gallon?   
   5 gallon?   
   10 gallon?   
      
   The tradeoff isn't much in cost but more in the utility and storage issues.
