I seat the bead up on tire after install. Then deflate and pry down a spot. Being the tire has been seated, usually it is no problemO to get it to seat up. I actually have been using knock off beads off e-bay from a place out in AZ. If you really want to do it up, mount the tire get your beads in and deflate agin. Carry it on down to your local auto dealer service dept and they probably have nitrogen you can get the tire serviced up there. The dryer the air the better, limits the amount the pressure will vary upon heating and cooling.
