I understand how the screws work but if I dismount my tire so I am able to clean out all of the shavings how will the tire remount. When you shoot it full of air to pop it onto the rim seat or bead wouldn't all the air shoot out the screw holes? Or do you suggest either or starter fluid maybe. Might be stupid question but could use the help before I drill the rims. Thanks for any help you at PBB are great help
