sentences:  Lastly, the Clamp-and-Ram mechanism tool  is by far the most effective and compact tool for breaking beads on ATV's and other difficult-to-change tires.This style of tool has a pointed foot that enters the space between the tire bead and lip of the rim, and it uses a padded clamp that is driven with a wrench to get pulled in all the way with very little user effort.The Ram foot then gets actuated by another bolt, with little effort by the user, and it completely breaks the bead loose in one motion.
