They are very small (maybe 1/16" or so), perfectly round, smooth, ceramic beads. They look like little pearls in the bag. By themselves, I doubt they would do any damage to the inside of a tire, especially since the ten ounces they add to the tire is comprised of what looks like several hundred beads.
When they add the beads to the tire, they just throw in a pre-measured bag. The bag keeps all the beads inside the tire during the mounting process, but is designed to break apart during the first few rotations of the tire. The beads will then disperse to balance the wheel. Pretty cool, actually.
I recorded the entire tire change on my iPhone and once I have edited the footage I'll post it here.
