When I did this for a living, the technique was to remove the tire,
buff the beads (we used a special buffing wheel in a drill, that
wouldn't remove good paint, but took off loose paint, dirt, and rust,
but a wire wheel will work. Repaint later, if you care.), apply a
seriously gooey and sticky bead sealer on the bead surface, and
remount the tire. If I were doing this to my snowblower, I'd go with
tubes. You may be able to find them with pre-installed sealant in
them. If not, add it.
