understanding we're in dire straits here - the problem of getting the tire off the rim is an issue.

well, garland, i agree with you that the tire iron or jack handle is the way to go. a few drops of motor oil - using the dipstick - on the bead might help to slip the bead past the rim.

if that doesn't work, next step would be to break the bead.

using my leatherman wave's blade i would cut my way down to the bead.

the leatherman tool's file has a 'file' surface on three sides. i would attempt to file through the bead - perhaps using a bit more of the motor oil to ease the way.

if that doesn't work - how many would actually practice this? - i would try to pry each strand of the steel cable bead apart and cut each one with the wire cutters.

if that didn't work i'd sit down and cry - just before starting a large wood fire ! lol !
