You should google for "jeep busted tire bead" and see many ways to "fix" a busted bead--
There are 5 methods to repair/recover the tire, if you loose a bead because of low air pressure--
I've used the "BAM" vacuum explosion method with WD40/Thrust/ether, but those can be a little dangerous, so
Now I carry a "pneumatic bead expander", (Ken-Tool) and they make the job a real breese
It's never really "EASY" but can be a light job, especially if you blow BOTH BEADS !!
