Workmaster, I'm having trouble picturing your bead breaking procedure. Man, a video would be great! lol ... Seriously, you lost me at ... okay, the post is laid down, then drive up on the post like going up a ramp??? then what? You never know, this info might come in handy some day.
The big Railroad Maintenance trucks that came into the tire shop I worked at had split rims. Don't remember the size - not as big as a tractor tire for sure. Think they'd of been close to the size of a semi-truck tire, maybe a tad bigger. Anyhow, after the air was let out, we'd bust the bead with a 10 # sledge hammer. Some broke easy, others took quite a beating.
Oh, and my disclaimer: I've since learned that split rim tires can be dangerous, so please don't try that at home.
