Easy way to remove tires from wheels?

[shifty]

You know, I have these four rims I need to refurb, and they have tires on em.

Any suggestions on how to easily remove a tire from a wheel in less than 2-3 minutes?

I tried using two tire irons to break the bead and wedge over the rim like I'd done in the past, but they were cheap tires and came off easy.

The tires are going off to recycle, so I don't care if I gotta cut em off. I gave up after 15 minutes of putzing around and figured I'd come here and ask before proceeding.
