Abstract
A portable tire bead breaker utilizes a common jacking apparatus to lever a curved foot member against the bead portion of a tire/rim combination. A top stabilizer keeps the curved foot member in the proper orientation and a bead engaging foot member permits the breaking of difficult to break bead on tires having soft and limber sidewalls.
