Abstract: A tire removal tool for breaking the bead of the tire from the wheel rim is provided. The tool can include a bead member that is removably attachable to a distal end of a support member that is part of a trailer elevation jack. The elevation jack is rigidly attached to a trailer and has a jacking mechanism for retracting and extending the distal end of the support member. The bead member is dimensioned to fit adjacent to a rim and onto a tire bead, with the extension of the distal end of the support member resulting in pressure being applied down onto the tire bead. In this manner, the tire bead is separated from the wheel rim. The bead member can include a collar with an inlet end and a flange that is attached to the collar at a distance spaced apart from the inlet end. The inlet end is dimensioned to accept at least part of the distal end of the support member. In some instances, the collar has a rectangular shaped cross section, while in other instances the collar has a circular shaped cross section.

Abstract translation: 提供了一种用于从轮缘打破轮胎胎圈的轮胎拆卸工具。 该工具可以包括可拆卸地附接到作为拖车升降千斤顶的一部分的支撑构件的远端的胎圈构件。 升降千斤顶刚性地连接到拖车上，并具有用于缩回和延伸支撑构件的远端的顶起机构。 胎圈构件的尺寸设计成适合于靠近轮辋和轮胎胎圈，其中支撑构件的远端的延伸导致压力向下施加到轮胎胎圈上。 以这种方式，轮胎胎圈与轮缘分离。 胎圈构件可以包括具有入口端和凸缘的套环，凸缘以与入口端间隔开的距离附接到套环。 入口端的尺寸被设计成接受支撑构件的远端的至少一部分。 在一些情况下，套环具有矩形横截面，而在其它情况下，套环具有圆形横截面。
