ABSTRACT:
A method of separating the bead of a tire from a rim to which it is mounted in a tire/rim combination. One step of the method involves providing a tire lifting device having a working end including a rigid bead puller and a flexible positioner. Next, a sidewall of the tire is depressed, such as via a roller, in order to produce a gap between the bead and the rim. The working end of the tire lifting device is then inserted into the gap such that the flexible positioner engages the rim and the bead puller engages the bead. Finally, the tire pulling device is moved such that the bead is pulled over the rim.
