ABSTRACT:
The improved tire changer tool set of the present invention includes a tire rim engager and a lever. The tire rim engager is in the form of a disc having a depending peripheral portion which may be a detachable ring and which is adapted to securely seat the engager in the rim of a tire. The tire rim engager also includes an upstanding generally central post having an expanded top which retains the lever in position around the post. The tire rim engager can have an annular recess on its bottom surface to receive the top portion of the detachable ring. Such ring can be held in place with screws through the disc and ring. Rims of different diameters can be installed on the disc. The lever is long and generally flat with two portions connected by a step so that when the lever is connected to the post by a side notch in the lever, one portion of the lever is raised and can act as a handle in rotating the lever around the post. One end of the lever has a chamfered or sloped portion which facilitates insertion of that end between the tire and rim to break the seal therebetween. The chamfered end can be removable from the lever end and the opposite end of the lever may include an upraised lip to facilitate forcing a tire during mounting up over the tire rim. The underside of the disc can be cut away to accommodate rims of different configurations. The post can have a vertical opening therethrough to accommodate motorcycle axle ends.
