Abstract
A tire changer which utilizes an elongated bead breaker assembly with a tool that defines a pair of contiguous, substantially planar tire contact surfaces which define therebetween an included angle in the range of about 155 to about 165 degrees. The tool is situated at an included angle of about 55 to 65 degrees with respect to longitudinal axis of the elongated bead breaker assembly.
