Abstract
A helper arm for use in conjunction with a rim-holding tire changer for assisting with the mounting/demounting of a tire. The helper arm comprises an arm having one end attached to a support device and an opposite end operably attached to an adjustable vertical member. The arm is preferably jointed and pivotally attached to the support device. Controls are provided to enable vertical adjustment of the vertical member. The vertical member may comprise a cylinder assembly having a cylinder shaft that may be moved up or down into operable engagement with the tire and wheel rim. A contact block is attached to the lower end of the cylinder. The contact block includes an attachment head configured to enable attachment of the block to the vertical member. Further, the contact block includes a shoulder having a rim-stop surface, a hook member opposite the shoulder, a heel extending downwardly from the body of the block and an instep along the underside of the block.
