The Atlas Automotive Platinum Center Post Tire Changer, No. PTC500, can service vehicle tires with a diameter of 44" or larger. Its bead blaster system and featured center post help improve safety and reduce opportunity to damage the structure of the wheel, the company says. The easily maneuverable dual assist arms help make mounting and dismounting each wheel a simple and easy process. The patented Lever/No Lever system allows users to switch between the leverless feature or the traditional manual tire bars and does not require any manual tools to make the transition. The tire changer is equipped with a 110V motor and a patented smart and quick locking system designed to immediately lock the wheel in position without having to thread the center cone manually.
