The Atlas Platinum PTC400 tire changer is an Italian-engineered center-post swing-arm machine designed for shops working with modern low-profile, run-flat, and high-performance tires. It builds on the PTC300 platform and adds a center-post layout with improved swing-arm geometry, giving technicians better control and clearance when handling larger alloy wheels. The system supports a 26" external clamping range and up to 43" tire diameter, and runs on standard 110V single-phase power. Note: it requires an external air supply, and some assembly is required after delivery.
What sets the PTC400 apart is its center-post structure combined with a left-hand assist arm system. The bead-pressing and bead-lifting assist arm keeps both hands free during difficult mount/demount operations, especially on stiff sidewalls and run-flat tires. The swing-arm design holds the wheel more securely in a fixed centerline position, which helps reduce flex during rotation and improves consistency when working with wider or more delicate rims.
The machine uses a high-torque 110V electric turntable (7 RPM) paired with an air-operated bead breaker delivering 6,924 lbs of force, powered by an anodized aluminum cylinder for durability. An integrated flexible bead-blast system helps seat stubborn tires quickly, while the metal mount/demount head with replaceable plastic inserts reduces the risk of damage to alloy and coated wheels during repeated use. A full support kit is included, featuring a filter/regulator/lubricator unit, tire tools, lube bucket, and brush, ensuring the machine is ready for daily shop operation.
This model is best suited for tire shops, dealerships, and automotive service centers that regularly handle modern wheel designs and need a more controlled, assist-arm-equipped tire changer that improves efficiency and reduces technician strain during high-volume work.
