The TC3000 Tire Changer from Hunter has a conventional swing-arm tower that can handle tires up to 44" in diameter and 15" in width. The TC3000 can be ordered with either a steel or polymer mounting head and also includes: A strong twin-cylinder tabletop clamping system helps to clamp evenly as the unit ages and wear tolerance increases. The clamping jaws can be clamped internally on wheels up to 22" in diameter or externally up to 20" in diameter. Nylon inserts protecting alloy wheels when clamping externally. A side shovel bead loosener containing a quick-exhaust air valve circuit, which can travel 15", eliminating the need to readjust for wider wheels. A foot-feathering pedal for safety for all bead-loosening functions. An inflation pedal and pressure gauge, located out of the way of the tire failure danger zone. An integrated pressure limiter that inflates tires quickly and prevents unsafe over inflation.
