The Sun STC5545 is a tyre changer designed for all workshop types.

STC5545 Tyre Changer


The Sun STC5545 is designed for all workshop types, for handling standard manufacturer, run-flat and ultra-high profile tyres.


It offers a high productivity speed via the built-in ProSpeed inverter technology which automatically controls the speed of the turntable dependant on the torque required when mounting/demounting the tyre, along with a large 24-inch outer clamping range.


*Please note that this image is shown with the optional Plus Kit. The Plus Kit does not come as standard with the STC5545.


Suggested Package

Create a wheel service equipment package for your workshop by adding either the Sun SWB300L wheel balancer or the SWB340L to the STC5545 tyre changer.

  • Adjustable bead breaker length: The three position adjustment provides easier use across a broader range of wheels
