This specially developed adapter set enables the secure and precise fixation of van and light truck rims with a large centre bore on tyre changers with central clamping of the M72Z and M74Z model ranges. The covered hub bore diameter range of 142 mm to 170 mm guarantees exact positioning and damage-free clamping of the rim onto the central clamping unit. The stable construction withstands the high forces involved in mounting and demounting commercial vehicle tyres and ensures a smooth workflow in professional workshop operation. The precise fit significantly simplifies the handling of heavy wheels and optimally extends the functional scope of the tyre changer.
