Tire Removal With A Fitting Machine:

IMPORTANT: Gap between unseating tool and rim flange must not exceed max. 2 cm.
Do not position unseating tool in area of valve (damage to wheel pressure sensor). Turn wheel through 180° and position unseating tool on opposite side.

Pull off balance weights on rim and clean rim to remove large pieces of dirt.

Unscrew valve insert, release air.

If tire beads are stuck, first release the tire with the pressing-off horn at several points of the wheel before actually pressing off, applying tire mounting paste between the tire and the rim flange. Only then press off the tire completely.
