After completing fitting, first release clamping claws. Inflate tire (without valve insert).

Increase pressure up to 3.3 bar (330 kPa) in steps. Do not further increase the pressure if the tire beading does not fully slip over the edge of the rim.

Release air and force off tire beading again. Coat rim flange again with tire mounting paste.

Inflate tire to 3.3 bar. When the tire beading rests correctly on the bead seats increase the pressure to max. 4.0 bar so that the tire "fits snugly".

Screw in valve and correct tire pressure.
