put the tyre inclined against the wall, press out the rim towards
the wall to make the tyre cavity completely free and bring the in-
ner tube into the tyre cavity having taken the tube at the valve
side;
insert the valve into the valve hole and fix it with a nut; in doing
so, see for the correct position of the valve, do not admit its
warping; Put the inner tube fully on the rim, pull the rim and in-
flate the tube in order to avoid the possibility of its jamming be-
tween the tyre shoulders and the rim;
put the tyre on the floor. At the opposite side of the valve, insert
both tyre irons in 250-300 mm from each other in a way ensur-
ing their reliable grip on rim lip and introduce the tyre shoulder
behind the rim lip by pressing the tyre irons down;
holding one tyre iron in such position, take out the second tyre
iron and insert it in 50-100 mm from the first one so that it will
grip the lip and introduce the tyre shoulder behind the rim lip by
pressing the tyre iron down. The mounting will be much easier if
you press the tyre by foot at the same time. In order to facilitate
the process of introduction of the tyre upper shoulder, sink in by
feet into the rim groove the tyre part being opposite to the
shoulder introduced;
the installation shall be finished by two tyre irons at the valve;
Inflate the tyre to the normal pressure, then fully release air from the tyre, inflate it again to
the pressure of 0.28 MPa (2.8 kgf/cm
2
), keep this pressure until the tyre shoulders seat on
the rim shelves; then release air until the recommended pressure in the tyre gets estab-
lished. Inflate the tyres within a protective fencing (area).
Dismantle the tyre from the rim in the following sequence:
fully release air from the tyre;
take off the tyre shoulders from both conic rim shelves by
means of the fork end of the first tyre iron and the bent end of
the second one. Take off the shoulders from the shelf being op-
posite to the valve hole first, in the following sequence:
