Pump the tyre to the normal pressure, then fully release air from the tyre and pump again to the
pressure of 0.28 MPa (2.8 kgf/cm
2
), having held under this pressure until the tyre shoulders seat
the rim shelf; then release air until the recommended pressure in the tyre gets established.
Perform pumping of tyres within enclosing net (area).
Perform tyre dismantling 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 blade and the bent end of the second
blade. Perform taking off the shoulders first from the shelf being
opposite to the valve hole in the following sequence:
insert the bent end of the second blade between the shoulder lip
of the rim and the tyre and press out the tyre shoulder
downwards;
insert the fork end of the first blade into the gap generated
between the shoulder lip of the rim and the tyre so that the bent
end of the second blade should be in the groove of the fork blade;
press out the tyre shoulder downwards with the first installation
blade. Repeat the operations set forth in Items 1, 2, 3 over the
whole rim circumference to complete removal of the tyre
shoulders from the seating shelves;
insert the installation blades on both sides of the valve hole at the
distance of 100 mm and, pushing the opposite shoulder of the tyre
by feet into the installation groove of the rim, extract a part of the
tyre shoulder behinds the rim lip;
step aside from the part of tyre shoulder extracted over the
circumference for a distance where it is possible to introduce the
second blade without difficulties with the bent end between the rim
lip and the tyre shoulder, and again extract the tyre shoulder
behind the rim lip;
repeating the operation as per Item 5, take off the upper shoulder
of the tyre;
put the wheel at an angle in respect of the wall and extract the
inner tube;
