Beading Tubeless: tires
Perform the beading with the wheel blocked on the tire
changer.
• Ensure that both the beads and the inside of the rim
are thoroughly lubricated.
• Screw the valve insert.
• Connect the compressed air hose to the valve
(2,Figure 5.3-2).
• Operate the compressed air to ensure the beads are
seated.
STOP THE COMPRESSED AIR AS SOON AS THE
BEADS GRIP THE RIM WELL.
• Place the wheel in a type approved cage to fi nish
infl ating and completely settle the beads in their seats
on the rim.
Beading tubeless tires is sometimes diffi cult because the
beads may be very close together (e.g. owing to incorrect
stacking) and so fail to seal against the rim properly.In this
event it may be helpful to place the wheel on the fl oor in a
vertical position and 'bounce' it while introducing air with
the pedal control or with the infl ator gauge (Figura 5.3-1).
Beading with the GP device:
The machine can be provided with a GP device, necessary
for bead seating of tubeless tires.
(Figure 5.3-2)
• If possible lock the wheel from inside. Outside locking
reduces effi ciency of the bead seater.
• Connect the compressed air hose to the valve (2).
• Lift the tire with both hands so that upper bead is sealed
to the rim edge (Fig. 5.3-2).
• Press the infl ation pedal down swiftly. The top bead is
already sealed by the lifting motion. The air from the
bead seater jets will rebound into the bottom sidewall
driving it into place and creating a seal.
STOP THE COMPRESSED AIR AS SOON AS THE
BEADS GRIP THE RIM WELL.
• Place the wheel in a type approved cage to fi nish
infl ating and completely settle the beads in their seats on
the rim.
