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.
• 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 finish
inflating and completely settle the beads in their
seats on the rim.
Beading tubeless tires is sometimes difficult 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 floor in a vertical position and 'bounce' it while
introducing air with the pedal control or with the inflator
gauge (Figure 5.6-1).
Beading with the GP device (if present):
The machine can be provided with a GP device,
necessary for bead seating of tubeless tires.
Proced as follows:
(Figure 5.6-2)
• If possible lock the wheel from inside. Outside
locking reduces efficiency of the bead seater.
• Connect the inflation hose to the valve stem (1).
• Lift the tire with both hands so that upper bead is
sealed to the rim edge (Fig. 5.6-2).
• Press the inflation 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.
• Complete inflation as described at the beginning of
this section.
(Figure 5.6-3)
WHEN OPERATING THE BEAD SEATER AND
INFLATOR IT IS MANDATORY TO WEAR EAR
PROTECTORS AND SAFETY GLASSES TO
PREVENT CONTAMINATION FROM NOISE, DUST
AND CHIPS BLOWN BY THE AIR JETS.
