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 nozzle
(Figura 5.6-2).
