air chamber (or tyre in the case of tubeless tyres).
It consists of three parts: the valve closing cap (a)
(to protect the internal mechanism from dust and
guarantee air tightness), an internal mechanism (b)
and the base (c) (the outer lining).
Tubeless Inflater. An inflation system which simpli-

Beading. Operation which takes place during infla-
tion and ensures perfect centring between the bead

Bead pressing gripper. A tool intended for use when
mounting the upper bead. It is fitted so that it grips
the shoulder of the rim and holds the tyre upper
bead inside the rim well. It is generally used for
mounting low profile tyres.
Air delivery regulator. Union allowing regulation of
the air flow.
Bead breaking. Operation that allows the tyre bead
