on a specific rim, to which the valve is directly fixed.
II - Rim (Wheel). The wheel is the rigid metal part which
connects the vehicle hub to the tyre, on a fixed but non-
permanent basis.
Rim profile. The rim profile is the form of the section in
contact with the tyre. It comprises different geometric
forms, which ensure: easy tyre mounting (bead inser-
tion in the rim well); safe driving, in terms of the bead
anchored in its seat.
The rim section shows its various parts: a) rim width – b)
shoulder height – c) tubeless anchoring (HUMP) – d) valve
hole – e) ventilation opening – f) off set – g) central hole
diameter – h) attachment hole centre to centre i) keying
diameter – j) rim well.
III - Air chamber (tube type tyres). The air chamber is a
closed ring-like rubber structure with valve, which con-
tains pressurised air.
Valve. The valve is a mechanical device to inflate/deflate
the tyre and maintain air pressure inside the 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 Inflator. Inflation system that makes the inflation
of tubeless tyres easier.
Beading. Operation which takes place during inflation
and ensures perfect centring between the bead and
the rim edge.
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 to
be detached from the rim edge.
