5 - Belt . This is a non­flexible circumferential structure
comprising cross-plys at very low angles, positioned be-
low the tread, to stabilise the casing in the footprint area.
6 - Centring band . This is a small mark that indicates the
circumference of the upper part of the bead and is used
as a reference to control correct tyre centring on the rim
after mounting.
7 - Protective band . This is a circumferential marking in the
area of the sidewall which is more exposed to accidental
rubbing.
8 - Sidewall. This is the area between the shoulder and the
centring band. It consists of a more or less thin layer of
rubber, which protects the casing plys from lateral impact.
9 - Liner
This is a vulcanised, compound layer, imperme-
able to air, inside tubeless tyres.
10 - Filling This is a generally triangular rubber profile,
above the side ring; it provides rigidity for the bead and
gradually offsets the abrupt uneven thickness caused by
the side ring.
11 - Flap . This is the part of the casing ply around the side
ring and placed against the casing, to secure the ply and
prevent it from slipping.
12 - Foot . This is the innermost layer of the tread in contact
with the belt, or if the latter is not present (conventional
tyres) with the last casing ply.
13 - Shoulder This is the most external part of the tread,
located between the corner and the start of the sidewall.
14 - Bead . This is the part that joins the tyre to the rim. The
bead point (a) is the inner corner. The spur (b) is the inner
part of the bead. The base (c) is the area resting against
the rim. The groove (d) is the concave part against which
the rim shoulder rests.
Tube type tyres. As a tyre has to contain pressurised air for
a long period of time, an air chamber is used. The valve
for adding air and maintaining, controlling and restoring
air pressure is part of the chamber in this case.
Tubeless tyres. Tubeless tyres consist of a tyre with inner
sidewall lined with a thin layer of special impermeable
