GLOSSARY

Tyre
The tyre is a combination of: I-tyre, II-rim (wheel), III-inner
tube (in tube-type tyres), IV-pressurised air
The tyre must:
- support the load,
- ensure the transmission of the drive forces,
- steer the vehicle,
- contribute to roadholding and braking,
- contribute to the vehicle s suspension.
I - Tyre. The tyre is the main element of the wheel-tyre combina-
tion which is in contact with the road and is therefore required
to withstand the internal air pressure and all the other stresses
generated by use.
A cross-section view of the tyre shows all its constituent parts:
1 - Tread. It is so-called because it comes into contact with
the ground as the wheel turns. It consists of a rubber blend
and of a "pattern" designed to ensure both good resistance to
abrasion and a good grip on the ground in wet and dry condi-
tions, as well as low running noise.
2 - Edge or reinforcement. A woven metal or fabric insert on the
outside of the bead; it protects the carcass plies from rubbing
against the rim.
3 - Carcass. It provides the resistant body of the tyre and
consists of one or more layers of rubber-coated fabric, or
plies. The way in which the plies which make up the carcass
are arranged gives the name to the tyre s structure. There are
the following different structural types:
Bias ply. The plies are laid at angles and arranged so that
the strands in one ply form a criss-cross pattern with those of
the next ply. The tread, which is the part of the tyre touching
