Tyre
A tyre consists of:
I-the actual tyre,
II- the rim
(wheel),
III-the air chamber
(in tube type tyres),
IV-pressurised air.
The tyre must:
- withstand a load,
- ensure driving power,
- steer the vehicle,
- aid handling and braking,
- aid vehicle suspension.
I - Tyre
The actual tyre is the main part of the
overall tyre in contact with the road and is therefore
designed to withstand internal air pressure and all
other stress arising from use.
A tyre section shows the various parts it consists of:
1 - The tread
. This is the part in contact with the ground
when the tyre rolls. It comprises a rubber compound
and a “pattern” that is suitable for ensuring good
resistance to abrasion and good grip in dry and wet
conditions, as well as quiet operating conditions.
2 - Edge or bracing
. This is a metal fabric or textile
insert, in the area of the outer bead part. It protects
the casing plys from rubbing against the rim.
