Tire Part |
Function |
| Tread(Belt) |
Wear
resistance, cutting resistance, impact
resistance, low thermal conductivity
are required since it has direct contact
with road surface |
| Carcass (Casing) |
Impact resistance,
fatigue resistance against bending and
stretching is important since it is
tire’s inner cord layer, which supports
the load. |
| Bead |
It is to embrace
the end of cord and to install the tire
to the ring, and composed of bead wire
and core rubber. |
| Ply |
A special cord fabric
located between tread and carcass. Absorbs
impact from the road. |
| Sidewall |
Side section of
a tire. Protects carcass and with its
bending and stretching movement, provides
comfort of driving. |
| Shoulder |
Connecting section
of tread and sidewall. Good appearance
and good thermal conductivity is important
quality. |
| Chafer |
Protects the cord
by preventing ring and cord from direct
contact. |
| InnerLiner |
Special rubber layer
forming inside of a tubeless tire designed
to inhibit loss of air pressure. |
