Comparison of structures and characteristics of tires
Radial tire
Structure
The cords of carcass (1) are arranged at right
q
angles to the center line of tread (T) (radially).
Tread (T) is stabilized and protected by several
q
strong belts (2).
Side wall (W) and tread (T) are independent
q
from each other.
Ground contact characteristics
Even if the tire is deformed by a load, it does
q
not move uselessly in ground contact and uni-
form ground contact surface is secured stably.
Deformation characteristics
Only side wall (W) is deformed as load is
q
applied and tread (T) made of strong belts (2)
keeps stability independently.

Bias tire
Structure
The cords of carcass (1) are arranged bias
q
from the center line of tread (T).
Side wall (W) and tread (T) are integral.
q
Ground contact characteristics
If the tire is deformed by a load, the ground
q
contact surface is also deformed, leading to
wasteful moves. As a result, the ground con-
tact surface becomes unstable.
Deformation characteristics
Side wall (W) which receives loads and tread
q
(T) move as one unit.
