2. Relationship Between Tire Characteristics and Vehicle Pulling to One Side
When radial tires are rotating, they have the characteristic of generating force in the
lateral direction between the tire and the road surface. This lateral force is comprised
of two factors:
Ply±steer, which changes direction according to the rotation direction of the tires.
Conicity, which is generated in a fixed direction regardless of the tire rotation
direction.
If these lateral forces are too strong, vehicle pulling will occur.
A. Ply±Steer
Lateral force due to ply-steer is produced by the construction of the belts inside
the tire tread. With radial tires, the wire of the belt is slanted as shown in the
illustration below. Thus, it is in the lateral direction that tire tread easily changes
shape (stretches), and lateral force is generated between the tire and the road
surface in the lateral direction.

(Direction of Force Generation Varies
According to Tire Rotation)
NOTE:
Lateral force from ply-steer prevents vehicle drift caused by road slant, so in many
cases lateral force to the right is provided for left-handed steering vehicles.
B. Conicity
Conicity is lateral force resulting from uneven formation of the left and right sides
of the tire. The direction the lateral force is exerted depends on the hardness of
the side walls and the difference in height between the left/right sides of the tire.

NOTE:
In the case of vehicle pulling caused by tires, the lateral force which is exerted as a
result of conicity has the greatest effect. On a flat road, if the steering wheel is held
without exerting steering effort for 100 m (109 yards) when travelling at 100 km/h (62
mph), the vehicle may drift as much as 1.5 m (5 ft).
When vehicle pulling is due to conicity, the amount of drift can be reduced and the
direction of drift can be changed by changing the location of the tire or reversing
the tire when installing it on the wheel. Wheel

* Select a flat road where the vehicle can be driven in a straight line for 100 meters at a constant speed of
35 mph. Please confirm safety and set the steering wheel to its straight position. Drive the vehicle in a
straight line for 100 meters at a constant speed of 35 mph without exerting steering effort on the steering
wheel.
