During the manufacturing process, tire characteristics are measured. Tires are then
mounted on the vehicle as matched sets to help reduce conditions such as pulling or
drifting. If the wheels are replaced or refinished before vehicle delivery, it is important
that the tires remain on the vehicle in the same location and in the same direction
of rotation.
Please refer to the following procedure to ensure that the original tires stay in the same
location on the vehicle.
All 2005 ± 2006 model year Lexus vehicles.
1. Mark the tire installation position on the inward facing tire sidewall.
Example: Front Right = FR, Front Left = FL, Rear Right = RR, Rear Left = RL
2. Install the original tires on the new or refinished wheels with the marked side
facing inwards.
3. Place the tire/wheel assemblies on the vehicle in the marked positions.
NOTE:
Torque the wheel nuts to the proper torque value in sequence.

REPAIR MANUAL SUPPLEMENT: VEHICLE PULLING TO ONE SIDE ± ST004-01 RevisedDecember 21, 2001
Page 4 of 11
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.

Direction of Tire Rotation) Hard
Part
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
