-
When trying to correct for pull/drift refer to the following conditions.
Vehicle will pull/drift:
-

-
toward the low side if vehicle is leaning.
Tire Lead
"Lead" is the movement or wander of the vehicle from a straight path on a level road with no pressure on the steering wheel.
Lead is usually caused by:
-
Incorrect wheel alignment.
-
Uneven or incorrect tire inflation pressures.
-
Damaged or worn tire construction.
The way in which a tire is constructed can produce lead. An example of this is placement of the radial belts. Off-center belts on a radial tire can cause
the tire to develop a side force while rolling straight down the road. If one side of the tire is a little larger in diameter than the other, the tire will tend
to roll to one side. This will develop a side force which can produce lead.
Switching directional tires front to rear or side to side may be done when attempting to diagnose a tire lead, pull or drift condition. After the test
procedure, the tires must be returned to their original position.
