Toe measures the amount in which the front tires and
wheels are turned in or out (5) from a straight-ahead
position (4). When the tires and the wheels are turned
in, toe is positive(+). When the tires and the wheels
are turned out, toe is negative(-). the actual amount of
toe is normally only a fraction of a degree. The
purpose of toe is to ensure that the tires and the
wheels roll parallel by compensating the· slight
tolerances that exist within the suspension
components.

You can also measure total toe, which is the
relationship or difference .between the front toe
dimension (1) and .the rear toe dimension (2). Total toe
indicates the tire-to-tire relationship, but does not
indicate the relationship of a tire to the vehicle
centerline. Toe also serves to offset the small
deflections of the tire and the wheel support system
which occur when the vehicle is rolling forward.
Suspension
In other words, even when the tires and wheels are
set to toe in slightly when the vehicle is standing still,
ttie tires tend to roll parallel on the road when the
vehicle is moving. Toe affects tire wear.
