Toe Description. Pontiac Sun Runner - 4WD (Canada) 1998

For 1990-2009 cars

Toe is a measurement of the deviation of the front of the wheels from the geometric centerline.

The toe can be either positive or negative:

• | The toe is positive (+) when the wheels turn inward (toe-in) (2).

• | The toe is negative (-) when the wheels turn outward (toe-out) (1).

The toe usually measures less than 1 degree.

The toe serves the following purposes:

• | The toe ensures that the wheels roll parallel to each other.

• | The toe offsets the small deflections that are present in the wheel support system while the vehicle is rolling forward.

| The wheels may be set to toe in or out slightly when the vehicle is standing still, but the wheels will roll parallel to each other while the vehicle is moving.

• | The toe affects the tire wear.
