Traction steer is a measure of the toe angle change in a suspension system when it is subject to a longitudinal force applied at wheel centre. Traction steer is measured as degrees of toe change per Kilo-Newton of force at the wheel centre, Deg/kN.

The name traction steer implies a forward force due to a forward driving force from the engine as shown in the image above. On most suspension systems it can be difficult to tune traction steers independently from brake steer.
