Toe-in is necessary because the wheels have a camber and therefore tend to roll along divergent arcs. Toe-in eliminates this tend.
ency and makes the wheels roll along parallel straight lines. Improper toe-in results in excessive tire wear and vehicle instability. Toe-in is equal to the difference between the distances A and B as illustrated in Figure 1; it ranges between 2 and 8 mm, depending on the vehicle model. It can be regulated by means of adjustable tie rods and the transverse centerlink, which are equipped with threaded ends.
