What is the purpose of front wheel toe-in?

[LeMaya]

The purpose of front wheel toe-in is to eliminate the adverse effects caused by wheel camber, ensure the wheels do not roll outward, prevent wheel sideslip, and reduce tire wear. The toe-in value can be adjusted by changing the length of the tie rod, typically ranging from 0 to 12mm. Front wheel toe-in refers to the distance difference between the front and rear edges of the front wheels in the lateral direction of the vehicle, or it can refer to the angle between the direction of the vehicle's movement and the plane of the front wheels, in which case it is also called the toe-in angle. Proper selection of the toe-in angle can allow the lateral forces caused by toe-in to counteract the thrust caused by wheel camber, thereby avoiding additional tire wear and power consumption.
