外顷角（英语：camber angle）乃正面望去轮胎与车身的角度，向外倾斜为正外倾角，向内倾斜为负外倾角。基本上，正外倾角的设置有较佳的灵活度，而负外倾角具较稳定的直进性。按照轮胎坐标系的规定，汽车向右前方行驶时，右前轮有正外倾角，左前轮有负外倾角。

Camber angle is the angle made by the wheels of a vehicle; specifically, it is the angle between the vertical axis of the wheels used for steering and the vertical axis of the vehicle when viewed from the front or rear. It is used in the design of steering and suspension. If the top of the wheel is farther out than the bottom (that is, away from the axle), it is called positive camber; if the bottom of the wheel is farther out than the top, it is called negative camber.
