Why is the rear tire a bit splayed?

1. The four wheels of the car are mounted on the suspension. The angle of the wheel directly affects the driving state of the vehicle.

2. The automobile manufacturer has designed and required the angle of suspension and chassis of each car. Four-wheel alignment is to calibrate the positions and driving angles of four wheels to the factory settings. It varies from car to car.

3. Only the high-quality and high-precision positioner can accurately detect the angle between the wheel and the chassis. Whether the angle is normal or not is not judged by vision.
