This is because when the car is turning, due to the centrifugal force, the car body will tilt, and the wheels and suspension on the outside will be squeezed and stressed, while the suspension and tire on the inside of the corner will be less stressed. At this time, it is assumed that the wheel with the original inclination angle of 0 will slip, the effective grip area of the tire will be reduced, the tire will be deformed and the handling ability will be weakened. Therefore, the tire is inclined to enhance the grip and handling stability when turning.
For ordinary vehicles, the deviation of camber angle from the original factory setting value will cause tire eccentric wear, aggravate tire wear and even lead to serious tire puncture.
Extended data:
The inward inclination of tires is one of the biggest characteristics of HellaFlush. Hellafush is an international appearance trend of modified cars, which is more and more popular and accepted by the public. Hellafush has tended to be a taste certification for all types of cars, regardless of wealth.
HellaFlush mainly means that the extension line of the hub or tire is flush with the extension line of the wheel cover, and the hub tire and the car body naturally become a whole and keep the same curve. In order to achieve this effect, you must lower your body as much as possible. There is no exact standard for lowering the car body here, because ordinary shock absorbers can't be compared with air suspensions, but there is a basic rule that there can't be a gap between tires and fenders. If you don't lower the car very, very low, it's just a flush, not HellaFlush.
