First of all, the number 8 on the outside of the rear wheel of an automobile is generally used for cars, performance cars, supercars and racing cars, especially supercars and racing cars. This is because there are many corners on the track, and the pursuit of more extreme corner driving requires a strong grip. Therefore, the rear wheel of the car will be set in the shape of the outer eight, which is generally not adopted by ordinary family cars.
The number 8 on the outside of the rear wheel of the car is a setting to improve the handling of the car, and naturally it does not need to be adjusted. However, this modification is very unsuitable for daily vehicles, because the setting of foreign characters will make the vehicle turn heavy. When driving in a straight line, the contact area between the tire and the ground is small and the braking distance is long, which is easy to aggravate the wear of the tire.
