Balance weight is a must for every car
It is very normal to have a balance weight on the wheel hub, even a new car is no problem. Maybe some friends may have said it, if you talk nonsense, my car does not have a balance weight. In fact, it's not that there is no, but some balance weights are attached to the bright part of the wheel hub, and some are attached to the dark part of the wheel hub. Those friends who say there is no belong to the second situation.
The function of the balance weight is to make the wheel achieve dynamic balance, because with the current processing technology, it is difficult for the wheel hub and the tire to be 100% round. Moreover, no matter what material or process is used to make wheels or tires, although they look uniform to the naked eye, they are actually uneven in quality, that is, some places are heavy and some are light.
If such wheels and tires are directly mounted on a car, the driver may not feel anything at a slower speed, but once the speed is increased, the jitter from the steering wheel can be clearly felt. This is caused by uneven wheel weight. Drivers and passengers bring discomfort. If you do not make adjustments for a long time, it will also cause uneven tire wear, and even more serious damage to the suspension system, the driving safety will be affected at that time.
