/kloc-what's with the car jitter of 0/20 yards?

It may be the poor dynamic balance of the two front wheels of the vehicle, and the following dynamic balance can be adjusted.

The wheel of an automobile is a whole composed of tires and wheels, but due to manufacturing reasons, the mass distribution of each part of this whole cannot be very uniform.

When the automobile wheels rotate at high speed, it will form a dynamic imbalance state, which will cause wheel jitter and steering wheel vibration when the vehicle is running.
