How does a balance car inflate tires?

The tire inflation method of balance car:

The air nozzle of the tire is on the inner side of the tire, which can be inflated by connecting the ordinary air pump and the attached extended air nozzle. The appropriate tire pressure is about 35-50PSI to ensure the same tire pressure on both sides.

The tire material and size of the balance car can be said to be a key configuration of the balance car, because it involves the stability of the balance car, whether on ordinary roads or bumpy roads. Because the wider the tire, the better the stability and off-road performance, so many high-end balance cars will use solid rubber to make this tire.

The operation principle of balance car is called the basic principle of dynamic stability. The attitude state of the car body is judged by the built-in precision solid-state gyroscope, and the appropriate instructions are calculated by the precision central microprocessor to drive the motor of the balance car, so as to achieve the balance effect.
