Nitrogen is the inert gases, low expansion coefficient, not easily with the environmental temperature rise for a long time, can maintain normal tirepressure, greatly reduce the flat tire.
氮气是惰性气体，膨胀系数低，不轻易随环境温度上升而上升，可较长时间维持正常胎压，大大降低爆胎几率。

It can also be a car that has built-in sensors to alert the driver when the tirepressure is low.
它还可以是装有内置传感器的汽车，一旦胎压不足，传感器就会向驾驶员发出警报。

Incorrect tire inflation can cause many types of steering and braking difficulty. lowpressure will cause hard steering frontwheel shimmy steering kickback and tire squeal on turns.
