In high-speed driving, a sudden tire burst is a very dangerous thing, which may threaten the safety of the people on the car. How to prevent tire burst in normal time? What kind of inspection should be done before driving? Huasheng Audi maintenance consultant sorted out the following information for the owner's reference!

胎压问题是祸根

Tire pressure is the bane

爆胎的祸根在于轮胎气压不足。车辆缺气行驶时，随着胎压的下降，轮胎与地面的摩擦会成倍增加，胎温急剧升高，轮胎变软，强度下降。此时车辆若高速行驶，就可能导致爆胎。胎压过高也不行。车辆的充气压力高于标准值，随着行驶里程的增加，轮胎的温度会慢慢地升高，当气压高于轮胎的压力承受极就容易形成爆胎。

The cause of a flat tire is the lack of tire pressure. When the vehicle is running under air shortage, with the decrease of tire pressure, the friction between the tire and the ground will increase exponentially, the tire temperature will rise sharply, the tire will become soft and the strength will decrease. At this time, if the vehicle runs at a high speed, it may cause a tire burst. The tire pressure is too high. The inflation pressure of the vehicle is higher than the standard value. With the increase of mileage, the temperature of the tire will slowly rise. When the air pressure is higher than the pressure limit of the tire, it is easy to form a flat tire.

胎面受损很危险

Tread damage is dangerous

不好的驾驶习惯，是很容易使轮胎受损伤的。轮胎表面的损伤主要分为两种：胎冠损伤和胎侧损伤。如果是胎冠损伤的轮胎修补后更好作为备胎，如果一定要使用不要放在转向轮，要放在后轮，这样危险性较小一些，同时注意轮胎压力要充标准气压。胎侧损伤的轮胎就不要再使用了。

Bad driving habits can easily damage the tires. There are two kinds of surface damage: crown damage and sidewall damage. If it is a tire with damaged crown, it is best to use it as a spare tire after repair. If it must be used, it should not be placed on the steering wheel, but on the rear wheel. This is less dangerous. At the same time, pay attention to the tire pressure to be filled to the standard pressure. Do not use a tire with damaged sidewall.

轮胎也有自己的寿命，磨损到一定极限的轮胎就不能再将就使用了。是轮胎的使用寿命到达极限后，轮胎就会老化导致橡胶层与钢丝层分离;其次是轮胎的花纹使用到极限后，钢丝层就会磨断，如果继续行驶，就会发生事故。

Tires also have their own life. If they are worn to a certain limit, they can no longer be used. First of all, when the service life of the tire reaches the limit, the tire will age, leading to the separation of the rubber layer and the steel wire layer; second, when the tread pattern reaches the limit, the steel wire layer will be worn off, and if you continue to drive, accidents will occur.

轮胎定位很关键

Tire alignment is critical

一般情况下，汽车行驶一万左右，就要到服务站去做一次定位检查，如果四轮定位失准，行驶当中会加剧轮胎的磨损，从而导致温度升高而爆胎。现在有的司机在行驶一段时间后，愿意把四个轮胎互相换一下，继续行驶，司机本意是想延长轮胎的使用寿命，可如果轮胎有偏磨，就会发生方向跑偏，噪音增大，严重的就会发生车毁人亡的事故。

Generally speaking, when a car travels about 10000 km, it is necessary to go to the service station for a positioning inspection. If the four-wheel alignment is inaccurate, the tire wear will be aggravated during driving, which will lead to the temperature rise and tire burst. Now some drivers are willing to change their four tires after driving for a period of time. The original intention of the driver is to extend the service life of the tires. However, if the tires are worn off side, they will run off side, increase the noise, and in serious cases, they will be killed.

当然，对于那些驾驶习惯特别好的司机，即使已经跑了7万-8万，轮胎经检查还非常好，如果想换胎行驶，就可以在旧胎中挑两个好一点的放在后轮上，前面两个换成新的，这样也可以继续行驶。

Of course, for those drivers with good driving habits, even if they have already run 70000-80000 km, their tires are still very good after inspection. If they want to change their tires, they can choose two better ones from the old ones and put them on the rear wheels, and replace the front two with new ones, so that they can continue to drive.
