1. In XX years or xx10,000 kilometers, do you need to change the tire once?

　　有网友问到“普通大约几行程需求改换轮胎？”事实上，轮胎的改换并不是由行程来决议，而是由轮胎的磨损水平来决议能否需求改换。假如轮胎胎面磨损到达一定水平，影响了行车平安，则必需改换，跟行驶里程没太多联络。

　　Some netizens asked, "How many journeys do you need to change your tires?" In fact, the change of tyres is not determined by the travel, but by the wear level of tyres. If the tire tread wear reaches a certain level, affecting the safety of driving, it must be changed, and there is not much contact with the mileage.

　　不过轮胎倒是有一定的保质期，超越保质期的轮胎好不要运用。超越保质期后，虽然胎面的磨损还没到达改换的水平，但是内部材质（例如橡胶）曾经老化，这时应该及时改换轮胎。

　　However, there is a certain shelf life for tires. It is better not to use tires that exceed the shelf life. After exceeding the shelf life, although the tread wear has not reached the level of replacement, but the internal material (such as rubber) has aged, at this time should be timely replacement of tires.

　　2、需求依据不同时节调理不同的胎压？

　　2. Different tire pressure should be adjusted according to different time periods.

　　有网友提到，夏天轮胎气压应该低点，而冬天应该高点，这种理论能否正确的问题。轮胎的气压，在气温高的时分会增大，气温低的时分会降低，这是物理上的变化，也就是热胀冷缩的原理。

　　Some netizens mentioned that the tire pressure should be low in summer and high in winter, whether this theory is correct or not. The pressure of tyres increases when the temperature is high and decreases when the temperature is low. This is a physical change, that is, the principle of thermal expansion and contraction.

　　但在日常用车过程中并不需求依据时节变换而人为的升高或者降低气压。这是由于外界温度的变化招致胎压的变化幅度均在轮胎的平安胎压极限之内，只需坚持在厂家给出的规范胎压左近就能够了，夏天胎压过低有时分反而会惹起不测。

　　However, there is no need to artificially raise or lower the air pressure according to the changing seasons in the daily use of vehicles. This is because the change of external temperature causes the change range of tire pressure to be within the limit of tire's safe tire pressure. Just stick to the standard tire pressure given by the manufacturer. Sometimes too low tire pressure in summer will cause unexpected results.

　　我们此前《真相侠》系列也做过相关测试，在夏天为轮胎充气时并不需求降低厂家规则的规范气压来避免车辆爆胎，只需依照空载时的轮胎气压规范为车辆的轮胎充气就能够了。

　　We have also done relevant tests in the "Truth Man" series before. It is not necessary to reduce the normative pressure of the manufacturer's rules to avoid tire burst when inflating tires in summer. It is only necessary to inflate the tires according to the no-load tire pressure norm.

　　总结

　　summary

　　要防止日常用车过程中胎压呈现异常，勤检查胎压是一种办法。不过关于那些在路上扎到钉子，可能轮胎漏气是在大名鼎鼎中停止的，一不留意就会终招致爆胎，白白糜费了一条轮胎，这时有一个胎压监测系统就显得非常重要。目前原车装备胎压监测的车型并不多，但车主还是能够选择自行加装。倡议，假如条件允许还是装置胎压监测系统，选购胎压监测仪时好选择知名，这样售后效劳会有保证。在选择的时分，也要留意选择质量较好的芯片。

　　In order to prevent abnormal tire pressure during daily vehicle use, it is a method to check tire pressure frequently. However, for those nails on the road, it is possible that the tire leak stopped in a well-known place. If you don't pay attention, it will eventually lead to a tire burst. White waste a tire. At this time, it is very important to have a tire pressure monitoring system. At present, there are not many vehicles equipped with tire pressure monitoring, but the owner can choose to install them by himself. Experts suggest that if conditions permit or install a tire pressure monitoring system, it is best to choose a well-known brand when purchasing tire pressure monitor, so that after-sales service will be guaranteed. When choosing, we should also pay attention to choosing chips with better quality.
