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

　　有網友問到“普通大約幾行程需求改換輪胎？”事實上，輪胎的改換并不是由行程來決議，而是由輪胎的磨損水平來決議能否需求改換。假如輪胎胎面磨損到達一定水平，影響了行車平安，則必需改換，跟行駛里程沒太多聯絡。

　　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.

　　不過輪胎倒是有一定的保質期，超越保質期的輪胎好不要運用。超越保質期后，雖然胎面的磨損還沒到達改換的水平，但是內部材質（例如橡膠）曾經老化，這時應該及時改換輪胎。

　　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、需求依據不同時節調理不同的胎壓？

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

　　有網友提到，夏天輪胎氣壓應該低點，而冬天應該高點，這種理論能否正確的問題。輪胎的氣壓，在氣溫高的時分會增大，氣溫低的時分會降低，這是物理上的變化，也就是熱脹冷縮的原理。

　　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.

　　但在日常用車過程中并不需求依據時節變換而人為的升高或者降低氣壓。這是由于外界溫度的變化招致胎壓的變化幅度均在輪胎的平安胎壓極限之內，只需堅持在廠家給出的規范胎壓左近就能夠了，夏天胎壓過低有時分反而會惹起不測。

　　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.

　　我們此前《真相俠》系列也做過相關測試，在夏天為輪胎充氣時并不需求降低廠家規則的規范氣壓來避免車輛爆胎，只需依照空載時的輪胎氣壓規范為車輛的輪胎充氣就能夠了。

　　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.

　　總結

　　summary

　　要防止日常用車過程中胎壓呈現異常，勤檢查胎壓是一種辦法。不過關于那些在路上扎到釘子，可能輪胎漏氣是在大名鼎鼎中停止的，一不留意就會終招致爆胎，白白糜費了一條輪胎，這時有一個胎壓監測系統就顯得非常重要。目前原車裝備胎壓監測的車型并不多，但車主還是能夠選擇自行加裝。專家倡議，假如條件允許還是裝置胎壓監測系統，選購胎壓監測儀時好選擇知名品牌，這樣售后效勞會有保證。在選擇的時分，也要留意選擇質量較好的芯片。

　　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.
