天冷了可以調低胎壓嗎？
Can you lower the tire pressure when it's cold?
首先天冷的時候調低胎壓是不對的，之所以有這個說法，是在雪地越野和沙漠越野的時候采用。因為降低輪胎的胎壓，輪胎與地面接觸面積就多，可以更好的在雪地和沙漠脫困和行駛。但是對于正常行駛的時候，天冷的時候是不能調低胎壓，反而應該調高。因為物理上有個熱脹冷縮的原理，冬季氣溫降低，輪胎內的氣體相比夏天的時候，雖然量是一樣的，但是輪胎氣壓更低，所以應該要調高氣壓。
First of all, it is wrong to lower the tire pressure when it is cold. The reason for this statement is that it is used in off-road snow and desert. Because the tire pressure is reduced, the contact area between the tire and the ground is more, which can better get rid of difficulties and drive in snow and desert. However, for normal driving, the tire pressure cannot be lowered when it is cold, but should be increased. Because there is a physical principle of thermal expansion and cold contraction, the temperature decreases in winter, and the amount of gas in the tire is the same compared with that in summer, but the tire pressure is lower, so the pressure should be increased.
因為天冷了胎壓本來就比夏天低，還調低胎壓，輪胎就會過癟。雖然抓地力好了，但是也增加了油耗。更嚴重的是，因為長時間的低壓行駛，輪胎的負荷增加，胎壁就容易老化，增加爆胎的風險。所以冬天應該把胎壓升高，一般是按照說明書上的標準胎壓，升高0.1~0.2Bar。另外每款車的胎壓是不一樣的，不是大家通常說的2.5bar，也不是什么區間，在說明書上有嚴格的標注。說明書那么厚很少有人看，其實每輛車的車門側都會有一個標簽，有的是在油箱蓋上，自己可以找找。上邊標注的都是正常溫度時候的胎壓，所以夏天調低0.1~0.2bar，冬季調高就行。
Because it's cold, the tire pressure is already lower than that in summer. If you lower the tire pressure, the tire will be too flat. Although the grip is good, it also increases fuel consumption. More seriously, because of long-term low-pressure driving, the tire load increases, and the tire wall is easy to age, increasing the risk of tire burst. Therefore, the tire pressure should be increased in winter, generally by 0.1 ~ 0.2bar according to the standard tire pressure in the manual. In addition, the tire pressure of each car is different. It's not the usual 2.5bar, nor is it a range. It's strictly marked in the manual. The manual is so thick that few people read it. In fact, there is a label on the door side of each car. Some are on the fuel tank cover. You can find it yourself. The tire pressure marked above is the tire pressure at normal temperature, so it can be reduced by 0.1 ~ 0.2bar in summer and increased in winter.
有的車因為前后使用的輪胎不同，所需的壓力不同。比如冷車的時候，通常的乘坐人數只有兩個人和一個包，或者只有一個人，那么前后兩個的胎壓都是1.9bar。如果經常滿載，或者要滿載行駛很長的距離，就要調高胎壓，前2.1，后2.8，因為后備箱還有東西，后座的人多，后輪胎的壓力就更大。
Some cars require different pressures because the front and rear tires are different. For example, when the car is cold, the usual number of passengers is only two people and one bag, or only one person, so the tire pressure of the front and rear is 1.9bar. If you often drive with a full load, or if you want to drive a long distance with a full load, you need to increase the tire pressure. The front 2.1 and rear 2.8, because there are still things in the trunk and there are many people in the back seat, the pressure of the rear tire is even greater.
