Many drivers have heard the tire's tire pressure adjustment according to the different time of temperature，But how to adjust the air pressure of tires in summer or winter is unclear，Only know that the air pressure of the tire is best 2.3 or 2.5。And now the temperature has dropped，Some people in winter will say that you want to reduce the air pressure of the tire，This can increase the contact area，Increase the grip of the tire。But is it safe to lower the tire pressure when it seabet iois cold? Actually，If you do not master the seabet iocorrect method of tire pressure，Don't adjust it。

First when it is cold when it is cold, it is wrong to lower the tire pressure，The reason why there is this saying，It is used。Because the tire pressure of the tire is reduced，The area of ​​contact with the ground is more，You can better get rid of and driving in the snow and desert。But for normal driving，When it is cold, you can not adjust the tire pressure，Instead, it should be raised。Because there is a principle of heat expansion and contraction in physics，Decrease temperature in winter，Gas in the tire compared to the summer time，Although the amount is the same，But the tire pressure is lower，So you should increase the air pressure。

Because the tire pressure is cold, it is lower than summer，Also low tire pressure，The tire will pass。Although the grip is better，But also increased fuel consumption。More serious is，Due to a long period of low pressure，Tire load increases，The fetal wall is easy to aging，Increases the risk of tire。So the tire pressure should be increased in winter，Generally according to the standard tire pressure in the instructions，Stepping 0.1 ~ 0.2bar。The tire pressure of another car is different，Not everyone's usually said 2.5Bar，No interval，There are strict marks in the manual。The manual is so thick that few people read，In fact, there will be a label on the side of each seabet logincar door，Some seabet ioare on the fuel tank cover，You can find it。The tire pressure marked on the normal temperature，So lower 0.1 ~ 0.2bar in summer，Just increase in winter。

Some cars are different because of tires used before and after，Different pressure required。For example, when the cold car is cold，Generally, the number of rides is only two and one bag，or only one person，So the tire pressure of the two front and back is 1.9bar。If you are full of full load，Or a long distance to driving for a long load，It is necessary to increase the fetal pressure，Ahead 2.1，Post 2.8，Because there is something on the trunk，More people in the rear seat，The pressure of the rear tire is even greater。

But this is just a reference，I still need to adjust the tire pressure according to the instructions on my car。Another，It is inevitable that the tire will be replaced，It is best to replace both wheels on the same side，Model and the original factory。I can't find it，The two tire models of the front or back should be the same，Then adjust according to the standard pressure on the tire。 (The content of the article is derived from the Internet，If you involve the copyright, please contact delete)
