實際上，汽車的胎壓是非常重要的東西，和車子的性能行駛等都是有著密不可分的關系。那么既然汽車胎壓很重要，多少算合適呢？高點還是低點呢？
In fact, the tire pressure of the car is very important, and the performance of the car, etc., are closely related. So since tire pressure is so important, how much is appropriate? High or low?
如果胎壓高了，那么汽車與地面的接觸面積將會變少，減少了摩擦力，就增加了輪胎中間部分的損耗，降低輪胎的使用壽命，并且也會更容易發生爆胎事故，特別是夏季。
If the tire pressure is high, the contact area between the car and the ground will be less, reducing the friction, increasing the loss of the middle part of the tire, reducing the service life of the tire, and it will be more prone to tire accidents, especially in summer.
高胎壓還會增加汽車各種系統的負擔，縮短汽車的使用壽命。由此看來，很多人認為的高胎壓讓汽車跑起來阻力小從而達到省油的目的那就是一個錯誤的認知了。
High tire pressure can also increase the burden on a car's various systems and shorten the service life of the car. Therefore, many people think that high tire pressure makes the car run low resistance to achieve the purpose of fuel economy that is a mistake.
低胎壓確實能夠保證汽車輪胎與地面的受力面積增大，從而能夠達到一個增大摩擦力的效果，保證汽車在行駛時及時遇到了突發狀況或者是急轉彎也能夠及時剎車然后安全度過。但是對汽車會顯得吃力，而且也會增加耗油量。長期低壓，輪胎兩側會磨損，同樣也會增有爆胎的概率。
Low tire pressure can indeed ensure that the force area of the tire and the ground of the car increases, so as to achieve an effect of increasing friction, to ensure that the car can brake in time when encountering an emergency situation or a sharp turn and then safely pass through. However, it is difficult for cars and increases fuel consumption. Long-term low pressure, tires will wear on both sides, also will increase the probability of a flat tire.
由上可知高胎壓不安全，那么低胎壓，肯定也不會安全到哪里去。另外需要明確告訴的一點就是：高胎壓并不能夠達到一個省錢的目的，這是很多人都會存在的一個盲點。
From the high tire pressure is not safe, so low tire pressure, certainly not safe where to go. Another thing to be clear about is that high tire pressure is not a money-saver, and it's a blind spot that many people have.
那么到底多少的胎壓才算是合適呢？
濟南奧迪汽車維修人員告訴您，如果用肉眼看到的話就是4-5個齒著地的情況下算是合適的，這樣的胎壓，能夠使這個輪胎平面都著地，不會出現不均勻。這樣汽車的輪胎就會牢牢的抓住地面，增加輪胎的壽命，也會減少爆胎的危險。
So how much tire pressure is appropriate? Ji 'nan Audi car maintenance personnel tell you, if you see with the naked eye is 4-5 teeth on the ground is appropriate, such tire pressure, can make the tire plane are on the ground, there will be no uneven. This gives the car's tires a firm grip on the ground, increasing the life of the tires and reducing the risk of a flat tire.
Car tire pressure is very important. How much is appropriate? The above has explained the content, if the above description of this method you feel that you do not understand, you can come to the website www.junwumy.com for consultation at any time!
