刚才发现外胎被划破了大约2厘米的口子，但没有穿，然后感觉胎有点瘪，但是看了看其他人的车，好象也差不多，我也不知道是不是自己神经过敏还是真的有问题？应该去GARAGE检查一下吗？今天所有的GARAGE 都休息！谢谢谢谢谢谢！！！！！

Folks

Use a tire gauge (轮胎气压表) to measure the pressure. You can not judge it by looking at the appearances.

The correct pressure should be between 32psi to 35 psi for cars/mini vans.

If the "damaged" tire is measured much less than the other three, then you will have to change that tire. Otherwise, you can continue to use it.

Then,What's the best pressure for compact car folks,please?

Folks

the best pressure varies:

1) in winter: 35psi -- this is because extreme cold temperature will lower the pressure, thus cauing excessive consumption of gas. You should check the pressure at least once a month, especially on a very cold morning (before you drive the car). Tires must be measured when tires are cold.  If you need to pump in more air, you need to drive slowly and not over 5 kms. Otherwise, the heat will increase the pressure and make the reading inaccurate.

2) in summer - 33 psi - this is because the extreme heat will increase the pressure even more. So let out some air from your tires. Otherwise, they may explode under very hot weather.

应该去GARAGE检查一下吗？
No, garage cannot prodict when the tire will be flat. They will suggest you if you need change according to the depth.
You can check yourself, if the depth is under 2mm, it's ok. otherwise, you need change it.
