请问胎压

[yangf0704]

请问标准是32psi的轮胎，胎压低于多少就需要充气？



另外，每次充好气后，过一个星期左右胎压只有26，这样正常吗，四个胎都是这样



谢谢

Possible of a slow leak, better go check to make sure.

非常不正常啊，保持30+才对

Did you test the pressure when the tires are cold? Tire pressure is higher (4-5 psi) when tires are warmer after driving for a while.

alloy rims?

是alloy rims。都是在早上量的。现在问题是4个胎都是一样的。以前还发生过几次其中一个胎瘪了，但是重新打好气又没问题的情况（不是同一个）。我都有点怀疑是不是车停在外面有人在放气

years ago costco tires department could repair(beef up) the alloy rims if they had slow leakage. i used that service once, $8 per tire. i am now sure if they still do it now or not.

Seal on alloy rims likely is causing air leak

一个星期后26，之后呢？是保持在26还是更低了？



来我们这里查一下吧~~
