一天后轮胎气压降低２ psi ，轮胎是不是有问题 michaelusa22021-09-03 22:45:44

最近一直在家工作，前天偶然发现一个轮胎看起来气不足，量了一下，大概１８psi，打足气到３１psi，今天再查下大概是２８psi，轮胎是新换的，是不是轮胎在漏气？现在疫情，去shop检查比较麻烦，是请他们来上门pickup;

thank you very much for your time and any input

call them and let them take care of it

可能是气温或者轮胎温度不一样的原因，可以过两天再测试一下

尽量同样的条件：气温， 阳光照射否？没有开动之前

漏气了，不是valve就是tire lips没装好

差不多情况，没开车前测的

ok, seems new tire not been installed properly

Soapy water spray can easily show the leak

got it, will do, yes, coz only need apply on valve/lip area

however, anyhow, needs to bring to shop to fix it

I would also spray along both tire lips, interior and outerior

yeah, interior is hard for me, coz, needs lift car a bit

很多tire shop 都免费检查，如果有钉子，取出来也不收费

慢煞气。有没有仔细检查了轮胎？有没有钉子？ 最好去轮胎店查查， 他们很容易查出来的。

What is accuracy of your tire pressure gauge? (NT)

It’s doable, if it’s at the front steer it all the way

Its accuracy doesn’t change overnight.

I fixed mine longtime ago by myself

yeah, but, I am just lazy :)

it is new tire, the shop should fix it without charge

both meter and tire charger shows psi down

thanks for all the suggestions, helped me a lot ...
