上周五打足气到 31 psi,一直没开过, 今天用自动打气机(可以设定气压的那种)再次打气,起始气压好象是28psi。看来轮胎问题不大(今天天气比较凉快,可能是个原因)。

有个疑问,上星期发现问题的时候,轮胎气压好像18psi左右,是因为新轮胎装上的时候就一直没有打足过气?(半年前新换的轮胎,也一直没有测过气压)

thanks again for your time and any input

 

(原帖)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;

28PSI 太低了, 那18PSI的车, 你的TPM没亮?

你会卸轮胎吗?如果会,卸下来放在澡盆里加水一看就知道了。

你以前也发同样我问题?清晨量。2psi不是事。
