关于胎压的问题

[新手]

我的车标准胎亚应该是32，前几天天气热的时候量没有问题；后来天气一凉，有个轮胎就只有28了。后来天气又热了，再一量，又回到了31，也凑合了。

问题是：
1，28psi是不是也凑合开？会多耗很多油吗？胎压多少以下应该及时充气？
2，现在天气凉了，如果给轮胎打气到32，万一哪天天气再热了，庐山开车是否有爆胎的危险？
3，标准胎压是32，上限一般是多少？35？37？

谢谢

nothing is that strict. anywhere between 28 and 36 psi would be ok.

夏天要比冬天低点，冬天32是正常，夏天27就行了。

Hi, Friends, How can you guys measure your tire air presure? You go to the mechanic or you have some special devices can measure by yourself? Thank you!

a regular tie pressure gauge will do the job. according to the manufature tire press set the tire pressure at cold,it usually located on the door or beside the door. if you look careful on your tire, you will see it reads MAX PRESSURE XXPSI AT COLD.
