我买的二手车,买时气压29.5。气压计上没看到单位。这个冬天想着气不饱满,就当雪胎啦, S! {- D" |8 u
直到昨天去打气,实在不知道应该打到多少,检查轮胎,有一排字,不太清楚 “300kp(44psi) ...

打开你的后车门,上面一般都有各个轮胎的气压标准。气压29.5 psi对于一般轿车,1.5吨左右来说是非常好的。34 psi高了一点。气压高了,开起来颠簸,耗胎。气压低了,耗油。我一般一个季度检查一次气压。半年才需要补充一两个 psi.看你买什么气压计,我的有psi,还有一个什么单位的,忘了。
ususally around 30~32psi for family cars. some cars require different tire pressure for front and rear tires. make sure to check the manual before fill. 44psi on ur tire is for maximum weight load, not for everyday drive. 7 e2 c: W) x$ p ( U& Q# b1 k9 g( yunit of measure: I:psi, M:pa
Just don't run the fronts underinflated, or you'll roundoff the edges. 0 q8 ?2 c1 S/ j# H7 y
35 lb should be ok, but for performance driving use the maximum on the tires, around 40.7 g, A* \! C6 g7 Q; N6 `
Use the tires' recommendations not the car's.

手册直到最后一页才说:参考门上贴的标识,“Inflate temporary spare to 414kPa(60psi)”这句不太懂6 I) N5 {. w# Y b! n
门上找来半天,才看清:30psi

'Max. press on tire' is the recommendation for that tire's maximum pressue.7 j/ B" D3 e* m3 [( f/ v, g4 s
That is to mean the maximum pressure for that tire at it's operating temperature.. w$ W9 z, u. w+ u1 P
Tire pressure goes up slightly as the temperature gets up or after been driven for awhile and visa versa for the same cases.
