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. l# ]! D$ L) ~; W$ |) Y7 s8 c$ K

spare tire 是 袖珍型的,直徑也小,60 psi 是對的,否則 steering 要出大問題了。但也不能作高速行駛用。4 E. Q. u( x4 u) \8 S' w' G6 o. L' T

sorry, I can't find the tires' recommendations, I just saw the max press on tire. they are "good year" tires

'Max. press on tire' is the recommendation for that tire's maximum pressue. # Y c( ~" G& F A That is to mean the maximum pressure for that tire at it's operating temperature. 9 @# I( E0 g/ y. S0 ]8 ]6 ITire pressure goes up slightly as the temperature gets up or after been driven for awhile and visa versa for the same cases.
