Tire pressures?
 

Guys I was having trouble reading old school tire pressure gauge at gas station, how much is one block mark on the gauge that pops out?... And will it be ok to pump few more psi than it says?

There should be numbers on the gauge. If there aren't numbers, then the gauge is worthless.

And you can't pump a few more psi than the gauge says, because the gauge will increase to match, so it will always say what the psi is, not less.


Your tire pressures should be between 28psi to 36psi to prevent the TPMS system from showing an alarm. 32psi is the general ideal mark, however you can adjust the balance, economy, and grip of the car slightly by varying front vs rear tire pressures

Oh, like rear pressure slightly higher than front?

Yup.

Gauge at gas station, I suppose each mark blanco is 10 psi? Cuz there is no unit on that thing...

You can pick up an old fashioned hand gauge for $1 at most auto parts stores. I wouldn't trust any machine without a gauge unless you have your own gauge to back it up

I see

I'd recommend splurging on a $10 digital tire gauge, rather than the dollar stick type.

Are you talking about just a tire pressure gauge, or about one that's built into the air hose a gas station? Don't put too much faith in gauges or pressure settings in gas station air hoses. Even if they were OK when new, they're outside all the time and get knocked around by every klutz that comes along.

Also,

when buying a tire pressure gauge, stay away from the cheap "pen" style ones. I have never found one that was accurate. The average I see is like 10psi off in those:SHOCKED:

A quality digital gauge is the way to go. Digital gauges, the good ones, are pretty accurate. Or, a good old school gauge with a flexible hose. (not the crap they sell at vato zone)
