PSI?

[CamaroCrazy7]

hi guys this may be a stupid question but i am wondering what you guys keep your tires pressure at?

[Mod007]

34psi, when its just me driving. If I go on a trip and have extra people and cargo 36psi.

ok cool, i was wondering because it says the max is 50 psi on the tires so i thought maybe u should keep it close to that

I keep mine at 36psi. One of my tires got down to 33 psi and OnStar sent a diagnostic and said I need to add air...lol!

I also had gotten an email from onstar and said that the tire pres. should be at 36 psi, so I pressured them up to that. I was woundering about the pressure also since all the other vehicles that I have driven in the past were 32 psi.

check the sticker on the driver's door jamb. i think it requires 36 or 37 cold. mine were delivered a bit low and I haven't put my gauge on them yet; however I will very soon as it feels a bit mushy.

when in doubt, follow the instructions.

36 psi is for a full load. That’s a full tank of gas all fluids toped off and two adults and two children in the car. The more air you put in the car the bumpier your car will ride. Just remember you add air when you add weight.

Also SWHCPA is right, you always check your air when its cold like first thing in the morning "before" you drive it... Even driving two miles down to the gas station will increase your tire pressure because friction creates heat and heat increases air pressure.
