I'm wondering how much p.s.i the tires on our cars should be at. Today when I came out from the house I looked at my tires and I think they are kind of low. I know the max on them says 50 but 3 are at 35 and one is at about 29. What p.si do you have your tires at? Or how much is what's supposed to be on there. I'm runnint stock 225/60/16
