RE: Tire Pressure for 2002 Chevy Cav.
44 psi. . as stated above, always run tires according to their requirements printed on the tire sidewall.When you run at max pressure your tires will wear evenly and you will get much more life out of the tires!
Also, my experience is most tire shops will actually let the air out of your tires (even if you specifically request they not do this) to 30-35 when they rotate or balance, so check your pressures afterwards and fill them back up to 44.
