Just got 2002 Monte Carlo.
Tires p225 60/r16. Got problem knowing the right pressure
The tires say 44psi, Google says 35, the door sticker says 30. How much should it be?
The tire pressures are listed in the door jamb sticker - follow those. The numbers listed on the tire sidewall are the maximum tire pressure - definitely don’t want to approach those.
door sticker is correct.
Look carefully at the tire sidewall it probably says "MAXIMUM". It tells you the absolute most pressure that the tire can safely handle. Not the pressure you should use.
