Hook it up, put a chalk line or paint line down each tire tread (perpendicular) and drive so the tire rotates a few times or until you see where the line starts wearing most.
Wearing in the center too much, too much air pressure, let some out.
Wearing on the sides too much, too little, put some in.
The tag on the door is for OEM equipment 'recommendations.' You have different tires then forget that number.
