Should I set my tire pressure by the door sticker or the tire max?
The correct tire pressure is the number listed on your car's door placard or manual, not the maximum PSI printed on the tire itself. Inflating tires to the tire wall's max rating leads to harsh rides and uneven tire wear, while following conflicting advice leaves drivers unsure of their actual recommended setting.
