Generally, you should follow the sticker in the doorjamb as long as it doesn't contradict the tire manufacturer. Tire makers don't generally put recommended pressures on tires. They have maximum pressures, not recommended because there are multiple variables involved (vehicle weight, max load rating, top speed, temperature ranges, etc). The tire manufacturer trusts that the automaker will make solid recommendations based on engineering info.
The exception is if its Ford and the tires are Firestone. Ford recommended a pressure outside of Firestone's engineering recommendations for the Explorer when they had the exploding tire issue. Ford did it for ride quality issues, not safety.
