The door sticker only applies to the original tires that were on your truck. If you replace them with the exact same tires that door sticker will still apply. If you replace them with anything else go by the tire or the load/pressure table provided by that tire manufacturer.
This is the key. If you want to go by charts and precise weights, that's fine. If not, max pressure as listed on the TIRE is what you should run while towing. The stickers are meaningless once the OEM tires are off the truck.
