after the exploder/bridgestone debacle, i've never trusted door stickers since. i weigh my truck at the scale, then i do the math to figure out the psi i need to support it based on the tire manufacturer's rating. never had any problem of uneven tire wear, blow out, etc. ran my little geo tracker with E-rated tires at 25psi for 3 years. still had firm handling, even tire wear across the tread, never blew out on me. doing the same thing now that those tires are on my ranger. different weight, different pressure, but still the same calculations based on weight and tire rating. don't know why i should do it differently, but that's just me.
