If i look at my driver side door panel the PSI should be 30psi, If I look at the tire itself it says 40PSI.
What do I do? (FL)

If you look at the vehicle information tag on the drivers door frame it says the EXACT TIRE PRESSURE that should be used IN YOUR VEHICLE.
If you look at the sidewall of the tire is says "Maximum inflation." Note that it does not say "recommended inflation", just maximum, in other words, the not-to-exceed pressure. The tire manufacturer can not put a recommended pressure on the sidewall because they have no idea what kind of car the tire will end up on. Not all cars that use the same size tires have the same inflation requirements.
Go with what it says on the vehicle information tag. That information is specific to that size tire on your vehicle.

The reason the specs are different is because the car maker who put the spec on the door jamb label was looking to get a nice quite ride, even at the expense of tire life. The tire maker that put the pressure on the tire is looking for maximum tire life. I would go with the tire spec but it will probably make your car ride a bit harsher and give you a bit more road noise.

Car tells you the pressure for your car. Tire says maximum inflation pressure. thats what is the safe limit for the tire according to the tire manufacturer. Go by what the door sticker says for your car.

I'd do 40. When your tires aren't inflated properly you get lousy gas mileage. Have you looked at the specs for your car?
