The tire says 35 pounds, and the door jam says 30 pounds

Go with the pressure that the tire manufacturer recommends. The reason is tire manufacturers test their tires for safety and durability based on the tire pressure listed on the tire. The tire pressure listed on the door jam is the tire pressure recommended by the auto manufacturer for a comfortable ride quality. (We all know what happens here with the Ford Explorers right?)
Always go by what the tire manufacturer recommends to minimize tire wear, get the safety recommended by the tire manufacturer (they test at that tire pressure) and get maximum fuel efficiency.
If you go by the auto manufacturer's recommendation, you may get a better ride, but you risk safety just like the Ford/Firestone fiasco. Ford had under inflated the firestone tires to the point where the soft ride caused excessive heat build up and tread separation.

The number on the tire (35psi) is the maximum cold pressure, the number on the door is the recommended pressure for the car. Don't go over 35, you risk tire failure, and don't go under 30 you will get bad tire wear. If it's only you in the car most of the time or you like a soft ride stick with the 30psi, if you have a heavy load or like a firmer ride the try closed to the 35psi. you could just split it with something like 33, that's what I do, I keep mine at about 34.

The sticker on the door is for the tires that were originally placed on the car. If you still have the original tires you should go by the door, if you bought new tires, you should go by what the tires say.

It looks like most people are saying tire but they are wrong it is by the door sticker . What is on the tire is maximum pressure and weight the tire can safely carry, so unless you have your vehicle loaded to the max, you do not need to put in what the tire says. the only exception to this was when Ford put on firestones on their Explorers and had to low of pressure on the door.

The tire is a max rating.
The one on the door is per the car maker, which is for the best ride.
I've found that the lower pressure makes the outside of the tire wear faster, but it gives a softer ride. So I go with a few pounds more than what's listed on the door, pretty much what mikey said, about 32.

ON the tire because maybe different tires are on car than were when new.........that happened to me. My son bought a used car and it had the incorrect tire size , so that made the door jam sticker incorrect!!!!
The sticker does tell you the correct "size" of the tire but not the inflation.

How would the door jam have anything to do with the tires you have? Perhaps that's supposed to be a rule of thumb. The # on the tires is what you should go by.

The vehicle manufacturer is recommending a pressure of 30 pounds, which will give a softer ride. Fuel economy suffers though at lower pressures. I normally run mine at 32-35. Also remember to check your tires once a month, or at least when the seasons change.

***go by the TIRE. the sticker on the door jam is assuming you're using the tires recommended for the car.

Go by the tire, as they may not be the ones that were originally on the vehicle, and that sticker only refers to the original tires.
