The recommended tire pressure should be on the actual tire. Tire pressure is not assigned by car, but by the different types of tires you can put on the car. You should find this information on the wall of the tire more towards the hubcap than the edge.
on the door jam of the car you should see a decal with the proper tire pressure for your car

Air pressure is the same throughout the tire.
No. A car will get better mileage with the correct tire pressure.
Tire pressure depends on the tire. The pressure recommendation that come with the car are for the specific type, size and rating that came on the car.
If inside and outside same pressure that means there is no pressure. The added pressure is what blows the tire up like a balloon and holds the weight of the car up.
The tire itself should have a "MAX PSI" number printed on the side. This number, however, is the maximum rating for the tire, and not necessarily the correct tire pressure for the tire on a particular car. Check your car's owner's manual or the sticker on the inside of the driver door frame for information on tire pressure. You can also ask your local body shop or gas station.
The maximum tire pressure is printed on the tire. Try looking in the car's manual for the correct pressure.

Inside the drivers side door there is a sticker that will tell you the correct tire pressure, gvw, and other misc. information. I think its on the car and not the door itself. otherwise the tire will tell you max pressure right on the side wall.
