This one could get heated... It did the last time it came up which was a real long time ago.
The rating on the side of the tire is the max cold safe pressure the tire is rated at. There is a weight factor that goes with the max pressure. If you are going to load the vehicle to the max the tires can handle safely, you need to set the pressure to the max recomended on the tire.
The sticker on the vehicle is the factory recomended pressure for your vehicle with the factory installed tires. That takes into consideration, traction, handling safty, braking and vehicle load recomendations. I belive any like load rating and size tire the vehicle manufactures rating is fine. If you tow or fill the back with rocks you can run up to the tires max rating on the tire.
Taking all this a step further, just like at the track you can adjust tire pressure to suit your driving style. I would refer back to the vehicles recomdation and adjust from there. Hard tires will get you less traction than slightly softer tires. Hard tires will get you better gas mileage (less rolling resistance)
On rear wheel drive cars that the rear wants to come around before the front pushes you can lower the rear pressure and increase the front to correct some for the rear wanting to kick out through a corner. It won't make your H2 an auto crosser but if you drive real agressive around corners it might give you a bit more control.
The minute you get away from the stock size and rating tire and wheel you have to disreguard the factory rating on the door sticker and you are on your own based on tire load and max psi rating...
