The OEM recommendation is a good starting point and lets me know how many PSI over their recommendation I will add.
Note: The recommendation only holds for the same size tire so if you change the size, you have to figure out what the optimum pressure is for yourself.

This seems logical because I'd bet that when the tire company sells to the OEM, they've made a PSI recommendation that's a compromise between comfort and mileage. My guess is that for liability considerations, adhering to the OEM recommendation makes sense as well.
That said, there doesn't seem to be any real risk in a moderate PSI over the OEM recommendation. I'd start with 4 PSI additional in the front and 2 PSI in the back.

Tires are the single most important part of your vehichle, yet so many don't understand their importance to safety and fuel economy.
Sad.

If you are going to post a link don't just give us a blind link... give us a few sentences from the story to give us an idea what it is really about (more that a title)

Check the tire placard for your vehicle. This is the correct tire pressure.

Properly inflated tires will save fuel and is the safest way to drive. If a tire is over inflated, it can blow out as the air inside expands when the tire heats up from use. If at high speed, it can cause lose of control, overturn your vehicle and cause death.
If the tire is under inflated, It can build heat quicker as it has more rolling resistants. More resistance equals more friction; more friction is higher heat causing the tire to fail. Again if at high speeds it can cause lose of control, and accident and death.
Now with that being said, every vehicle has posted on the drivers door frame and in the owners manual the proper inflation for that make and model car. FOLLOW THE INSTRUCTIONS!!!!
Personally, I believe in the following two exceptions to the 'FOLLOW THE INSTRUCTIONS' rule:
First, the car manufacturer DID NOT make the tires, the tire company did. As such, I am a firm believer in inflating the tires to the max cold PSI imprinted on the tire by the manufacturer, and making all four tires the same as they are the same size tire.
The second exception is for four wheel drive vehicles. When a 4x4 is in four wheel drive, all four wheels turn at the exact same speed. Now when you make a turn, the limited slip differential in the rear end, absorbs the speed difference between the inner tire and outer tire, with the outer tire moving faster. However, in the front differential, most if not all are NOT limited slip. Tis accounts for the difficulty in turning the steering wheel. Both front wheels turn at the same speed and fight each other around the corner. That is why you should only use four wheel in mud, snow, sand or on any terrain that will allow the wheel to have the least amount of friction, enabling it to turn (slip) in time with the wheel on the other side.
Now by association, an under inflated front tire on a 4x4 causes one wheel to turn slightly slower the the opposite wheel putting undue stress on the axles and differential gears until something gives. That something can be as cheap as the tire and/or wheel or as expensive as the axels and internal gears.
What most people don't realize is the potential danger when changing a tire on a 4x4. If that 4x4 is equipped with a full size spare and the rolling circumference is identical to the other 3 tires, No problem. However, if the spare is smaller or one of those (shudder) emergency donuts, you may have to do a double tire change. If the back tire is changed with a smaller spare, no big deal even in four wheel drive as the limited slip differential will account for the sizes. In the front it is a different story. If you do not need four wheel drive, there should be no problem because the wheels are NOT engaged to the drive train and spin independent of each other. If you need to use 4 wheel drive, you will need to put the spare on the back and one of the same size tires in the front because when four wheel is engaged, the wheels ar locked into the drive train and turn at the same time. As stated earlier, the front differential can not absorb the tire size difference.
The last part is a bit off tangent and yet a bit similar. I hope this information helps.

Is there a point to your posting a link that simply opens a search page?
As you didn't provide any perspective to your original post, are you asking us to discuss tire pressure? Are you asking us what's the best tire pressure for your car? Or for our cars? Or are you looking for something else from us?
Or, are you simply saying, "Hey, I found this wonderful website that I think you should see, because you'll find it interesting, or will find it useful, [but I don't want to bias your reading of the issue by saying anything else about it]"?
