The sidewall information tell you how much air is required to carry XX pounds (the load capacity of the tire).
Max capacity. But folks on here put more air in ??
No I don't think so. The pressure on the side of the tire is the max to carry the rated load capacity of the tire. Most folks end up with lower than that number. You shouldn't exceed the sidewall number cold.
Partially correct.
The number on the side of the tire is the MAXIMUM load that the tire can carry and the air pressure is the MINIMUM needed to carry that max load. In other words, if you put in less than the printed air pressure, the load capacity of the tire will go down.
Also if you have to carry the maximum allowable weight on a tire, and you inflate it to the Minimum tire pressure as printed on the sidewall, the tire pressure will increase as you drive and the tire heats up. This is all well within the design parameters for the tire.
One other things is that if you go to a higher load rated tire like from an F to a G rated tire, and you plan on carrying the SAME load that is within the specs of the F rated tire, the tire pressure will be the SAME with the G rated tire.
