Maybe this is a dumb question. I've wondered how to get the "Perfect" tire pressure. I'm only guessing, but I would guess that the perfect tire pressure is based on a number of factors, including the weight of the vehicle the tires hold, the temperature of the tire, etc.

I would also guess that the perfect tire pressure would be a pressure that allowed equal weight to be distributed across the entire thread at a specific speed, or tire rotation, centrifical force considered, etc.

I'm sure the NASCAR pit crews have this figured out to a precise calculation.

Is it worth something to consider? or is just guessing at a pressure around the manufacturers recommendation good enough?

On the street (as opposed to the track), any "perfect" tire pressure would remain a compromise between low wear rate, adhesion and ride quality (lower pressure) and heat resistance, gas economy and load capacity (higher pressure).

Also on the street, whatever "perfect" pressure you end up with will be closer to what the car manufacturer recommends, as opposed to what the tire manufacturer recommends on the sidewalls.
