Sorry for not providing you with the all the easy answers. Really guys! Get off your keisters, that's old guy talk for buttocks, and keyboards tomorrow. Get out and experiment. In racing circles (well road courses and even in a straight line) it is common to change the tire pressure by 0.5-10 psi from tire corner to corner to alter the handling characteristics of the vehicle be it a car, cycle, or truck. Your size, weight, how much load (stuff) you cart around, your driving style or purpose for the day. I gave you my numbers. My PSS's were too stiff when chalked at 36/42 for my style, as in high in the center.
Car manufacturer's and their legal departments are conservative for the most part. They are not going to publish or recommend tire pressures which achieve the best handling, at the risk of another Exploder incident. Because lazy people rarely check their tire pressures, especially now with the TPMS systems. Doah - Tire pressure must be OK - I don't have a warning message. Heck I get "On Star" messages in CA from my Yukon, now with my daughter in CO - so I can remind her to air up the tires as the cold weather closes in.
Enough said.
