Apologies to the OP for the departure from your P/S dilemma, but I wanted to discuss...
I don't follow the door sticker recommendations for tire pressure..... pretty much ever.
The tires on my Hyundai today are NOTHING like the tire construction of the 2007 OE
donuts that came on it. That's probably the closest thing to "stock" I own in the
suspension department. (Has Koni front and rear though) The ride is interesting at
the factory suggested tire pressures.... it doesn't get quite right until it's about 12
psi higher per corner. I am, however, somewhat compensating for leaving the
factory springs in place. Upgraded springs may actually lessen the tire pressure
At the other end of the spectrum is my '66 GT where NOTHING is stock in the
suspension. Bridgestone Potenza's with stiff sidewalls are way different than
50 year old bias ply 14 technology. Tire pressure are nowhere near what the
Ford shop manual suggests.
