Factory specs: 32 PSI

On my 2011 Fiesta I ran sidewall max, 44 PSI, on the original tires (Kuhmo Solus) that came on the car new. At just over 30k miles, when I sold the car, the tires looked to me that they would easily do another 30k and there was no sign of any uneven tire wear. Thats 27k miles with no problem whatsoever.
