I'm the owner of a new, white, two-door Fiesta ST (I live in New Zealand), and after checking the owner's manual and reading various posts on-line from US owners of the four-door, I've noticed a huge difference in tire pressure recommendations for the two vehicles.
Ford recommends 39F/36R for the four-door, while for the two-door they recommend 36F/26R(!). I know there are some differences between the two (the two door is a hair lighter, and the US suspension was, apparently, tweaked a bit to pass US pot hole handling requirements), but they just don't seem different enough to justify such a massive (10 PSI) difference in pressure.
26 PSI also just seems insanely low to me, even for the rears. I've never run anything below 36 PSI before, and the idea of 26 PSI has me paranoid about pot holes and rim damage. But then surely Ford tested these out and know what they're doing? Anyone have the scoop? Any other two-door owners out there? What pressures are you running?
