for those with 205 50 16's
 

I have them also (falken ziex 912'4)

Just curious to know what pressure you all keep yours at?

I do 39 but this winter my ride seems harsher than usual.

37 front, 35 rear.

34ish all the way around. I say "ish" because the temperature fluctuates so much lately in VA, it's hard to keep track. (It's said for every 10 degrees fahrenheit you increase/decrease 1PSI, which I've found to be very true).

35 all the way around. The recommended 33 feels too squishy.

That sounds reasonable... I have found that when it gets cold the oil in the dampers thickens and rubber is less pliable so I have to drop the tire pressure instead of adding more air... I had been putting 35 PSI front, 31PSI rear with my old 195-55-15"s but the 205-50-16" Goodyear Eagle Authority tires... They are the same tire as Eagle GTs but with a slightly different tread sold only at Wal-Mart.. They are heavier and have much thicker sidewalls than other tires I have had on my 07 Fit... I have dropped the front to 29.5 PSI , rear to 28 PSI but the ride is still rough even when the ambient temperature is as warm as 50, 55 degrees F... I have my rear seats removed so I have to use less air in the rear tires than the front...

I keep them around 36 or try to at least, seems to ride good.
