But for a 32 mm and a not super heavy rider, experiment in the 50-60 psi range. More if you ride in a velodrome, on glass, or some other perfectly smooth surface, less on rough gravel. Lower pressures on wider tires (wider compared to the 23 to 25 mm many racing bikes use) are much more comfortable. Wider tires aren't meant for high pressure.
Ok thanks. I do remember when I was picking up the bike that the guy actually measured the width of the tires and they were actually a bit wider than the label (he said it was due to the rim). The other LBS also mentioned that the Domane series has wider than normal tires.
