That said, I know Jan doesn't use more than 50psi in his, and is content to let them get down to about 30 before re-pumping. One thing about these 38-42mm tires on road (erm, and FG/SS
) bikes is that it's nice to get back to the low-maintenance aspect of the MTBs/cruisers/BMXes many of us started with.
The more I think about it, it must be the gauge. I can easily depress the tire with my thumb, and when I sit on the bike and look down I can see a generous amount of deformation at the rear contact patch.
I've also read that you should use a gauge that it's max capability is at about where you run the tires because the farther you get away from the gauges max, the readings become progressively less accurate. According to what I read it was significant too. Mine is an old 160 max. Doh!
