What Pressures Do You Use?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

The front shows very little compression of tire (visually), the rear a bit more.
Do you get pinch flats?

No, never. My roads are pretty average... I don't think I'm hitting more or fewer potholes/rough patches than most others and about all I do is lift the front wheel over some of the worst of it (where possible).

Maybe the tire size (28 mm with actual 26.5 to 27mm width) helps, but I also sometimes use 23's (actual 24mm) at 70 psi front and have yet to pinch flat (I haven't used them as much, though).

That's what I run @ 140 lbs. Suppose I could go down some, but I never flat and want to keep it that way. Roads are somewhat rough too.

Charts be damned, I go with what's comfortable/works for me with my usage. Road bikes, both 700/25, 100+ psi on one and 90-95 psi on the other...both front and rear. 200 pounds good weight fit I am.

Im 125 lbs
65 front, 70 rear on 28's is usually the max I can run without it being too harsh. 60/65 feels better. Theyre Vittoria Randonneurs and max out at 85 psi.

Agreed,

The charts like the one I posted can give a starting point if a person is not sure where to start. The chart is what prompted me to try a lower pressure then I had been using and I found the lower pressure and wider tires improved my enjoyment for the way I ride.

I of course did not intend to demean the use of charts as a starting point. The way I now search out my personal sweet spot with a new bike/tire/wheelset is to start with higher, watch how it feels as the tire gradually loses pressure, then work around what seems to feel/work best until I settle in on something. That's how I arrived at different preferred pressure points for two different road bikes with the same wheel/tire size,
