Fascinating pressure chart and 15% compression rule. Thanks. Extrapolating
it for 50mm tires and 190lbs (+ whatever weight I have in my bags), I'm
guessing my usual pressure is spot on. I'm actually quite comfortable with
my usual pressure (likely 40-50 psi) for paved, dirt, and trail riding. I
Deacon, there is a spreadsheet calculator built that uses the data from
Jan's extension and discussion of Frank Berto's earlier work. You can

Thanks, Bob and Phillip! My main gage is to have enough pressure to not get
snake bit on rocks or roots, but not a whole lot more than that.
With abandon,

My pleasure. I maintain the spreadsheet, but I didn't create the original
Excel formulas. That was Dave Adams, and he based his formula on Frank
Berto's measurements, as reported by Bicycle Quarterly.
Fellow list member Allan Folz wrote new formulae for the Android Tire
Pressure app we worked
Philip, thanks again. I look forward to looking at the new version. My
apologies for not citing you correctly in the first send. Bob

this was posted in an odd spot on another thread, but it's a very useful
article on optimal pressure and tire drop.

Sounds like the fenders fit about as close to the tire as possible. If
deflating to your normal pressure made the sound go away, bingo, you got
it! FWIW, once I got up to 40 mm tires on my Atlantis, pressure seems a
minor item. I pump the back up to 60ish front to 50ish, then ride until
