I take "gear" to include the bike.

Interesting. It turns out that the calculations yield numbers very
close to what I have been inflating the tires on my bikes with 32mm
Paselas for a while now. An item of curiosity: the referenced

After answering my own, earlier foolish question, I played with it and find
it oddly close to my current practice for some tires, oddly off for others.
65 MM Big Apples, 200 total, 45/55: 12/16, which is close to what I run in
sand but quite a bit lower than I run on pavement.
33 mm Jack Browns:
Thanks very much for publishing this Jim.
I've tried to operate by Jan's tire pressure guidelines ever since he
published them, makes a big comfort difference on the chip-seal roads
I ride on.
I end up using the same tire pressures as the "go fast" club riders
around here...only by 120 psi covers
I did the fore-aft bike weighing, when Jan's article about Frank
Berto's tire pressure chart came out. My Quickbeam is 40/60 front/back
weight distribution, exactly as predicted, and my low-trail Ross
touring bike hit 45/55 exactly, also matching BQ's data. Your own
mileage may vary slightly.

Google documents will convert. I'll try to make
The above spreadsheet is based on the ideas in this article:
http://www.vintagebicyclepress.com/images/TireDrop.pdf
Toy around with the % front and rear, use a scale and a helper if you
can, and be Honest about the total weights, shoes junk you haul arount
etc. it will get closer than you think.

Almost as much fun as calculating gain ratios to ensure exact equality
across the fleet in the garage.
