175 rider + bike at sub 20 and another sub 25. Elk Pass tires, measuring ~27 and ~29 respectively; run at ~65-70. I don't sweat digits f/r, but I do use the pinch test to get front a wee bit softer. In fact, were it not for the gauge on the pump, which for all I know may be defective, I'd just go by feel -- indeed, I do, since the reported pressures are chosen because they feel right to my fingers.
When I used 23 mm tires on these bikes, I'd pump those to~80/85 or 80/90. 51 mm Furious Freds with at least half miles on sandy dirt: ~18/22 or 20/25. I'm pretty sure that the pump gauge reads too high, and I occasionally check with my low pressure gauge. I remember long ago, circa 1972, learning to pump my Raleigh Sprite's cheap 27 X 1 1/4 tires to the 70 psi marked on the sidewall. What a difference! Higher pressures *certainly do* improve rolling, at least the feel (and no, not any goddam buzz; they were easier to pedal and went faster) compared to too soft -- I've verified this any number of times with cheap tires with heavy sidewalls. The roads in question ranged from super smooth to normally worn, nothing terrible or chipseal. Question: just went out to check tires with gauges and found that the high pressure one -- to 160 psi; steel and brass -- doesn't register anything despite an open valve core and road pressures as above. Does anyone have any idea about what might be wrong with it, and how to fix it? Does anyone have a road presta gauge, reasonably accurate, to trade for something or sell for a few bucks?
