What tire pressure do you race with? I know this depends on race conditions and rider weight. The race I'm entering is mostly fire road type conditions with tons of climbing and not very technical decending. Some people I know race the course with a tire pressure of 60lbs with tubes and others race with stan's at 25lbs. Any suggestion? Rolling resistance is most important to me. Thanks-
first off, pressure gauges can vary and be uncalibrated, so one person's 38 PSI may be someone elses 42 (or whatever). A tuned in rider can most likely feel a difference between the two, so I agree with all the people that said stick with what you do now. That way no pinch flat suprises(too low), and or harsh feel/bad handling on the bike(too high).
BTW, I have timed myself on the same course at different pressures, and not noticed any differences.
I typically use 34-38 for the front tire and 36-40 for the back, according to my gauge

. (front tire fatter than the rear). I also use the 'finger' test, I like a bit of squish, not rock hard.
Bottom line, If you are comfortable and trust your bike, you will probably rip good times.
