What's your tire pressure
What tire pressure do you guys like running for dirt road rides and small off road obstacles on your cx bike? I'm currently running Maxxis Raze 700x35c tires but looking to get a base tire pressure to start at. I'm new to the CX world. Thank you.

what is the weight of you and your bike? Tire pressure is pretty meaningless without that information.

I run my Clement MSO 36 tubeless at around 40 PSI for all around riding. If I am doing mostly off road I would do 30 in front 35 rear. I am about 175 lbs+ 20 lb bike.

700 x 32c,
175 pounds with ride gear plus bike, call It 200 even.
Working my way down from the max psi of 80...
Now at 65 rear 60 front on pavement and It's starting to feel dialed In.

I stay way higher than most everyone.
230#
25# bike
40mm Clement Xplor MSO tires.
75 psi most of the time.
Ive tried the whole go down to 55psi approach and its just too much out. Im rolling on what looks like a flat tire (even though i know it isn't).

On the Old Sheldon Brown site, that was his eyeball tire pressure methode when no other way was available.

55 psi for road and gravel rides, 40 psi for gravel and worse rides. If I have no idea, I go high and I'm always able to drop the pressure if it feels like I need less.

220lbs of bike & rider on Clement USH & tubes. I run 34F/54R on gravel, 40F/60R for more road than gravel. Meiser 60psi tire gauge is worth every penny.

Around here, dirt roads are roads. The OP didn't ask about CX racing. For "small off road obstacles" on clinchers, I'd certainly opt for much higher pressure than that used to go around hairpin turns in a muddy field. 20s or 30s of psi are going to cause rims to bottom out on the rocks or roots encountered on trails or unmaintained roads. FWIW, I (same weight as you) recently pinch flatted a 35mm front tire at 45psi bombing down a dirt road littered with river stones. If I went back to that road, I'd use a bigger tire or more pressure.

155 lbs rider + 25 lbs bike
Clement MSO 700x36c Tubeless run on 26mm internal width rims at the following pressures:
Paved Road: 60R/55F
50/50 road/gravel 45R/40F
Gravel only 40R/35F
I like even numbers what can I say. Could probably go lower, as I've seen some people heavier than me run - but I like to curb drop and ride up the occasional step on my rigid drop bar bike and afraid of the burps. And when I say gravel I mean very bad roads on the level that sedans could not drive them.

40, all three. I ride at that pressure regardless of terrain and also in the winter (on my Schwinn Cruiser SS).

190 lb rider, 27 lbs bike + gear, 700x38 Compass Barlow Pass extralight tires, on H+Son Todestrieb rims (about 26mm internal width). For most riding, I run 42 psi rear, 34 psi front. I definitely shoot for the 15% tire drop. On narrower rims (19 mm internal width), these same tires needed to be 5+ psi higher to be stable in hard turns.
On another bike running 700x32 Panaracer Paselas on 18mm internal width rims, pressure is 65 psi rear and 55 psi front.
