What tire pressure are you CX bike riders running on trail?
Airing up for pavement?
Hey Tinman, that's a big question. 33mm or 35mm or more? Tubular or clincher? Fine tread or Knarly?
I use Schwable 35mm Rocket Ron (front) & Racing Ralph (rear) on pavement and gravel @ 50psi and 55psi respectively. How you want to balance the Front/rear ratio makes a difference too.

BRAKES...? I'm trying to go FASTER!!!
That (50-55psi) gives me a good idea with out excessive detail. I see most those cx tires rate at 70-100. I have the hots for a cx bike but, besides cx I would like clearance for 45's (monster cross)............I will likely have to give somewhere
I don't bother airing up pavement
At 250lbs, I air my tires up to 60psi, but no higher. 2012 Jake the Snake stock setup.
Trail 40 or 45
Race courses 30-45
Tires usually 32s, I weigh 225ish
Yeah I only carry cans cause I'm a weight weenie.
I weigh about 165 lbs, am running 35c clinchers, set up tubeless, and am around 28 psi front and rear. Sometimes 25 psi.
Edit: Sorry just reread the OP. i use the above pressures for racing. For trail/training/singletrack i air up to 30-35 to minimize chance of burping or rim strikes on rocks since i'm usually farther away from help if needed.
I ran Clement PDX 32mm on a Ridley X-fire disk last year, with tubes filled with Stans.
I weigh about 165 also and raced them 40 psi rear, 35 psi front (many of our race courses integrate trail). One course was high speed over rocks and I pumped them up 5 psi more. Didn't pinch flat but many others did.
I'll pump them up to 50 psi or so if I'm bike commuting the CX on pavement only.
I run conti 700x43mm tires, knobbies. About as large as my bike will fit. Off road I run maybe 65-70 . I'm about 210 so that's a balance between traction and snakebites
I run 700x40 Schwalbe Mondials tubeless and run 28f/30r on and off pavement:
