What PSI for 32mm Conti 5000 TL?
I'm trying out the 32mm Conti 5000 Tubeless on my gravel bike for a road ride. What PSI do you recommend? BTW I'm 150-lbs.

Play around with it. Preference is certainly going to come in to play, but one of the guys that I ride with, who's about your weight and is also running 32mm 5ks, is running them at ~50psi on pavement, less on gravel, IIRC.

If there is a min and max pressure, then put it in the middle. Ride a few rides, try 10 psi up or down, ride some more. What do your legs tell you while you are on the bike making some effort?

According to Continental, the range is between 65-87 psi. I’ll start at 70 psi and go from there.

I have found this online pressure calculator to be very good at getting me in the ballpark.
I am making some assumptions about the weight of your bike and weight distribution, but it looks like something in the ballpark of 45 front and 55 rear is a good starting point.

70 psi seems high. I'm 150 lbs and run my Conti Ultra Sport II (with tubes) around 70 psi for 700x25 on the front, 75 psi on the 700x23 front. No problems, even inadvertently hitting some rough spots hard. I could run those lower.
On my hybrid I run 700x42 tires around 35-40 psi front, 40-50 rear. No problems.
If I had 700x32 tires on a road or endurance bike I'd try around 40-50 psi, at least on the front, for gravel.

Is the question.. how low can I go, and get away with it without handling, flatting, or some other issue? Or, what is optimal for performance (lowest rolling resistance for the terrain I'm riding)?

I normally pump new tyres to the max that is stamped on the sidewall on the rear, and a bit less for the front
I ride them for several days and when they feel perfect, I check what the pressure is
