Back in the day when I was still running 23c tyres and you had to download websites to read them, I just ran them at 90 psi and that was a plenty harsh enough ride! Now I run 30c and 32c tubeless at around 60-70 psi. I weigh 175 lbs.

If you have clearance for 25c I would take those and experiment with lower pressure. Unless you weigh a lot more than me, 90 psi should be more than enough.
