26~26.5 psi is my 99.9% setting. I saw you used to live in AZ, so you're probably familiar with loose kitty litter over packed kitty litter condition our trail system shares with the neighboring trail system Bootleg Canyon. Any more psi and the bike starts getting a bit too drift happy.I could definitely do that at 26psi with a 2.3-2.4ish tire if I hit a rock hard. 165lbs. Either set your pressure high enough for 100% of anticipated situations, or low where it works for 99.9% of terrain, but when you encounter that 0.1%, it'll dent your rim...
