Maxxis Minion DHF 2.5 – 30psi front and 30-35psi rear. Both tubeless. I find that any less than 30 and the tyres fold over and squirm when pushed into corners. The GF runs 20psi front and rear.

Do you mean as measured by my track pump or by my topeak digital gauge? They seem to give wildly different values.

Lowest I’ve ever used is 3psi front and 4psi rear (snow) and highest is 90 front 100 rear (road bike). Usually aim for something around low 20s front and mid to high 20s rear on a “normal” mountain bike (whatever one of those is these days).
