it's clear the OP doesn't have the handling skills of an experienced rider, which is something that only comes with riding time. I have ridden on worse on 30mm tires, but I wouldn't say it was particularly confidence-inspiring, and I wouldn't recommend it. And I wondered if I was going down a couple of times. PA DCNR has been known to lay down some pretty thick gravel in places, it can be a bit scary at speed. I'm riding 38mm GravelKing small knob right now, and they are pretty stable at low pressures, 30-40psi. Descending on my mountain bike is better, 2 3/8" tires at low pressures.
