Between there and "too darn harsh" is the best the tire can do for you, on your bike, and on your terrain. On my Grand Bois 584 x 42 and Compass 584 x 38 tires I've done some of this exploration. I'm coming to dislike bike innovations that turn going out for a ride into grueling engineering. My tubulars are a simpler world to live in. Pump them up by squeeze, check you have a pump and some spares in the sack, and go.
