On a DS 8.5, I've got 47-622 (28x1.75) Continental Tour Ride tires, front and rear. On a set of Velocity Dyad 36H rims. Very stable and strong. Have done mildly muddy and rutted trails, though nothing very steep yet. Big difference, as compared to the 38mm's.
Rubs a bit with full-length fenders, but works fine without the fenders. Will need to reshape the brackets and toy with the fender stays, but I'm hopeful they'll work.
