See my avatar, that is a e100 German super tank, it weighed over 100 tons and it had a lower ground pressure than 34 ton M3A1 Sherman tank. What does that mean? In a muddy field where a M3 would sink up to the belly pan, the e100 would drive right over while being more than three times as heavy. Against the laws of physics? The e100 has 36 inch wide track, the tracks of the M3 were 23 inches wide. The e100 track ground contact patch was also twice as long as a M3..... this resulted in lower ground pressures..... what does this mean? Well, I have a shoe footprint about the same size as a aired down 4.6 inch fat bike tire (size 8.5 shoe). For me, if the trail is to wet to hike, it’s to wet to ride. For people that have 2.3 tires.... think of your trail ground pressure as two 2x2 inch squares (for a 29er, smaller for a 26er), so if you can hike the trails on stilts and not leave deep 2x2 holes, you can ride...... as for the xcross guys, it’s a road bike with knobbie tires.... keep on the road till we have a year with out rain.
