I started higher and lowered until I felt the traction was adequate. As my
time with the bike was limited, and I didn't have a 29×3 tube on hand, it
didn't make sense to experiment with lower pressures once I was happy with
traction.
That squirrelly feeling you describe is certainly present on regular fat
bikes, and I was able to get the Knards squirming/folding on grippy gold dirt
– so at 14 up front I felt I was nearing the point where I wouldn't want to
run much less pressure on dry ground. For the record I weigh around 180.
The folding bead Knard weighs 980 grams, which, for its volume, is actually
quite light, but on the scale of 29er tires, is among the heaviest. This
translates to a relatively thin sidewall that doesn't give amazing support at
low pressure. You've got to compromise in one direction or the other, and
heavy tires feel dead on such big wheels.
