I rode my fat bike 17+ miles yesterday on some single track trails. Nothing very technical but average single track riding with roots, logs, rock gardens, climbs, mud, frozen earth, ice and other similar obstacles. I ran with 8 pounds of pressure on a fully rigid bike and was surprised how confident inspiring the the fat bike handled. Note, we have no snow yet but maybe some coming Saturday
Lesson learned, when talking fat bikes, tire pressure is the key to an enjoyable or harsh ride. I recommend that everyone experiment and see what works for them. I like the idea of over inflating at home and letting air out along the way to find the sweet pressure for the ride.
