I replaced a set of 45NRTH Huskers with these Ednas to get more tire volume (4.0 4.3). The difference is amazing on mud and other slick surfaces. The rolling resistance seems a little higher though so it's more work to push them along. They installed tubeless first try with the help of a tube to set one bead. No leaks or flats in 250 miles so far. Good price too.
I ride my fatbike mainly in winter on both gtoomed and ungroomed trails. Very good traction and less finicky for tire pressure. It has Rollins quite well and rather light weight at 1240 gms.
The only time I had some issues was on ungroomed trail w dry.granular snow and steep hills w loose snow. In these 2 conditions, fatter tires w larger wider spaced knobs work better. It replaces my fbr 26x4.8 as rear tire.
