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 have used this here in the Pacific Northwest as well as the trails all around Sedona. It handles all these conditions extremely well. Rolls nicely, grips nicely and appears that it will hold up. Zero complaints.
I am new to fatbiking and I quickly learned that studs are necessary to ride during the winter in my area. Before having studs, I fell constantly. My tires would lose grip and slide like crazy on all the patches of ice. Getting the Dillinger 5s was a big improvement. The bike was able to stay upright better on the patches of ice and there was not any noticible difference in speed or performance. HOWEVER, I have still managed to make these tires slide out when I ride quickly into corners or other aggressive maneuvers. I have just learned that I cannot ride as aggressively as I typically do in the summer on my full-suspension mountain bike. I would still recommend the Dillinger 5s as they seem to be some of the best snowice tires available. But do not expect to gain unlimited grip.
