Beastly traction

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.

Replacements for my Fuji Wendigo fat tire bike. Avid rider, 5 days a week on dirt, gravel and paved surfaces say 100 miles a week. Customer service was excellent, shipping was fast, product was well packaged and easy to install. I tend to wear out my rear tire faster than the front and I certainly don't baby the bike at all. Switched from Maxxis brand that was discontinued and hoping these hold up better. Going from 120 tpi to 60 tpi and hoping for improved durability. Time will tell.

Good appearance all around.

I have only ridden a little on this new tire but the appearance of quality is very good. I have used other Surly tires and always found them to be excellent.

One problem I had with this tire was specific to my bike. I had always used a 4" rear tire before. This 4.3" tire had corner knobs that hit my chain stays slightly. I had to trim off the corner knobs both sides to get completely clear of the chain stays near the seatpost. My fatbike is one of the very early designs and I doubt that anyone thought tires would go beyond 4.0" at the time.

This tire also locks well into my tube type rim. I've had tubeless tires where the bead was too big inside diameter and would pot out of my tube type rim. I'm using tubes with rims originally made for tubes. This tire fits OK.

I used it in the snow and hard packed snowy single track. Very good traction while braking and cornering. I only bought one to use on the front, but will buy another one for the rear soon.

Mounted the tires ghetto tubeless with no problem. Lateral lugs are aggressive and located well to the outside of the tire for confidence on corners or off camber terrain. So far have ridden in lots of mud and loose rock and have been pleased with traction. Looking forward to riding in snow. I would have liked it if the center lugs were just a few millimeters longer since I ride on mostly soft surfaces.

Very good all conditions tire

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.
