The Surly Edna fat bike tire is designed to be a large volume, super versatile tire to take you through the seasons. In the Summer or frozen singletrack, Edna's tightly spaced center lugs roll quickly with minimal drag and open up to wider spaced lugs for traction in loose snow or sand.
At 4.3" the Surly Edna will work with most frames like the Surly Wednesday or Salsa Beargrease that are designed to fit a 4" tire or can be used as a "slimmer option" for fat bikes like the Surly Ice Cream Truck or Salsa Mukluk. Surly designed the Edna fat bike tire to work on fat bike rims ranging from 65-100mm in width with the sweet spot being around 80mm, which is the most popular rim width for fat bikes.
The Edna is the first fat bike tire Surly has designed to be set up with or without tubes. If you want to install these tubeless on a set of Surly Other Brother Darryl rims, you will need the Surly Tubeless Kit that can be found here.

Bought these tires for bikepacking. Seems to thorn puncture easily but with tubeless seals up just fine. Rolls well but has noticeable self steer, but certainly not overwhelming. Works well for packed snow and mixed ice. Not so good in mud as it packs up and slides around. Floats very well for sand.
