If your Canadian and own a Fat Bike your riding in the winter, in snow and very typically that means ICE. The Dillinger 4 and 5 are those tires for Canadian winters and ideally staying upright when encountering an icy section of trail. The first time you take a “hipper” you will want Dillingers. The price might hurt more than the fall but you will ride more and the pain will go away after you tear through trails and lakes with potential icy sections with only a big grin on your face (this feeling will happen for years because winter tires used in winter last many seasons). These are the best all round studded tire hands down. If your on the fence, realize that when you find out you want these things they will likely be out of stock everywhere.
