I am curious as well. I have the stock Maxxis Colossus 4.5s on now and have an interest in something a bit more “racy” for summer. I am curious as to the ride trade offs as well. I have a 29+ Stache, so the fat bike will be occasional use and as my bike when my son wants to ride with me.As everyone is aware of, tires are a bit in short supply. Im new to fat biking this fall and have my bases covered for the winter with Snow Avalanches studded. No they aren’t the best, but they will get me by for now. I’m looking forward to next spring for when I can take these off for set of summer tires a bit lighter. I’m torn between staying full fat (Barbegazi, D5, cake eater) or going 4’“ Van Helga, D4 or Cake Eater 4.0. This is just for general purpose double and single track in New England. Htere is a lot of rocky, rooted out trails. My wheels are 27.5” Mulefut 80’s. I’m on a Growler with a Mastodon fork. It looks like Van Helgas are available. Terrene stuff will be soon. I can get a set of D4 60 tpi locally, but I balk at 60tpi. Im even entertaining Yippie Ki Yay. This is my year round ride Thoughts?
