Pete LaBorewrote a review of 45NRTH Flowbeist Tubeless Fat Bike Tire on February 12, 2017
Familiarity: I've used it several times
I've got this paired with the Dunderbeist rear as a pair and so far have been impressed by the grip. Others have mentioned sidewall issues, but no problems for me so far after 8 rides.
Pros: Grippy, ability to go tubeless
