scott_10k_lakeswrote a review of 45NRTH Dunderbeist Tubeless Fat Bike Tire on March 4, 2018
Familiarity: I've put it through the wringer
These tire’s sidewalls are horrible. They’ll withstand one tubeless mounting. Next season, forget about tubeless, as you’ll see things like:
Bead separation from sidewall
Holes in the sidewall
A tire this expensive should survive more than one tubeless mount; more than one season - especially if they’re only used in snow.
I think 4tnrth must know about these issues & are quietly shipping newer, more robust versions of this tire as old, bad inventory gets depleted. How do I know? I’m on my third flowbiest, and it is noticeably different (in durable/good way) than the first two.
