i always imagined were I to be fortunate and live in Utah, Nevada or Colorado where dry rocks reign supreme, I would just run Treadwrights like those all the time. I imagine they are very grippy in those premo conditions and cheap enough to not have to care about them. Plus they look cool.
I've been running the Treadwright Guard Dogs for nine years now (32s and now 35s). They've been excellent in the Tennessee mud - they're great at highway pressure but aired down to ~18 or so it's crazy how good they are. They're a bit noisy on the road but I'm used to it now.
Didn't know they were looking into a 37 x 17 tire for production. May just have to stick with TW...
