Though I'd guess that for many, the superior tread choice availability of the admittedly much wider 285/75R17 might be more practical if they have the clearance to fit them. The LT285/75R17 is a niche tire as well, but they can be readily sourced. I like them enough that I might run a set up to the Canadian Arctic next month.❄️❄️
Wish I could buy 285/85R17 or 285/80R18 tires 
I would love to hear an update on the MasterCraft courser CXT. I read your attached article, and I have owned the courser CT in the past and I really liked that tire.
The CXT is on the very top of my list of soon to be, next tires, and would really appreciate your updated review of them. Since you've had them for a year or more.
Will the 255s work well aired down (20-25psi ish) and cornering going fast or will they get squarmy. Would a wider 285 be a better option?
