Unfortunately, I have no experience with them but I do see they come in both 35x12.50 Range C and a 315 Range D. The latter would offer a stronger sidewall and I might go with that if I were to run them. The tread looks agressive and depending on what the rubber compound is like, it could be a good tire.
I was thinking of the MTRs but everybody has talked me out of that! I like the Toyos but I want to stay with 15's and Nitto trail does not make that size or I would do that, I have terra grapplers now and love them but its about time for some new shoes.
