My entire wheel journey started because i wanted to get away from the 16" wheel size. If I had known the 35" MTR in a 15" was going away, I would have gone straight to 17s.
Off topic .. but do you know anyone running Kenda Klever RT? They make a 33x9.5x15 that I am curious about. You also get a 35x12.5x15 in a load C. I vaguely remember @BuildBreakRepeat was going to try them but not sure if he got them or not.
