Clutching makes a HUGE difference...and I dont mean a duner kit.....Mine does...well even with the 31s on it.I have 27" XTRs on my Outlander.....and they are one heavy tire!!
But on a serious note.....I dont think a rhino has the nuts to pull those pig tires on thick mud. Hell, I has 26" XTRs on my 660 rhino and it was clutched and modded and it didnt spini them like my outlander does!
I am not saying it wont move.....just saying it wont have the spinning power I would want, but to each his own.
