I can't advise you on whether the sidewalls will clear the tie rod ends but my guess would be yes. I run a Yokohama tubeless radial on mine and although they have a narrow profile, they are about the same diameter as the 235/85 16s.
The tires you mention give you 653 revs per mile (ref The Tire Rack Specs). A 4.56 ratio will give you 4.56 x 653 = 2978 rpm at 60 mph.
