235/85R16 is a factory size these days, though most vehicles have 7.50R16 on steel wheels.
265/75R16 will fit with no problems and used to be a factory size on 90's in the late 1990s, but will only fit on 7x16 rims - they were fitted on alloys by Land Rover, the 5.5" steel rims are not wide enough for a 265 (manufacturers will tell you they are also not wide enough for 235s but experience begs to differ!). I run 265/75R16 on Land Rover 7x16 alloys on my 110, and it causes no problems at all.
