285/75r16 cooper mt's on trd's after a light dusting about a month ago.
do you have a lift?
i'm not sure if either size would fit without one - i have a 3" all-pro lift and have not done the body mount chop and on rare occasions with extreme wheel turn i hear rubbing, without the lift i don't think there'd be enough clearance save for the smoothest of paved roads.
cheers.
