This would be answered pretty quickly in the ZJ forum, since it's more vehicle specific.
However, that size will fit fine on a stock ZJ. I think that's basically the same size, if not a little smaller, than a 30x9.50/15, and those fit a stock ZJ perfectly.
IIRC you can actually go to a 235 on a stock ZJ, and a 245/75/16 wshould fit with some minor trimming of the plastic bumpers.
And FYI, you can do a 2" coil spacer lift (referred to as a Budget Boost, or "BB" for short in Jeep-speak) for less than a hundred bucks, then 245/75/16's will fit PERFECTLY.
I ran this combo for a few years when I first got my ZJ and it was great.
