I've had 30/9:50X15, 235/75X15, 255/60X15, 225/70X16 on my 96 with no major issues. All but the 225/70X16 rubbed on occasion, either the rear wheel well or the lower control arm.
The 225/70X16 seems to work well, doesn't have the sway of large sidewalls, like the 235/75X15 or the 30/9:50X15.
I'm willing to sacrifice a little of "the look" for something that actually works well.
