The old M/T spec sheets for the Sportsman front tires listed the 28" front (which I also used to run) as actually being 27.5" (maybe shorter?) tall. I know when I replaced them w/ the 215/75R15s on my Challenger's 5" rims that there didn't seem to be much difference in how the car sat, and I went w/ the 215 rather than the 205 because of just that little extra height.
