In order from tending to be shortest to tending to be tallest you have:
305/70R16 = 33x12.5R16
285/75R16 = 33x11.25R16
255/85R16 = tall 33x10ishR16
Sometimes they end up taller, shorter, narrower, skinnier, etc than advertised. A friend of mine had a set of 285 Cooper STT's that were most of an inch taller than a similar set of 285 BFG AT's on another friends' similar size and weight fullsize pickup.
