It should also be noted that manufacturer and other variances exist. I forget the make of my previous 32x11.5's, but Actual measurement (and most, really from what I've read) is more like 31.2"x11.0" I realized this after parking next to some 31's that were physically taller.
*shrug* get the tires you like most/find a deal on/etc.. It should work. If they don't fit, welcome to the world of trimming. Just make sure that if you're timid about body damage/trimming that you flex test in a controlled environment before the trail does it for you.
