I have run 33-12.50r15 KM2's on both my stock M1009s (which I am assuming from your signature is the CUCV you are referring to).
On one, they rubbed slightly on the very inside of the left front wheel well lip behind the wheel, but only when you flexed the vehicle with the tread edge adjacent to that point (does that make sense? As in, only when you were moving and the tread edge passed at the closest point to the wheel well).
On the other, it only rubbed at that point on the right! With a less knobby tire, I don't think it would hit at all.
On one vehicle, I bent the offending corner a bit with vice-grips. On the other, I trimmed a bit off with a Dremel tool. both "fixes" worked fine.
Pawnshop ran 33-10.50r15s on his M1009 with no issues at all.
The KM2's are noisy, but then the rest of the M1009 is too. Doesn't bother me, I always wear earplugs anyway. They seem to be wearing okay, I have put several thousand miles on them in couple of years.
Cheers
