K30 dually tire options. Anyone running humvee tires?

[dragn91]

Just picked up a old beat to hell crew cab k30. I want to install a more aggressive tire on the truck before the dry rotted ones on it explode on me. I'm torn between buying a set of 255 85 16s for the truck or getting a set of humvee 37 inch tires. I have a set of 16.5 dodge steel wheels off a old camper, Would those work for that? If I run the military tires I think I can leave the drive train alone i think it's got 4.56s in it. If I run the 255 85 16s I think I will swap out the trans with an overdrive nv3500 or 4500 if I can find one to help on the highway a little maybe. If anyone is running a k30 with a more aggressive tire please post up some pics and info. . Google has failed me on the info part.
